Physics - June 2006

people say that only non informational things, like gama rays, can move faster than light. but, what if two masses , like comets, that were moving at near the speed of light, say 99%. if they sped past each other wouldn't it apear from one comet, that the other was going past the speed of light(obviously they wouldnt see each other pass but they could see each other coming) if they colided wouldnt the forces cause something to get launched at a speed greater than light?

A professor when I was in grad school once asked this question. Say you're in a spaceship in orbit near the horizon of supermassive black hole --- i.e. one which is large enough that tidal effects are negligible for you. (And say it's nonspinning.) You try to put your (spacesuit-shielded) fist in hole. What happens?

I suspect the best answer may be "you get bored, pull your hand back and go home because it seems to be taking forever for your hand to move inwards as far as your brain is concerned". But I'd like to see your comments! (Not for homework: just curious!)

I have 1 spring balance with me(k1). I suspend 10 kg. It shows 10kg.

So far so gud. No big Deal.

Now i suspend this arrangement to another spring(k2). Now both show 5kg.
Q. Why is this so. Y dont they give anyreading totalling to 10. y only 5 and 5.

Q. Why does it not happen that spring1(k1) show 10kg. and the other spring show (10+weight of spring1)
as if we draw fbd of 2nd spring it has 10kg weight and spring 1 below it.


i hope u got what im trying to ask

Was the Pope afraid we'd find out we don't need "god" to explain it? That could put the church out of business! See the article at http://www.foxnews.com/story/0,2933,199673,00.html, and don't answer unless you read the article!
