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 and the results of the integrals
that give <x> and <x^{2}>. Vary n from 1 to 10.

Questions

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

b. For n = 1, what is Dx?

c. What do you think <x> and <x^{2}> should become in the classical
limit? Why?
