An electromagnetic plane wave at a certain location has an electric field pointed up which is given as a function of time as E = 54 V/m × sin (6x106 Hz × t). The magnetic field at the same location points south when the electric field points up. The wave is incident on a square piece of foil which is 3.6 m long on each side. Assume the foil is set up in the south-up plane. How much momentum is absorbed by the foil for the same time interval?
A space station, in the form of a wheel 133 m in diameter, rotates to provide an "artificial gravity" of 2.20 m/s2 for persons who walk around on the inner wall of the outer rim. Find the rate of the wheel's rotation in revolutions per minute that wi..
