Don't worry, although I am slacker, I'm not asking anyone to do it for me. I'm already finished with it, I just need someone to read it over and make sure everything is correct. Also, I'm aware there are spelling errors, I'll correct them later.
Q. Under what condition will you and a friend share the same realm of spacetime?
A. Two people share the same realm of spacetime if they share the same reference frame.
Q. Time is required for light to travel along a path from one point to another. If this path is seen to be longer because of motion, what happens to the time it takes for light to travel this longer path?
A. The time it takes to travel the longer path legthens.
Q. If we see somebody's clock running slow due to relative motion, will they see our clocks running slow also? Or will they see our clocks running fast? Explain.
A. Both clocks will be seen as running slow because the measurements of one realm of spacetime need not agree with one another.
Q. If you were traveling in a high speed rocket ship, would meter sticks on board appear to you to be contracted? Defend your answer.
A. No. It only appears contracted outside of its relative time frame.
Q. If you were in a smooth-riding train with no windows, could you sense the difference between uniform motion and rest? Between accelerated motion and rest? Explain how you could do this with a bowl filled with water.
A. There would be no noticeable difference between uniform motion and rest. There would be a noticeable difference between accelerated motion and rest. In a bowl filled with water, it would remain even at rest and in uniform motion, but would tilt towards the back under accelerated motion.
Q. Can an electron beam sweep across the face of a cathode ray tube at a speed greater than the speed of light?
A. Yes, though the actual electrons will be moving at a speed slower than the speed of light. (I wonder if this concept has anything to do with why particles are appearing to move faster than the speed of light in the Hadron-collider experiments...)
