Evaluate the average of the square of the linear momentum of the quantum harmonic oscillator ⟨p2x⟩ for the ground state (n=0) and first two excited states (n=1 and n=2). hint: in evaluating integrals of this type, ∫[infinity]−[infinity]f(x)dx=0 if f(x) is an odd function of x, and ∫[infinity]−[infinity]f(x)dx=2∫[inf inity]0f(x)dx if f(x) is an even function of x. match the items in the left column to the appropriate blanks in the equations on the right. make certain each equation is complete before submitting your answer.
