General and Special Relativity

That's the job of the battery or other power supply.

The water present in the watermelon will give the fruit moisture and will not allow the heat to react with it.

A non-relativistic particle is any particle not traveling at a speed close to the speed of light. This is not a property of particular type of particle; any particle may in general travel at any speed (below the speed of light).

An exception are particles which are massless such as photons and gluons, these MUST travel at the speed of light.

Acceleration = 0

Speed = constant

Distance = (speed) x (time)

You could hear any sounds generated within your moving environment, and you would be able to hear outside sounds generated from the front and up to certain angles to the side, depending on how far away their point of origin as you approach and pass (and there would be considerable dopplering), but you would not hear sounds generated from behind if they originate outside of your moving environment.

Nothing other than E=mc^2 is an equation, just like any other mathematical equation.

i dont no yaar.......................

e=mc^2
E=mc^2

It isn't truly a paradox. Here's the problem: A spaceship leaves earth for a trip at high relativistic velocity. Aboard is one twin, the other having remained on earth. The ship is moving away from earth at high speed, and returns to earth at high speed, therefore it's time is dilated, so the twin on the ship ages more slowly and should return to earth having aged less than his earthbound counterpart. However, from the perspective of the ship, it is the earth that is moving away at high velocity, and the earthbound twin should be the one aging more slowly. The paradox dissolves when the nature of each frame of reference is taken into account. The earth is an inertial frame of reference. The spaceship, since it must undergo several positive and negative accelerations to make the round trip, is a non-inertial frame. Only the viewpoint from the intertial frame is valid. The explanation is far too long and involved to go into here, but you will find one of the best and most detailed explanations in Paul Davies' book "About Time" on pages 62 to 65.

No. Monochromatic light (light of a single color) will pass through the prism without dispersing. White light disperses into its constituent colors as it passes through a prism, and we therefore observe the different colors emerging in a dispersal pattern as the light emerges from the opposite side of the prism. Since monochromatic light is made up of only one color, there are no colors to disperse, and so the beam of light passes through the prism coherently.

Yes and no. Depending on what you mean, he was born in Ulm, Germany and he moved a lot to other countries. For example, if you mean about the time he still called his European teacher Herr watshisface I forgot his name

Displacement is the straight line distance between two points. If the two points are a half a lap apart on a circular path then the straight line distance is the diameter of the circle; 350 m. What that means is that displacement describes only the relationship between end position and starting position, so the car stops at a point on the opposite side of the circle, 350m from the start. Displacement is not necessarily distance traveled. If the car had gone completely around the circle and stopped where it started, the displacement would be zero, even though it has traveled nearly 1100 m.

All objects fall universally with the same acceleration: 9.8 m/s squared.

Such a question is a philosophical one. Science is a matter of how things work. If a why question is answered, it is only secondary to a how.

To figure out the force of gravity between the earth and the moon, you need to use newton's equation of gravitational force, i.e. F=(G x m1 x m2)/r^2 Where F is the force of gravity, m1 and m2 are the masses of the two objects in question, r^2 is the distance between the two objects in question, squared (times itself), and G is the gravitational constant which has a value of 6.67 x 10^-11 m^3/kg s^2

So, the answer is [(6.67 x 10^-11 m^3/kg s^2) (5.9724 x 10^24 kg) (7.36 x 10^22 kg)] / ((3.844 x 10^8 m)^2) = 1.9842 x 10^20 N

Relativity is where you or something is in relation to something else. Two examples are 1. If you are sitting in a railway carriage and another train is standing next to you. You see that the other train is passing you as you move forward, when in fact it is the other train that is moving and not your train. 2. A train is comming along a track as you stand on the platform. It has to travel 200 meters before it comes to a stop. A man in a carriage walks the length of the carriage which is 25 meters long. As far at he is concerned he has only travelled 25 meters but you know he has travelled 200 meters. It is all relative my friend, all relative.

Albert Einstein was awarded the 1921 Nobel Prize for his discovery of the photo-electric effect.

Curiously enough this work, albeit significant, pales in comparison to his work on relativity and gravity. It is said, however, that the Nobel committee did not understand his theory of general relativity well enough, and therefore awarded the price for one of his 'lesser' contributions to science.

It says that the speed of light in a vacuum measured in any inertial frame of reference is equivalent to the speed of light in a vacuum measured in any other inertial frame of reference.

I believe that the most obvious observation of time dilation is in particle accelerators. The particles move so fast that different processes occur slower than when they are not moving, or moving much more slowly.Other than that, I understand that very precise experiments were also done with clocks, which were taken on moving airplanes.
