Physics - January 2007

Please avoid going on religious tangents. I am not religious, i'm spiritual. And yes there's a big difference between the two.

Could there be practical uses for propulsion?
What about if they were magtically connected-like a monorail, and it was in space so there wopuld be no resistance?

I'm thinking of the mechanisms used to test g-forces on pilots, but instead, in a frisbee-like structure (like a space station), which is then surounded by another similar structure spinning alternately and accounting for the differences between the two structures to compensate for speed. Could there be practical uses for propulsion?

I want to do practice and extra problems on High school Physics, can you recommend me some websites?

Particularly on the topics of :

-Newton's Laws
-Vector Motion
-Forces
-Forces and motion in Two dimension
-Momentum and its conservation
-Universal Gravitation

Basically the Mechanics part of physics.

Thanks =D

I'm doing a science project and i have found out that gravity does afect heigt but i dont quite know how to explain it. I really would like know are there comparisons and/or differences between the two.

i connected the two-pins of an electric fan to a voltmeter. when i rotated its wings, it showed 200V AC at peak.when i touched the ends of the two-pins and rotated it, it gave shock. what can be done with the voltage generated? can this be used to light a bulb?? can this be used to charge a battery?
can this be converted to DC to light a 3V bulb used in torch??
please help

A monochromatic light source provides 5 W of light of wavlength 4.40 x 10 ^ -7 m

This light falls on a clean potassium surface and liberates 3.2 x 10 ^ 11 photoelectrons per second.

The photoelectrons are collected by an electrode just above the metal surface and the photoelectric current measured.

Charge of Electron = 1.60 X 10 ^ -19 C

Speed of Light In Vacuum = 3.00 x 10 ^ 8 m/s

Explain whether or not photoelectorns would be emitted if a 20W source operating at a wavelength of 6.00 x 10 ^ -7m were used to be used.

The threshold frequency is 5.46 x 10 ^ 14 Hz

The speed of each spacecraft is 0.5c relative to a neutral observer, who observes each spacecraft traveling towards each other from opposite directions, at 0.5c each relative to the observer.

As measured from the sending spacecraft, the wavelength of the beam being send is 500nm.

What is the wavelength as measured at the receiving spacecraft.
