FibreOpticLights for Ceiling

An 80kgastronaut has gone outside his space capsule to do some repair work. Unfortunately, he forgot to lock his safety tether in place, and he has drifted 5.0maway from the capsule. Fortunately, he has a 1000Wportable laser with fresh batteries that will operate it for 1.0h. His only chance is to accelerate himself toward the space capsule by firing the laser in the opposite direction. He has a role="math" localid="1649937737036" 10-h supply of oxygen. How long will it take him to reach safety?

The magnetic field is uniform over each face of the box shown in FIGUREEX31.6. What are the magnetic field strength and direction on the front surface?

Only 25%of the intensity of a polarized light wave passes through a polarizing filter. What is the angle between the electric field and the axis of the filter?

A rocket cruises past a laboratory at 1.00x106m/sin the positive x-direction just as a proton is launched with velocity (in the laboratory frame) v=1.41x106i^+1.41x106j^m/s. What are the proton’s speed and its angle from the y-axis in (a) the laboratory frame and (b) the rocket frame?

Horizontal polarizing occurs when light reflects off horizontal surfaces like the road, water, or snow. A vertically oriented polarized filter will reduce glare while still allowing many light to experience. A polarized filter on your camera can assist decrease glare. The identical principle applies to polarized sunglasses.
