Physics - December 2007

I have an interdisciplinary project across the sciences and I am am working on the Chemistry and Physics aspects of it. My topic is toilets.

Sooo I needed a little help coming up with an experiment that would go under the category of either physics or chemistry. Physics is the main issue right now. Any help would be much appreciated!

For example, if there's a concentration of electric charge such that the escape speed for an oppositely charged test particle at a given distance is greater than the speed of light, does an event horizon exist for such particles?

Would like-charged particles get repelled so hard that they'd have a speed greater than c at infinity?

say I had a really long poll, say from here to the sun. If I move one end, would the other end move simultaneously? It was my understanding that nothing moves faster than light, so relaying a simultaneous message by moving the poll should be impossible. Is that correct? Why?

a fully dressed astronaut, weighing 1.2 x 10^3 N on earth is about to jump down from a space capsule that has just landed safely on Planet X. The drop to the surface of X is 2.8 m and the astronauts gravitational potential energy relative to the surface is 1.1 x 10^3 J.

a) what is the magnitude of the gravitational field strength on planet X.
b) how long does the jump take?
c) what is the astronauts maximum speed?

thanks for any help.......

and how do you convert 333660.6 J to scientific notation?

A coulomb is a very large unit of charge and is therefore very hard to obtain. However, fairly large currents of several amperes (coulombs/second) are very common. How is this possible?

switching action at time t=0.
In each case, how to I write the differential equation that must be solved to find the transient or natural circuit response?

dI(t)/dt + 6I(t) = 10

d^2I(t)/dt^2 + 5I(t) = 24

Many Thanks for your help :)
