What is the minimum thickness of a glycerin film (n = 1.47) on which light of wavelength 450 nm shines that results in constructive interference of the reflected light? assume the film is surrounded front and back by air (a)150 nm (b)76.5 nm (c)204 nm (d)102 nm

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?
