14. (5 pts) The mean measured lifetime of an unstable particle at rest is 2.20 usec. If a sample of these particles is observed traveling at u = 0.95c, their mean measured lifetime will be 15. (5 pts) The work function of photoelectrode is 3.01 eV. Find the maximum velocity of photoelectrons ejected from this photoelectrode by 61 nanometer radiation. Give your answer in meters per second. 16. An electron in the hydrogen atom is in the 3p state. (a) (5 pts) Find the orbital angular momentum of the electron (in units of h). (b) (5 pts) Find the energy of the electron (in ev). (c) (5 pts) Ignoring electron spin, find the total number of quantum states that have this same energy. (d) (5 pts) Make a table listing the quantum numbers n, &, and m s of each of the degenerate states. Indicate the spectroscopic label (e.g. 1s, 2s, etc) that would apply to each state
