The temperature dependence of the surface tension of a liquid is given by gamma = gamma_0 (1 - t/t_c)^n where gamma_0 is constant for a given liquid, t/t_c is the reduced temperature, and n is a constant (=1.2 for liquids that are not highly associated). if the critical temperature of water (t_c) is 374.1 degree c, determine gamma_0 and n for water using the following data

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?
