Question

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 follow classical orbits according to Ehrenfest’s theorem. In either of these quantities’ eigenbasis, the other’s operator is given by negative i-times-h-bar times a partial derivative. 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[1])below by (10[1])h-bar over 2 according to (10[1])Heisenberg’s uncertainty principle. (10[1])For 10 points, give these two quantities symbolized x and p. (10[1])■END■

ANSWER: position AND momentum [or generalized coordinates AND generalized momenta; prompt on x or q for position and p for momentum until read]
