Please answer the following 3 questions
regarding the Physlet:

Description

A particle is in a one-dimensional box of length a=1. The
states shown are normalized. Shown are Psi^{*} p Psi^{ }and
Psi^{*} p^{2} Psi and the results of the integrals that give <p>
and <p^{2}>. The results are given in terms of hbar and ( hbar)^{2},
respectively. Vary n from 1 to 10.

Questions

a. What do you notice about the values of <p> and <p^{2}> as you vary
n?

b. For n = 1, what is Dp?

c. If the mass of the particle is m, what is the <E_{n}> as a
function of n?
