The grounded conductor of a branch circuit is permitted to serve as the equipment grounding conductor for a replacement range or cooktop when all the following conditions are met, except for

a. the grounded conductor is not smaller than no. 10 copper or no. 8 aluminum
b. the individual branch circuit is existing
c. the grounded conductor is insulated, unless it is part of type se cable
d. the branch circuit uses listed wire connectors

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
