The orbiting space shuttle moves around earth well above 99% of the atmosphere, yet it still accumulates an electric charge on its skin due, in part, to the loss of electrons by the photoelectric effect with sunlight. suppose the skin of the shuttle is coated with ni, which has a relatively large work function f=4.87 ev at the temperatures encountered in orbit. (a) what is the maximum wavelength in the solar spectrum that can result in the emission of photoelectrons from the shuttle’s skin? (b) what is the maximum fraction of the total power falling on the shuttle that could potentially produce photoelectrons?

Acoil formed by wrapping 80 turns of wire in the shape of a square is positioned in a magnetic field so that the normal to the plane of the coil makes an angle of 28.0° with the direction of the field. when the magnetic field is increased uniformly from 200 µt to 600 µt in 0.400 as, an emf of magnitude 80.0 mv is induced in the coil. what is the total length of the wire?
