Aflat and infinitely large sheet with uniform charge density o moves with constant speed v in a direction parallel to its surface. confirm the differential form of poynting's theorem at every point not on the sheet.

What was the first instrument to ever record an earthquake?

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
