Unformatted text preview: 1. a.) The restimas energy Ea and the total relative energy E of three particles are expressed in terms of a side amount A: particle #(E (1) =A, E (1) =2A), Particle#2(E (2) =3A, E (2) =4A), Paricle #3=2A, E (3) =3A. Rank the particles according to i)Kinetic energy ii) Their Lorentz factor (greatest first) γ b.) In a photoelectric effect experiment a student reported the following observation: i)while using a blue light, no photoelectrons were observed but photoelectron were ditected using red light, ii) light intensity is halved, iii) Photoelectrons continue to be detected when one switched to a metal surface with a large work function, which observation(s) is (are) physically possible: c.) A hydrogen atom is in its third excited state. To what state (in terms of the quantum number n) should it jump to so that i) the atom emits light with halved possible wavelength, ii) the……. 2. One mole of an ideal monatomic gas starting at state A (Pa=200 kpa; Va=10L is isothermally expanded to a volume of 20L at state B. then, the gas is taken to state C by an isothermally expanded to a volume of 20L at state B....
