What If? The coil and applied magnetic field remain the same, but the circuit providing the current in the coil is now changed. The new circuit has an emf of e m f = 20.0 V, and this allows a mass of 51.0 g added to the right side to balance the system. What is the value of the resistance R (in Ω)?

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
