Show that the radius of an orbit may be expressed as follows: R^3=((GM)/4*pi^2)T^2

Start with Newton's Law of Gravitation: F=(GMm)/R^2 (1) Since orbits are assumed to be circular recall the equation for centripetal force: F=(mv^2)/R (2) We can now equate these 2 forces due to them being...

Use band theory to explain the changes in the resistance of an intrinsic semiconductor as temper changes.

At low temperatures(0K), the conduction band is empty while the valence band if filled. As temperature increases, the electrons gain energy to go into the conduction band and leave positive holes in the v...
