Explain how object-oriented design allows changes to be made in a class definition without affecting other classes in the application.Explain how object-oriented design allows changes to be made?
the question is a bit vague but anyhow this is sometimes performed using Interfaces. An interface is only an access gate for other objects so when changes occur in the object implementing the interface the interface itself remains untouched and other classes would not change. However, sometimes cascade of change is not avoidable.

What happens when the frequency of a vibrating object is increased?
what happens when the frequency of a vibrating object is increasedWhat happens when the frequency of a vibrating object is increased?
c) the pitch is raised
What happens when the frequency of a vibrating object is increased?
frequency = 1/T. Thus when frequency is increased, time period of vibration dcreases. Thus, it vibrates faster
it takes more energy?
it makes a higher sound?
it puts more stress on the object?

How do you choose the best Doctor, if you are diabetic and money is no object?(to a point)?
Any one out there knows a good doctor can get rid of this sickness? I don't feel sick at all, until I go see my doctor and find out all the bad thinks that could happen to me, and tons of medecine he tells me to take. I am affraid to take them.How do you choose the best Doctor, if you are diabetic and money is no object?(to a point)?
you need to go to a specialist (endocrinologist) they can evaluate your diabetes and get you on a regimeboth diet and insulin if need be.How do you choose the best Doctor, if you are diabetic and money is no object?(to a point)?
First of all, diabetes is not curable but with diet, medicine, and exercise, of course, it can be controlled. Secondly, call your health ins. provider and ask for a few names. TRy to get a dr. who is affiliated with your favorite hospital, go from there. God forbid you are ever in the hospital for this, your Dr. practices there. If you are prescribed pills to manage the Diabetes, take them. Faithfully. Try all the above things also. All the ill occurances from this disease can only progress if you let them. Your Dr. must tell you about it so you're aware. Insulin could be far off and that is up to you.
Usually diabetes is genetic or because you are obese. You cannot just get rid of it though. :( If you are genetically obese you should be taking the medicine to help control it. If you are obese you need to get your weight down.
My mom had genetic diabetesand was obese too. She had a weight loss surgery (which is NOT the answer in my opinion) however, she lost like 80 pounds or so and now she doesn't have to take insulin shots of medicine because that extra weight has helped. She will always be a diabetic and will need to monitor her blood sugar and see a doctor if it starts to get out of control.
I have a few things on my page I would like you to read.
Diabetes can be controlled by medication. It is currently incurable. if you do not trust your doctor, seek a second opinion. A good person to ask is the Director of Nursing at your local hospital. Just call %26amp; ask for them. You will be given a list of names - usually three - choose the first! All will be good, however, because no Nurse will give out the name of a bad doc.
If you do not treat your diabetes, you will become sicker %26amp; die from it or the complications.highlight colors ointment cream

When blue light strikes an opaque object whose resonant frequency is lower than the frequency of blue light ..
When blue light strikes an opaque object whose resonant frequency is lower than the frequency of blue light what happens?
Does the object become warm?
Does the amplitude of the vibrations of the electrons in the object beome larger?
Is the blue light absorbed without remision?
Is the blue light reflected by the electrons in the object?
Is the blue light transmitted through the object?When blue light strikes an opaque object whose resonant frequency is lower than the frequency of blue light ..
So you're saying that the resonant frequency of the opaque object might be that of red light. Blue light should be reflected.

If color is seen on an object because light is shining on it, why is it always the same color to the naked eye
even if the shade is a different shade, why is it still the same color?If color is seen on an object because light is shining on it, why is it always the same color to the naked eye
Actually the color of an object is because of the portion of the light spectrum (color) that is reflecting from it. All the other colors are absorbed. Whether the light intensity is high or low, the same color will be reflected from the object.If color is seen on an object because light is shining on it, why is it always the same color to the naked eye
It isn't. If pure white light shines on an object then the colour it reflects is said to be its true colour. If however you view that same object in a different coloured light, it will not appear to be the same colour. For example a yellow object viewed under monochromatic blue light will appear to be black, because blue light contains no yellow, so there is nothing to be reflected. A yellow object seen in monochromatic yellow light will appear to be white because 100% of the light falling on it will be reflected and your brain will adjust to make it appear white. Try looking at daffodils under sodium lighting and you will see.
Hi. Take a red object out in the moonlight and you'll discover that what you are saying just is not true. Red is black in the moonlight.
Other than shade variance, the reason that red is still red, blue is still blue etc. is because unless there is the absence of light the eye will still see color.
It isn't really light ';shining'; on it, color is seen when light fragments reflect off of an object and back to the eye. That's why colors ';pop'; more when there's more light absorbed or reflected from them (ie blue in dim light looks different than blue in bright light).
Things appear a certain color because they reflect only one particular wavelength of light. If the light shining on it does not contain that wavelength, the object will appear black. Happily, most light we use contains all wavelengths we can see..............
wavelength remains constant

What is the acceleration of a freely falling object?
From an initial velocity of 0 m/sWhat is the acceleration of a freely falling object?
Acceleration on any free falling object is always equal to the force of gravity, which is 9.8m/s^2.
Since acceleration is a vector quantity, it can be denoted as positive or negative. In this case, since the object is moving downwar and not up, acceleration would be negative and so equal to -9.8m/s^2.
Good luck.What is the acceleration of a freely falling object?
Depends where you are. At sea level it is 9.81m/s^2. The Newtonian law is:
a = GM/r^2
where M is the mass of the body you are falling towards, and r is the distance to its centre. So for bodies of the same density d=M/R^3, this means that a=GRd, which is why the acceleration due to gravity is so much greater on Earth than on the Moon.

If the object is exactly at the focal point, then the outgoing light will be exactly parallel -- so it will never form an image. You could also say the image is infinitely large, but infinitely far away from the mirror.highlight colors ointment cream

Has anyone ever had someone send them an object on Ebay that was broken? And how did you resolve the problem?
I bought an Xbox 360 from someone over Ebay, I got it promptly, but the Xbox 360 is defective and doesn't play any disks. I have tried to contact the seller many times but he is ignoring me. I have to wait 6 more days till I can have Ebay get inolved, however I am worried that I will somehow be stuck with my defective unit. Are my worries grounded, or will things work out through Ebay? Thank you, I would just like an opinion of what is going to happen through this process of getting a refund or a new Xbox 360.Has anyone ever had someone send them an object on Ebay that was broken? And how did you resolve the problem?
Since I am guessing you paid a large amount of money, I would do what I did in a similar situation. I emailed the seller that if I didn't hear from them and receive a response and solution, that I was going to dispute the charge on my account. If you receive defective merchandise and paid via credit card, you call them and dispute the charge. Cards come with insurance. It is also possible to do this via debit card, but you have to call your actual bank for that.
Good luck.
P.S. I ended up going through my credit card company, and got all my money back.

What happen to the acceleration of an object when the mass is cut in half but the force remains the same?
Force = mass * acceleration ==%26gt; acceleration increases if mass decreases and force remains constantWhat happen to the acceleration of an object when the mass is cut in half but the force remains the same?
Just use an example to answer your question.
Force (F) = 100 N
Mass (m) = 10 kg
Acceleration = 10 m/ s* s
Now divide mass in half
Mass = 5 kg
Force = 100 N
Acceleration = F/m
= 100/ 5 = 20 m/ s*s
So since 20 is twice 10, the acceleration doubles when the mass decreases. Makes since when one realizes that something with smaller mass has less area and possibly less weight.What happen to the acceleration of an object when the mass is cut in half but the force remains the same?
depends on the volume. if volume is reduced then acceleration should be substantially increased. if not the moderately increased.

How does the size (radius) of an object affect escape velocity?
The larger the radius, the farther the surface is from the centre of gravity, so the lower the escape velocity at that point.
Gravity is inversely proportional to the square of the distance between the objects.
So if the Earth was twice the radius as now (but the same mass), then the surface is twice as far from the centre of gravity. Which means the surface gravity (and therefore escape velocity from the surface) would be one quarter what it is now.

i have. nobody believes me but thats ok i know what i saw. and i do think life on other planets exist, we have no way of knowing whats beyond our own solar system with our current tecnology, but i think its stupid to think we are the only planet in the whole universe with life.UFO Sitings anyone? I am just curious to see who has seen a flying object?
UFO? Not exactly... However, when I was little, a voice woke me so I ran into my parent's room and woke them. I was instructed to go back to bed. I complied. On my way back into my room, I remember hearing a voice that said, ';Look out the window and open it.'; I looked at the window and I saw about 12 tiny gray faces. They looked something like Planet Of The Apes. They were all stacked on each other, as if they were all trying to get a look in through the window. I wrote this off as an optical illusion. Last year though, I saw some special on UFOs and the like on Discovery. They pictured the SAME tiny creatures as my ';incident.'; I was a little more than freaked...
I've seen UFOs four times, but definitely don't believe we're being visitted by extraterrestrials.
Nobody has ever seen a flying object made by an extraterrestrial civilization. People have only seen things they couldn't properly identify. The most ';famous'; UFO sitings can be easily explained with natural phenomena (especially reflections on canopies, rare atmospheric effects and similar).
The UFO myth simply continues to live on because the natural explanation does not fit many people's sense (and sensibility) for the super-natural. And if one wants to believe that there is something out there, any explanation will be better than the one that clearly says that there was nothing out there.
The easiest ';laugh test'; is this: the total number of picture recording devices has probably increased 100-1000 fold over the last 50 years. And the quality of those images taken by digital equipment have also increased greatly. Nobody except for very few professional photographers had a camera lens similar to the 10:1 zoom found in most $200 digital cameras today. So if UFOs were a real phenomenon, documented events should have increased by the same number and there should have been images with MUCH better quality become available than ever. But nothing like that has happened. Unless the extraterrestrials have vanished into thin air just as we developed digital cameras, there never were any.

An object with a mass of 78 kilograms is lifted through a height of 6 meters . How much work is done?
First calculate force.
F = a*m = 9.8*78 = 764.4 kg*m/s^2
Now calculate work.
W = Fd = 764.4 * 6 = 4586.4 kg*m^2/s^2
Convert units.
1 kg*m^2/s^2 = 1 joule, so
4586.4 kg*m^2/s^2 = 4586.4 jouleAn object with a mass of 78 kilograms is lifted through a height of 6 meters . How much work is done?

What is the temperature an object can reach that will be the same in Celsius and in Fahrenheit ?
from ur question...
C=5/9(F-32)
C=F
answer.
F=5/9F-160/9
4/9F=-160/9
4F=-160
F= -40
the answer is -40What is the temperature an object can reach that will be the same in Celsius and in Fahrenheit ?
-40What is the temperature an object can reach that will be the same in Celsius and in Fahrenheit ?
hey its more of a quiz question %26amp; it has become very common
we generally use tis formula,and coz the temp is same in celcius as well as farenheit we can replace c by f or vice versa
(f-32) = 9c/5
f-32= 9f/5
-32= 9f/5 - 5f/5
-32= 4f/5
-32*(5/4)=f
-40=f
(f-32) = 9c/5
f-32= 9f/5
-32= 9f/5 - 5f/5
-32= 4f/5
-32*(5/4)=f
-40=f
-40
-40 C = -40 F
-40
The equation you listed is the relationship between a Fahrenheit temperature, represented by ';F,'; and the corresponding Celsius (or centigrade) temperature, ';C.';
C = 5(F-32)/9
We want to find the value where F and C are the same -- in other words, F=C. But since F=C, any place we see the C variable, we can replace it with (or ';substitute';) the F. That gives us:
F = 5(F-32)/9
Now we just have to solve this for F. We start by multiplying both sides by 9:
9F = 5(F-32)
Using the distributive property on the right-hand side,
9F = 5F - 160
Subtracting 5F from both sides gives
4F = -160
And, finally, we divide both sides by 4:
F = -40
And since C = F, C = -40, too.
Let's test our answer. The original equation was:
C = 5(F-32)/9
If we evaluate this equation when C = -40 and F = -40, do we get a true statement? Let's find out:
-40 = 5(-40-32)/9
We simplify inside the parentheses first: -40-32 = -72
-40 = 5(-72)/9
Next, 5*(-72) = -360
-40 = -360/9
And -360/9 = -40
-40 = -40
That's certainly a true statement, which means we found a correct solution.
Hope that helps!

Can the velocity of an object be negative when its acceleration is positve?
Sure. Define DOWN as positive.
Gravity (acceleration) is positive.
I throw a ball in the air.
Velocity is negative and acceleration is positive.
This occures whenever the direction of motion is opposed to the force.
-FredCan the velocity of an object be negative when its acceleration is positve?
Yes, the velocity can be negative when the acceleration is positive.
Conceptually, if you take the direction of going ';right'; positive, then going ';left'; is negative. The object can be accelerating positively towards the ';left'; or ';negative velocity'; direction.
Also, a velocity of an object that is negative only specifies the direction. Acceleration is the change in magnitude OR direction OR both of an object's velocity. Therefore, it is true.Can the velocity of an object be negative when its acceleration is positve?
yes, velocity is speed in a given direction. If the object is traveling in the opposite direction in a relative plane of motion, it might be considered to be moving in a negative direction (relative to the positive direction.
Certainly, just swap the signs around.
A positive velocity can decelerate (Have a negative acceleration), just think of it as driving a car in reverse and applying the brakes which brings the negative velocity back to 0 ( which is positive)

contact the company of the food product and let them know. They should refund your money or send you a new product.
Send the package, the foreign object, and your sales receipt back to the manufacturer for a full refund. Include a short, polite letter requesting same.
take it back to the store and get a replacement or you could sue the company if they don't comply. Just giving you options. Good Luck

I am almost certain that there is a phone number in the package to call with coments or question..
You can either call, write or go to the website and explain your concern...Make sure you can provide the code numbers printed on the package..
Companies always welcome problems like this so they can be avoid in the future.

I once found an item in my food. I taped it to an index card (it was a bone shard), and sent it and the manufacturing code from the box, along with a POLITE note, sharing my experience and noting my concern for other consumers and the company's reputation. I received a check for about $10, some coupons for future purchases and a polite response. By not threatening them, I got a positive response. I didn't act like I was shaking them down. Now, if you want to shake them down, you should try to find all the original packaging, possibly the grocery store receipt and contact a lawyer. Good luck, hope you are ok!
There's always a number you can call that's listed on the packaging. Definitely call that- the company needs to be aware of its fault.
You can probably return the item for a full refund wherever you bought it, if you still have the receipt and if you want to.
that's what happened to my aunt. she found this gross greasy nail in a package of 100 calorie chips ahoy. i think she just sent a letter to the company with a picture and they sent her some coupons or something.
If it was a boxed product call the 1-800 number on the back or bottom for consumer report. Save the box in case they want you to send it in.
If it was at a resurant of some kind take it back, talk to a manger, and ask for the for a customer complaint number.
Remember companies can't fix what they don't know is wrong.

Why does a three-dimensional object consisting of regular pentagons have twelve surfaces?
I know because I constructed one, but I'd really like to know why.Why does a three-dimensional object consisting of regular pentagons have twelve surfaces?
Suppose that you are trying to make a solid with n pentagons. These will have a total of 5n sides but when you put them together you join pairs of sides to make an edge of the solid so it will have 5n/2 edges. The n pentaongs will have a total of 5n corners but when they are joined to make a solid three will combine at one vertex of the solid so it will have 5n/3 vertices. (You know that three must combine at a vertex because two would not make 360 deg. and four or more can't join together in the way that you want.) The n pentagons of course make the n faces of the solid.
If you put these figures into Euler's equation F + V - E = 2 mentioned above you get n + 5n/3 - 5n/2 = 2. When you solve this equation you get n = 12.Why does a three-dimensional object consisting of regular pentagons have twelve surfaces?
The same reason a square has six! Good question. But Sorry I haven't got a clue.
first, i don't know. but maybe this would be a place to start.
but, first we might look at a 3 dimensional object made out of triangles.
it can have, 4, or 8, or 20 sides.
and if it's squares, then it's 6 sides.
but back to triangles.
if the corner angles (in 1 vertex) add up to:
180, there's 4 sides.
240, there's 8 sides.
300, there's 20 sides.
for reference, 270=6, and 324=12 so we need to confine any analysis to triangles.
Not sure. All I know is that it's called a dodecahedron, and I'm not sure if it's spelt correctly.
It has to do with a formula (found by Euler), that, for any regular polyhedron F + V - E = 2, where F = faces, V = vertices, and E = edges. From that there is a way to prove that the number of sides for a polyhedron with three pentagons at each vertex must be 12. Unfortunately, I can't remember how that proof is done, but I'll bet someone here does...
* * * *
OK, thinking about this, I think it is all coming back to me. You need three more ratios to solve this.
First, the face vs edge ratio. Since you have only pentagons, each face has five edges, while each edge is part of two faces. So, E/F = 5/2.
Next, the edge vs vertex ratio. Since there are three faces meeting at each vertex, each vertex has three edges, while each edge has two vertices. So, E/V = 3/2.
Lastly, the face vs vertex ratio. Each vertex has three edges and each face has five vertices. So, F/V = 3/5.
Add Euler's equation to this, and you have a uniquely solvable system of equations: F= 12, V = 20, and E = 30.
Suppose that you are trying to make a solid with n pentagons. These will have a total of 5n sides but when you put them together you join pairs of sides to make an edge of the solid so it will have 5n/2 edges. The n pentaongs will have a total of 5n corners but when they are joined to make a solid three will combine at one vertex of the solid so it will have 5n/3 vertices.

Need help finding the net rate of emission of radion of the object?
A spherical object of radius 0.1 m and emissivity 0.4 is at a temperature of 75 degree celcius. Its environment is at a temperature of 13 degree celcius. Calculate the net rate of emission of radiation of the object.Need help finding the net rate of emission of radion of the object?
If 75C is temperature of the outer surface, then deltaT between the surface and the surroundings is 62K .
Net rate of emission = (5.6704 x 10^-8 W/m^2.K^4) (0.4) 4(pi)(r^2) (deltaT^4)
Radiation emission = (2.26816 x 10^-8 W/m^2.K^4) (12.57 cm^2) (10^-4m^2/1cm^2) (63K^4)
Rad emission = 0.5642 Watts
Edit:
If the heat is 75C on the surface, then in the center of mass it will be:
Peak central temperature = (0.5642 Watts) (0.1m) / (Thermal conductivity of sphere material) (12.6cm^2) + 75C
PCT = 75C + 0.04478(k)
k = thermal conductivity
So if it was:
(Materal / Peak Central Temperature)
Lead / 76.6C
Iron / 78C
Copper / 93C
Helium balloon / 75.007C
Glass / 75.048C
If 75C is temperature of the outer surface, then deltaT between the surface and the surroundings is 62K .
Net rate of emission = (5.6704 x 10^-8 W/m^2.K^4) (0.4) 4(pi)(r^2) (deltaT^4)
Radiation emission = (2.26816 x 10^-8 W/m^2.K^4) (12.57 cm^2) (10^-4m^2/1cm^2) (63K^4)
Rad emission = 0.5642 Watts
Edit:
If the heat is 75C on the surface, then in the center of mass it will be:
Peak central temperature = (0.5642 Watts) (0.1m) / (Thermal conductivity of sphere material) (12.6cm^2) + 75C
PCT = 75C + 0.04478(k)

Is terminal velocity the highest velocity that a falling object can reach?
Can somebody answer me a few questions?
True of False
1Terminal velocity is the ??';highest';?? velocity that a falling object can reach.
2.Air resistance acts in the ??';opposite';?? direction to that of an object in motion.
3. Microwelds are the source of ?';momentum';?? between two surfaces pressed together.
4Anything that is thrown or shot through the air is ??';weightless';??.
If i'm wrong on any of these please correct me.
Thanks =)Is terminal velocity the highest velocity that a falling object can reach?
1. Terminal velocity is when air resistance and the object's speed due to gravity are equal. Therefore terminal velocity changes at different altitudes and planets.
2. Correct
3. Microwelding is a technique used to weld two really small things together, I don't get how it can be a source of something, rephrase the question?
4. Only things that are falling at their terminal velocity are weightless. Things going downward at a speed below terminal velocity have a slightly lower weight than when they are at rest and things going upward away from the gravitational pull are heavier.

If an object is propelled straight upward from ground level with an initial velocity of 48?
its height ft per second, h in feet t seconds labor is given by the equation h=16t^2+48t After how many seconds is the height 32 ft?If an object is propelled straight upward from ground level with an initial velocity of 48?
Set h = 32, so 32 = 16t^2 + 48t. Solve this quadratic equation for t.
You can make the equation a little easier to work with by dividing both sides by 16.
32/16 = (16/16)t^2 + (48/16)t
2 = t^2 + 3t
However, that equation is incorrect. The correct equation is h = -16t^2 + 48
You'll get two answers. Both are correct. One is when the ball is on the way up, the other when it's on the way down.

Does an object speed up, slow down, or remain the same during the 0.50 s time interval?
does an object speed up, slow down, or remain the same during the 0.50 s time interval?Does an object speed up, slow down, or remain the same during the 0.50 s time interval?
That depends on what the object's acceleration is.Does an object speed up, slow down, or remain the same during the 0.50 s time interval?
Newton's 1st Law of Motion: an object in motion will stay in motion unless acted upon by a force. By analogy, force = mass*acceleration.
If there is a force acting on the object, then it will speed or slow depending if it's in the direction of travel or not.
If there is no force acting, then it will stay the same.
You aren't specific enough. I need more information. If you showed me a diagram or something, I could figure it out. YOu have to be more specific.
Why not ask a proper question? Where's the rest of the information?
does it hit a wall after .50s or run into an elephant? we need info to help you buddy

Given an object that is denser than water, how will you make it float?
given an object that is denser than water, how will you make it float in water?Given an object that is denser than water, how will you make it float?
Any object that enters a fluid will displace some of the fluid. A totally submerged object will displace its own volume. A floating object will displace a volume less than its own
volume!
Any object submerged in a fluid experiences a buoyant force. This is true for both floating objects and submerged objects.
In all cases, the buoyant force on an object is equal to the weight of the displaced fluid.
For floating objects, the buoyant force is equal to the object's weight.
For submerged objects, the buoyant force is less than the object's weight.
Weight = mass x gravity
gravity = 9.8 m/s^2
density = mass / volume
specific gravity = density / (density of water)
density of water = 1.00 g/cm^3 = 1000 kg/m^3
Or try this fun link that has drawings explaining it (its really cool)
http://www.physics.mun.ca/~jjerrett/buoy鈥?/a>Given an object that is denser than water, how will you make it float?
lower its density by forming it into a boat like shape.
Steel is much denser than water, but when formed into a baot, it will float. This is becasue the apparent volume of the steel has lots of empty space in it. This empty space added to the volume of the actual steel, make the density lower than 1....therefore, it will float.
increase the water's pressure
Decrease mass per volume (m/v) by adding that mass to a higher volume (say, a boat) or increase the mass/volume of water, by adding mass to the water, increasing its density (say, by adding salt to it). The idea is to get the total mass per volume of your object to equal the mass/volume of water.
(Note, the volumes of your immersed object and the displaced water volume are equal, but the mass per that volume can change).
Change the shape of the object so that it displaces more water than the object weighs. Like a boat.
Give it a large enough surface area.
change its molecular structure so it will float
Put it on a boat.
Add salt to the water.
add a powder to the water that will make the water denser

Why am I only viewed as a sexual object?
it's hard to find a guy that doesn't want nothing less then friends with benefits. I've had at least 8 guys within the past year hint me that they want some....But I've never given it to anyone.
Couldit be that their just guys? and will hit on anything??
their all guys at work. They just want to hit it...and I really don't talk to them much really.Why am I only viewed as a sexual object?
Maybe cos you call yourself yummy?
Is it not that you secretly revel in the attention? Calling yourself yummy certainly seems to be a cry for some form of sexual attention.
And of course blokes are mad for it, thats what we do! If your in the least bit flirtatious men will hit on you. It could be viewed as a compliment you knowWhy am I only viewed as a sexual object?
so if all of a sudden no guys gave you a second look or ever flirted with you, you would be more happy? somehow i don't think so.
its got to be annoying getting hit on by EVERY guy you spend more than 5 minutes with, but you can stop it if you really want to bad enough. for starters don't let people call you yummy. earn and command respect 100% of the time, no breaks or exceptions. and be prepared to have a smaller # of good friends instead of lots of shallow ones.
Well let's see. You go by the name of 'Yummy', could that be part of the problem? I hate to ask this but how do you dress? I too have had plenty of male admirer's over the years but I was always treated like a lady at the same time. Men may have noticed my blonde hair or breasts first but I was always quick to show them my brains and that I was to be taken seriously. I also never dated (or had anything to do with) men my own age, I always dated men who were a bit older and more mature. Younger men have a tendency to have only one thing on their brain, the brain in their pants. Good luck!
They really aren't real men. I don't know why some guys try to be disgusting and perverted. Talk to them and tell them that you don't feel comfortable with their actions towards you. If they act like jackasses again then just ignore them. Not all guys are like this. I have a couple of guy friends and they are the best!!
Just ignore them!
When guys act immature like that just ignore them, bluntly show to them you're not interested. Eventually they'll get the message.
If it's at work and they verbally abuse you in that way constantly, you could talk to your boss about it.
Hope you find someone who respects you =)
i feel the same way.
im viewed as a sex symbol, people think thats the only thing im good at.
and everytime i like a guy, he acts like he likes me, but truth is that he just wants to **** and move on.
idk whats up with guys these days not wanting relationships.

Actually It matters on the amount of gravity it has compared to earth. If it has 1/2 of Earths gravity then the obJect weighs 200N. You have to multiply the mass of the object by the amount of gravity it has compared to earth.

What is gravity? What physical porperty of an object is the main determintation of its gravity?
The gravitational field of an object is based on its mass. Don't confuse this with weight. We would weigh different amounts on different bodies because of the different gravitational fields. For example, the gravitational field of the moon is roughly 1/6 that of the earth's so we would weigh about 1/6 as much on the moon as we do here on earth.
Distance also affects the gravitational field. The closer you are to something the stronger the effect of gravity. In fact the force of gravity is proportional to the square of the distance between the objects. So if you triple the distance between 2 objects, their gravitational pull on each other weakens 3虏 = 9 times.What is gravity? What physical porperty of an object is the main determintation of its gravity?
Gravity is a field, a mathematical law that describes how a mass in the field would respond.
Mass creates gravity, and gravity causes mass to move.

Can an object obtain a larger impulse from a smaller force than from a larger force? Explain?
It depends on how long the force is applied. Impulse is the area under the Force-vs-time curve. If a small force is applied over a very long time span, the impulse may be quite large. Conversely, if a LARGE force is applied over a tiny amount of time, the impulse may be relatively small.
If you want to compare the impulses when both forces are applied over the same time span, the answer is, of course, that the larger force will yield the larger impulse.Can an object obtain a larger impulse from a smaller force than from a larger force? Explain?
To try and keep it apples to apples and oranges to oranges, this only thing I can think of;
Say you put a 32.2 pound ball on the floor. The force at the point of contact is 32.2 pounds force.
The mass of the ball is 32.2 / 32.2 = 1 pound mass (slug) (since gravity is 32.2 ft/s/s)
Now you use a 1/2 pound mass ball at same size. In order to keep the same force, since F = ma, 32.2 = 1/2 a, so now use an acceleration of 64.4 ft/s/s.
The force is still the same put the impulse is twice as large.
If you were lying on the floor, would you rather have the 32.2 pound ball sitting on your chest, or have a 16.1 pound ball hit you in the chest at 32.2 feet/s/s?Can an object obtain a larger impulse from a smaller force than from a larger force? Explain?
He's right.
The concept of a solar sail, for example. They use the tiny ammount of pressure applied to something by the light bouncing off it to gain speed. This is slow, but unlike rockets or anything else, it doesn't require fule and will continue to gain impulse as long as the sun is shooting photons and the sail is deployed. Hypotheticaly, this could be used to approch lightspeeds, where rockets wouldn't have a chance at that.

How fast must an object be moving before it becomes imperceptible to humans (pt 2)?
Alright, lets try again with more detail. The object in motion is roughly the size of an adult male human, and the distance from the observer is roughly 5000 feet.How fast must an object be moving before it becomes imperceptible to humans (pt 2)?
5000ft is nearly a mile, I doubt you could even see a stationary person at that distance.How fast must an object be moving before it becomes imperceptible to humans (pt 2)?
You would have a hard time seeing a person standing 5000 feet away. If he was moving, he would be easier to see, not harder. For something that big to be imperceptible, it would have to be moving impossibly fast, like ten thousand feet per second, or maybe more. It would have to fly across your field of vision in a fraction of a second, and your field of vision would be around 5000 ft. wide.
Think of a guided missile the size of a man, flying at 3000 ft/sec. (Assume there is no contrail.) Would you see it at 5000 ft? You should if you are looking in the right direction, although you would only see it for a second or two.
Ok, it seems the resolution of the human eye in good light is about 81MP or 1.6 minutes of arc. (0.027 degrees). A two-foot wide person standing 5,000 feet away would be about .022 degrees, (2*arcTan(1/5000)) so it would be difficult already.
Temporally, the maximum flicker rate we see is something like 75Hz, or 0.0133 seconds. So you could guess that something that passes your entire field of vision in less than 0.0133 seconds might go unnoticed, but your field of vision is a tad more than 180 degrees, so you would see anything travelling in a straight line fade into the distance.
So here's a guess - 120 degrees view in 0.0133 seconds, so something circling your head a 9022deg/sec, or 1,504rpm shouldn't be visible at any distance. But you might still feel and hear it. At that rate, it would break the sound barrier at 27 inches away or more - my guess is you would hear that.
This question has a lot of variability. If the object is about a mile away it would be difficult to observe standing still. I would imagine a motorcycle on a highway a mile away traveling 70 mph would have a good to fair observability. Twice that speed fair to poor. I will take an educated guess and say 400 - 500 mph, maybe even more. It really depends on the surrounding and the amount of light reflected from the object.
5000ft is nearly a mile, I doubt you could even see a stationary person at that distance.How fast must an object be moving before it becomes imperceptible to humans (pt 2)?
You would have a hard time seeing a person standing 5000 feet away. If he was moving, he would be easier to see, not harder. For something that big to be imperceptible, it would have to be moving impossibly fast, like ten thousand feet per second, or maybe more. It would have to fly across your field of vision in a fraction of a second, and your field of vision would be around 5000 ft. wide.
Think of a guided missile the size of a man, flying at 3000 ft/sec. (Assume there is no contrail.) Would you see it at 5000 ft? You should if you are looking in the right direction, although you would only see it for a second or two.
Ok, it seems the resolution of the human eye in good light is about 81MP or 1.6 minutes of arc. (0.027 degrees). A two-foot wide person standing 5,000 feet away would be about .022 degrees, (2*arcTan(1/5000)) so it would be difficult already.

IF two objects move at light speed towards one another and another object?
hits them when they collide, do these objects fuse together?IF two objects move at light speed towards one another and another object?
It's impossible for any object to move at the speed of light, so that part is meaningless.
But take that as 99% of the speed of light, which is remotely possible. Due to relativity, the perceived speed seen from the first object to the second one is still less than the speed of light, it is 99% of c.
When they hit, there will be a large amount of energy released, and that can be calculated. Probably enough to turn them both into vapor, so the ';fuse together'; is meaningless.
.IF two objects move at light speed towards one another and another object?
Last time I checked this was theoretically impossible.
Due to relativity, if an object is moving at the speed of light towards another object traveling at the speed of light, then ';relatively speaking'; the 2nd object is moving towards the first at twice the speed of light, which is supposedly impossible.
Then you throw in the complication of energy requirements of actually getting an object to accelerate to the speed of light.
Also, with relativistic mass increase and length contraction. You have the problem of both objects having infinite mass, and infinitesimally short.
I don't understand where the ';Fusing'; would come into it....
So I would say .... NO!
I suppose to add to it, you could be talking about photons, which can travel at c, since they have zero mass, but how would 2 objects of zero mass fuse together....? what is there to fuse....?
Yeah, I'm sticking with ';No';
Are you asking, what happened when three objects traveling at the speed of light collide together? First what are the objects? Remember nothing can travel as fast as light, only mass less objects can “photons”. But objects in our experiment have mass and let’s say traveling at 99.99 % the speed of light, ok. The amount of energy that would be released at the moment of impact would completely destroy vertically all the mass in the objects converted in to pure energy. Some may form very heavy particles.

How much will this object be moved by this force?
This is all hypothetical. I am writing a paper about rifles and need to consider the effect of air density and wind speed on the displacement of a bullet. For the purposes of the calculation, I'm using 7.62 x 51 mm NATO bullet, which weighs approximately 9.5 grams. I am also going to hypothetically assume that the bullet is a perfect cylinder, in which case it would have a surface area of 1312.09 mm^2. In an assumed scenario of sea level at 20 degrees Celsius, the force exerted by a 1 meter per hour wind would approximately be 1.21528 x 10^-10 Newtons.
First of all, someone tell me if that's correct.
Next, can anyone tell me how I can determine what distance the wind will push the bullet?How much will this object be moved by this force?
I have never actually seen a calculation for the deflection of a bullet assuming that the bullet is a cylinder. Normally, the calculation is performed using a parameter called the ballistic coefficient (BC). See reference 1 below.
There are two ways that I have seen people use to model bullet motion in wind:
a) relative motion argument (see reference 2 for more details)
b) gyroscopic argument (see reference 3 for more details)
Both methods give similar answers, but the relative motion argument is conceptually simpler. For a nice summary of all the physical effects on a bullet, see reference 4.
Now let's look at your solution. Reference 1 gives examples of the typical wind deflections for bullets. Let's do an order of magnitude calculation. A 7.62 NATO round will have approximately 0.67 inches of deflection at 100 yards for a 10 mile per hour wind (assuming one minute of angle [MOA] equals one inch at 100 yards). Since this round has muzzle velocity of 2500 feet per second ( 762 meters/second), the round will take 0.12 seconds to hit the target. Assuming a constant force on a bullet with constant mass, the acceleration of the bullet can be calculated as follows.
d = 1/2*a*t^2 =%26gt; a = 2.364*m/sec^2
fWind= ma = 0.022N, which is much greater than the force you list. Of course, I am assuming a 10 mile per hour wind. A 1 meter per hour wind is very low (did you mean 1 meter per second?). So I do not believe that your answer is correct.
To calculate the force on a bullet, I would use one of the references below (like Reference 2) to estimate the effective crosswind induced angle or velocity. Then I would compute the effective force using the method I used above.
Wish I had a better solution for you.How much will this object be moved by this force?
I agree with you that intuitively the effect of wind, and air density would affect the trajectory of a bullet. Drag force opposes motion, and would be higher with higher density fluid. For example shooting a bullet into water would affect the path of the bullet more than it would in air.
I would use fluid mechanics to estimate the drag on the bullet. The general formula for drag is:
Drag Force = Cd * Area * fluid density * velocity^2 / 2
If the wind has a component opposing forward motion (i.e. across the target line), this drag force will be imbalanced and cause acceleration which will push the bullet offline. The higher the air density, the higher the drag and larger the offline force.

What would happen if you accidently transformed into an inanimate object?
Make a story of what would happen if you were transformed into an inanimate object. Like if you wished you were athletic and was turned into a jersey and was worn by your best friend who you could communicate with or I you wanted to own a car and was transformed into a car.
What interesting stories would you have I would like to read them.
Please nothing that involves sex.What would happen if you accidently transformed into an inanimate object?
One day, as I was searching through an old antique store, I came upon an old red clay jar with a blue glass stopper. It was plain to behold, but I felt compelled to buy it none the less.
After I purchased the jar, for an appalling $29.95 I might add, I took it back to my lonely apartment. I placed the jar on the mantel of my fireplace. It looked odd in the empty living room. I noted it would have match my burnt sienna leather couch perfectly, if I still had it. Sadly, my ex-husband took even that.
Being the only object in the room, I studied the jar intently. The blue glass stopper twinkled in the light, catching my eye and drawing me closer. I reached for the jar and uncorked it. Smoke and ash filled the air.
I dropped the jar, and blinked rapidly, trying to clear the soot like material from my eyes. My eyes began to water, making it difficult to see. Through blurry vision, I saw that the smoke was congealing. I used my fingertips to rub my eyes clear, and I wish I hadn't. Before me, a gray face floated in the air, filling the room. I gasped. My legs gave out and I collasped.
The face remained indifferent, if not unsympathetic, to the fear I felt of it. ';One wish,'; a voice boomed around me. The lips on the face did not move, yet I knew it was this face of ash and smoke that spoke.
My mind reeled. What did it mean. One wish? I wanted to ask the face what it meant, but I could not find my voice. I looked down, no longer able to gaze at the apparition. My eyes found the jar, which laid near me, unassuming despite what just escaped from it. ';One wish,'; the voice repeated again. I cringed. I just wanted the face to go away.
Somewhere in my mind, a thought connected with another, and familiarity set in. ';One wish.';
Yes, I knew this story. I looked up to the face. ';I wish I was loved, unconditional,'; I whispered.
The face dissolved into a cloud. It began swirling around me. Faster and faster it went until I could see naught but grey. Then there was light. It was fluorescent.
I sat in a store, gazing out into an asile of toys . I was small, and furry. A little girl came running up and pulled me off the shelf. She hugged me tight and said, ';I want this one mommy.';
I cursed the genie that made me a teddybear. After all, I would only be loved as long as the little girl was little. Then I would end up in a box with other forgotten toys, collecting dust in the attic. Or worse yet, I would be thrown in the trashbin, not even worthy enough to take up attic space.
But the genie was true to his word. I became the best friend to this little girl. We played tea, we watched movies together. We went for walks, she pushed me in her baby carriage. She slept with me everynight, and took me everywhere she went, when she could.
Even when the little girl became a teen, I held a place of honor on her bed. She held me tight and cried herself to sleep when her first love broke her heart. She whispered her secrets to me, knowing I would keep them.
One day, she donned her graduation gown, and I knew for sure this would be the end of our relationship. She was too old to bother with the likes of me anymore. However, she shoved me into her suitcase when she left for college. And dorm life was exciting.
She put me next to the pillow on her new bed in her new apartment. The days passed and I watched her blossom into a beautiful women. One morning, she dressed in a lovely white gown. Soon after, another moved in, a handsome man, kind and gentle. She placed me on a shelf in her bedroom and there I remained for months as I watched her grow rounder and rounder.
When took me off the shelf, she placed me in a white crib. A little baby girl slept there.
And that baby girl grew and we had many adventures together, until she had a baby girl of her own.

What happens if an object absorbs all light?
It looks black. When something absorbs all wavelengths of light t appears black.What happens if an object absorbs all light?
I believe it turns the color blackWhat happens if an object absorbs all light?
The colour of the Object is not contained within the object.The colour is the result of the light which strikes the object and is reflected by it.
When visible light strikes an object and a specific frequency becomes absorbed, that frequency of light will never make it to our eyes.
Any visible light which strikes the object and becomes reflected or transmitted to our eyes will contribute to the color appearance of that object.
Assuming that it absorbs light with 100 percent efficiency, it would glow as it gets hotter, and eventually would be vaporized by the heat involoved. Black holes of course do this and are invisible. But there is a side effect of this called the accretion disk. Its the visible part of the black hole where matter is annihalated and energy results in the form of gamma rays. But yes it would be black, if it didnt absorb anything else.
It would appear black.
It will be perfectly black
You would not be able to see it.
it appears black...cause it does not reflect any light
There are all sorts of wavelengths of light but if you're talking about absorbing ALL light, then I think you would have to be talking about a black hole. A black hole has a gravitational field so strong that nothing, not even light, can escape. Time is affected as well. There has been one discovered fairly recently in the constellation of Cygnus.
Truly understanding a black hole is beyond me but it's fun brain bubblegum as much of it is based on Einstein's Theory of Relativity.
I'm sure someone with more knowledge than I have will come along eventually to give a really good answer. It will be fun to read it.
Good question, btw! :)
Firstly there is no such object which obsorb all light.!
If we assume so.
1) no light will reflect from that object.
2) so will not able to see that object
3) if ther is no light it should be dark so it should be look as black
It's black.

How do I find the acceleration of an object, when only given the angle of the slope the object is on.?
Draw a free-body diagram. Straight down should be the force of gravity, then perpendicular to the slope should be the normal force. Set your coordinate axes in the direction of acceleration. So for the force sums, you'll get in one direction (call it x, the direction of acceleration):
Fx(total) = mgsin(theta) = ma
where theta is the angle. The mass cancels out, so a = gsin(theta)How do I find the acceleration of an object, when only given the angle of the slope the object is on.?
u time the speed of the object. stop it wen it the wheels reaches the end of the slope. the fomula of acceleration is acceleration= final velocity- initial velocity and the whole thing divided by the time. so in this case, the time= time it takes for the object to go down the slope.How do I find the acceleration of an object, when only given the angle of the slope the object is on.?
acceleration should only be gravity, unless other external forces are acting on it? gravity=9.81m/s^2

Is thermal radiation radiated ONLY from the SURFACE of an object ?
.. or is it radiated throughout the body ?Is thermal radiation radiated ONLY from the SURFACE of an object ?
generally speaking heat is not transmitted through the internal part of an object by radiation it is only radiated from the surface.
heat is transmitted through the internal part of the body by conduction. It is transmitted from the surface to other objects by either radiation, convection (through a moving fluid such as water or air), or conduction (by directly touching the other object).Is thermal radiation radiated ONLY from the SURFACE of an object ?
It is radiated throughout the body. The surface atoms are not the only ones that are involved in blackbody radiation.

What does it sound like when an ambulance with it's sirens on is not in motion& an object ismoving towards it?
i know about the doppler effect and the wave lengths when the ambulance is coming towards you or away from you but what about when it's stationary and another object is moving towards it or away from it? how does it sound and what is it's pitch?What does it sound like when an ambulance with it's sirens on is not in motion%26amp; an object ismoving towards it?
Great question!
Although this is rarely explained, the Doppler effect works even when the object emitting the sound waves is stationary! If you are moving towards the object at a constant speed, the sound, in this case the ambulance's sirens will be higher-pitched than normal.
When you pass it and start moving away, they will suddenly become lower-pitched.
What matters here is relative velocity. If there you and the object are moving apart or together -at any speed-, you will perceive the sound waves to be compressed or elongated, and you will hear an altered sound.
Great question!

That's true, the fact it is out of place will easily tell you and could easily be recognized because it is very obvious. Trying placing a red square on a group of blue circles. Isn't it grossly out of place? Indeed anything different from the group could easily be perceived by anyone.
Thanks to your question my friend. Have a great day!How easy is it to recognize an otherwise easily recognizable object, when it's grossly out of place?

What is the purpose of the round plastic ball like object that you see hanging out of electricity cables?
you see them hanging across road on wires that are coming from pylons.What is the purpose of the round plastic ball like object that you see hanging out of electricity cables?
I thought that maybe they were to make it easier to find the wires if they ever fall.What is the purpose of the round plastic ball like object that you see hanging out of electricity cables?
they are so pilots of small aircraft will see the wires and not fly into them
why RED Balls, because Santa flew into wires once and that was all that was left of him!
I thought it was so the wires couldn't touch together
Depends how far apart the cables are. Some birds have such a large wingspan that they could short between two cables so distractors are hung between them to discourage the birds from flying through
I have always believed they were markers to warn low-flying aircraft. Maybe not?
so that you can see the wires against the sky. an alert for airplanes, helicopters, etc.
Visibility.
It may be near a hospital or airport and it helps keep helicoptors from running into the wires.
Is it a light bulb?

Where do the various colors of light go when an object absorbs them instead of reflecting them?
Usually the energy of the light gets converted into mechanical vibration of the molecules, or in other words, heat.
Sometimes some of the light energy is harnessed to do work - such as by the chlorophyll in a plant's leaves or in a solar cell.Where do the various colors of light go when an object absorbs them instead of reflecting them?
Light radiation is one variant of electro-magnetic energy. When this radiation is absorbed by any object, the object gains that much energy as increased motion of its own atomic particles, i.e. increased heat usually, or increased energy level for the electrons within the atomic particles. The amount of energy thus absorbed by most objects is usually not very great, although ';laser'; action can occur when favourable wavelengths of light are absorbed within a medium such as a ruby crystal.Where do the various colors of light go when an object absorbs them instead of reflecting them?
They get turned into some other form of energy, most often heat. Whatever doesn't get absorbed, gets reflected.
The leaves of plants absorb red and blue light (which they turn into chemical energy), but reflect green light. Photovoltaic panels absorb (and convert to electricity) more blue light than they do red or green, so they appear sort of brown-ish (remember, brown is just very dim yellow or orange).
they are abosrbed by the electrons of the atoms. the energy dissipates by the electrons vibration.

I would say helium, because weight is a measure of gravities force on a mass, except you cannot see helium (atleast not in its true state). I believe the answer is indeed a whole. The questioneer here was thinking that when you see and object and a hole is in it, this observation alone is enough in most cases for you to know that hteres a hole, (i.e. you ';see the hole';. ) I agree you cannot see the actuall hole, only that the structure around it is missing a piece, but i dont think the person asking this question thought of it in that way.

Why is a measured amount of water needed to determine the specific heat of a metal object?
???Why is a measured amount of water needed to determine the specific heat of a metal object?
Because the heat energy absorbed or released by the water is dependent on the mass of the water.
q=m x c x delta T
The equation tells you that you need a mass, a specific heat and a change in temperature to figure out the specific heat of the metal.

On photoshop, how do you freely cut around an object in a picture?
kind of like cropping but doing it by yourself...like cutting with scissors. whats the button or tool that i can use?On photoshop, how do you freely cut around an object in a picture?
Use the magic lasso tool to trace around the objectOn photoshop, how do you freely cut around an object in a picture?
by using the Laso located on the tool bar(2nd tool on the left) hold the tool for couple of seconds then itll pop diffted lasos select 'magnetic laso' then just simply carve your image or something with it.
or by using path located on the layer palette. hit Path tab hit the triagle on the side then hit 'new paths...' then itll bring up a dark grey layer. Then you go back to your tool pallete select your pen tool(located 8th tool on the left side)
now using the Path tool requires knowledge of photoshop its not for beginners so very much doubt youll use it.... Using the 'magnetic laso' will be great for you.

An object is palced at a distance of 40 cm from the concave mirror of focal length18cm. What image is formed .
is it enlarged or diminished...expalin ur ans please !!An object is palced at a distance of 40 cm from the concave mirror of focal length18cm. What image is formed .
let the object distance=u= -40 cm
let the focal length =f= -18cm
[distances to the left are written with a negative sign]
let the image distance=v=?
BY the mirror formula,
1/f=1/v+1/u
=%26gt;1/f - 1/u=1/v
=%26gt;(1/-18) - (1/-40) =1/v
=%26gt;(1/40) - (1/18) =1/v
=%26gt;(9 - 20)/360 = 1/v
=%26gt; -360/11=v
=%26gt;v= -32.73 cm
the negative shows that the image is formed on the left hand side of the mirror and is real and inverted.
now,
magnification is -v/u
=33/-40
= -0.825
which shows that the image is 0.825 times the size of the object.
thus it is diminished.

If the reflected light coming off an object was in the spectrum of light invisible to me would it be?
visible or invisible?
Is it possible this is happening around us now?
Is it possible to create something that reflects light in this spectrum?If the reflected light coming off an object was in the spectrum of light invisible to me would it be?
Whether an object is visible or invisible depends on what it is doing only in the visible part of the spectrum. If it absorbs visible light, it will be black. If it passes visible light, it will be transparent.
Glass, for instance, which is highly absorbing in infrared, is transparent in the visible.If the reflected light coming off an object was in the spectrum of light invisible to me would it be?
It would depend on if the part of the light spectrum that was reflecting off of the object. If it's only reflecting say...UV, then it would be invisible to us, but if it reflected UV and a part of the visible spectrum we would see the visible part of the light that was reflected off of it.
It's perfectly possible that it's happening as we speak, I'm sure that there's many materials that reflect parts of the spectrum that are invisible to us. An example would be any metal object that shows up on radar. They reflect microwaves generated by the radar dish which allows the radar to see them. We can't see microwaves, but we can reflect them.
As for creating something that reflects only that part of the spectrum, that's something they still haven't figured out yet, as anything we make reflects part of the visible spectrum. If we made it reflect only part of the spectrum we can't see with our eyes then it would be the perfect camoflage, though unless the wearer of the material were to allow a little visible radiation in, it would be a double blind situation. The observer couldn't see the object, while the person wearing the material wouldn't be able to see the outside world.
I hope this answers your questions.
If the only light reflected by the object was in a range not visible to the human eye, the object would be invisible.
I doubt that it's happening, though, or we'd be bumping into invisible objects.
We do have objects that reflect invisible electromagnetic energy (and light is one small part of that spectrum). They are called ';dish antennas';. The dish reflects incoming radio waves back to the central antenna mounted above the dish, which converts the signal to electricity and sends it on to the TV. However, the dish also reflects visible light, so that the neighbors know that you can watch the big game when the cable is out.
The object would be visible but would appear to be black in color. If the background is also black, only then would it be invisible.
The dyes in photographic films are deliberately designed to absorb in certain ranges of the visible spectrum but to transmit in the infrared. When dyes of all three colors are present in large quantity, the film is opaque (black) to visible light but still clear to infrared. You can also buy filters for photographic use that block visible light but transmit infrared. Either of these could be backed with a reflector of infrared light to produce an object that reflects infrared but absorbs visible light.
';Hot'; and ';cold'; mirrors do not absorb any light to speak of but are deliberately manufactured to let visible light through and reflect infrared light (a ';hot'; mirror) or vice versa (a ';cold'; one). It would be no great trick to create an object that strongly reflected infrared but absorbed visible light by backing a ';hot'; mirror with a piece of black velvet to absorb the transmitted visible light.
Something like that happens with flowers whose colors are not limited to those humans can see. Bees, for example, can see into the ultraviolet part of the spectrum but are blind to red light. Some flowers, when photographed by ultraviolet light, reveal ';color'; patterns quite invisible to humans. Some birds see into both the infrared and ultraviolet as well as throughout the visible part of the spectrum. You can find flowers that these birds pollenate with patterns in the infrared that are also quite invisible to us.
This happens with ordinary lawn grass as well. We see grass as green, not black, but it also reflects very strongly in the near infrared. In an infrared photo, the foliage looks almost snow-covered but still retains its original texture.
Interesting! An object has substance whether or not you can see it. The Black Bird used by the US Air Force was invisible to humans below because of the use of light absorption. The spectrum of light is the color and there are many colors that we see only as shades of gray because they are outside the spectrum, but you can still see the object. A color blind person sees the object in shades of gray when he cannot see the color. Answer: Visible.

No Kira, your baby will not look like a dog. Your baby will look like a mixture of you and the baby's father. And no matter what s/he looks like, you will think you gave birth to an angel.Is it true that my baby will come out looking like the food or object i usually crave during my pregnancy?
I'm really hoping that you're just kidding! If my daughter had been born resembling the biggest crave I had while I was carrying her she would have looked like a stalk of celery with peanut butter on it. Or possibly a Sara Lee poundcake :)
Sure if you look like a dog
No way! No how! That is an old wive's tale! Your baby will be born looking the way GOD wants him or her to look!
Well, according to this, I expect I will give birth to a giant pizza very soon now..... :-D
no! that's just an old wive's tale!
I really doubt that your thought process during pregnancy has anything to do with the baby
A dog? No.

How do you put an object in your room in front or on top of an object on Zwinky?
On Zwinky, I tried to put like a lamp on my desk, but it went behind it and I also tried to put a ribbon thing on my coarkboard but it went behind it... please help!!!!How do you put an object in your room in front or on top of an object on Zwinky?
Zwinky needs to be removed as soon as possible. It is a malicious program that installs malware and spyware on your system. It is related to Smiley Central, MyWebSearch, and FunWebProduts, all sites that target younger people who will install anything. They should all be thrown in jail. You will need to install Malwarebytes and SUPERAntiSpyware to get rid of all of the malware you now have.
I'm sorry to ruin your fun, I'm just trying to protect you and your computer.How do you put an object in your room in front or on top of an object on Zwinky?
You need to uninstall all of the Zwinky stuff first, but if that works, and you can run Malwarebytes, your computer should be clean. Good luck to you! Report Abuse
It might not be too late. You could try restarting your computer, and right when it starts booting up, tap the f8 button a few times. You will see a black screen, just choose ';safe mode with networking';. Then try to get Malwarebytes from here:http://malwarebytes.org/. If that works, run a quick scan Report Abuse

An object is revolving in a vertical circle of radius 9.8 m, with a velocity which is just enough to make it ?
complete the loop. Find the
change in velocity of the object when it reaches from
position A to position C (AC is horizontal line
parallel to earth's surface)
An object is revolving in a vertical circle of radius 9.8 m, with a velocity which is just enough to make it ?
Fgravity down = M*A Where A = 9.8 m/s^2
Centripital Force = M (V^2/r)
At the top these balance
M*A = M*(V^2/r)
M cancels
9.8 - V^2/9.8
V^2 = 9.8 * 9.8 =
V=9.8 m/s

What are the objects in object oriented psychology?
They are inner conceptualizations of things a person experiences in their external life. Probably the most common example is a person's parent. Often a parent has many meanings to a person; if an individual is upset they may seek comfort and reassurance from one of their parents by being in their presence. However, sometimes the parent is unavailable in reality, so the individual can rely on the internal image (the internal object) of the mother to serve the same calming purposes. The person can ask themselves 'What would my parent say?' or recall a time with their parent that made them happy; this is relying on the object. In other words, an internal object is an representation of something experienced in reality.
