Some of the energy the car gained as it was pulled was lost because of heat from friction. The rest of the energy was transformed into potential energy. How much potential energy does the roller coaster car have at the top of the first hill? Use PE = m × g × h, and assume that g = 9.8 m/sec2.

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
