· Point B represents a distance half-way down the ramp. If the ball rolls down the ramp, how much potential energy has been ...

The nuclear potential that binds protons and neutrons in the nucleus of an atom is often approximated by a square well. imagine a proton conned in an innite square well of length 105 nm, a typical nuclear diameter. calculate the wavelength and energy associated with the photon that is emitted when the proton undergoes a transition from the rst excited state (n 2) to the ground state (n 1). in what region of the electromagnetic spectrum does this wavelength belong?

Why does gravity have a lesser than grater effect on higher altitudes?

Which model displays the change in a gas when the temperature of the gaseous system decreases?
