To solve a problem using the equation for kepler’s third law, enrico must convert the average distance of mars from the sun from meters into astronomical units. how should he make the conversion? multiply the average distance by 1.5 × 1011 multiply 1.5 × 1011 by the average distance divide the average distance by 1.5 × 1011 divide 1.5 × 1011 by the average distance

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
