Consider the infinite cubical well, 0, oo, otherwise xa,0 y < a, 0 < z < a 0 v (r, y, ) where , y and z are three-dimensional cartesian coordinates, length unit a is a positive constant in (a) find the stationary states and the corresponding energies (b) list first 15 different energy values in order of increasing energy, that is, e, e2, . ej5. (c) mention the degeneracy of every energy value. note that the degeneracy of e14 is somewhat special. why is that?

If a small-diameter open glass tube is partially immersed in a vessel containing mercury, the surface of the mercury inside the tube will be a. lower than the mercury in the vessel, and shaped like the inside of a bowl. b. higher than the mercury in the vessel, and shaped like the inside of a bowl. c. lower than the mercury in the vessel, and shaped like the outside of an umbrella. d. higher than the mercury in the vessel, and shaped like the outside of an umbrella.
