B) Here are four different distance-time (d-t) graphs. In one of them, the cart does not move. In
the other three, the more time that elapses, the further the cart has gone. One graph shows that
the cart travels at a constant speed. In another, the cart travels faster at the beginning. In
another one, the cart travels fastest at the end. Identify which graph corresponds to which
motion. (Hint: Compare the distance traveled in the first few seconds of the trip with the distance
traveled in the last few seconds of the trip.)

An electron is trapped at a defect in a crystal. the defect may be modeled as a one-dimensional, rigid-walled box of width 1.00 nm. (a) sketch the wavefunctions and probability densities for the n 1 and n 2 states. (b) for the n 1 state, nd the probability of nding the electron between x1 0.15 nm and x2 0.35 nm, where x 0 is the left side of the box. (c) repeat (b) for the n 2 state. (d) calculate the energies in electron volts of the n 1 and n 2 states
