Alasik vision-correction system uses a laser that emits 10-ns-long pulses of light, each with 3.0 mj of energy. the laser beam is focused to a 0.80-mm-diameter circle on the corneawhat is the electric field amplitude of the light wave at the cornea? .

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?
