Note to players: two answers required. Monomials of these two quantities are symmetrized in the Weyl ordering rule. A closed line integral of one of these quantities with respect to the other must equal nh in the Wilson–Sommerfeld quantization condition; that expression also defines the actions in action-angle coordinates. The expectations of these two quantities (10[1])follow classical orbits according to Ehrenfest’s theorem. (10[2])In either of these quantities’ eigenbasis, the other’s operator is given by negative i-times-h-bar (10[3])times a partial (10[1])derivative. (10[1])Derivatives of the Hamiltonian with respect to these two quantities (10[1])appear in Hamilton’s equations. The product of the standard deviations of these two quantities is bounded (10[2])below by (10[1])h-bar (10[2])over 2 (10[1])according to (10[1])Heisenberg’s uncertainty principle. (10[1])For 10 points, give these two quantities symbolized x and p. (10[3]0[1])■END■
