The earth is constantly spinning on its axis, like you might spin a basketball on your finger. it is this spinning of the earth that causes

The slope of a velocity time graph over any interval of time gives the during that interval

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?
