At the surface of the Earth, the Sun delivers an estimated 1.00 kW/m- of energy. Suppose sunlight hits a 17.1 m by 36.1 m roof at an angle of 90.0. a) Estimate the total power incident on the roof. Submit Answer Tries 0/100 b) Find the radiation pressure on the roof. (Assume the roof is black and totally absorbs the sunlight!) Submit Answer Tries 0/100 Post Discussion Send FeedbackIn order to visually examine sunspots through a telescope we have to reduce the intensity of the sunlight to avoid harming our retina. To accomplish this intensity reduction astronomers have mounted two linear polarizers on their telescope. The second polarizer has its plane of polarization at an angle of 92.2" relative to the horizontal. If they want a reduction of the intensity of the sunlight by a factor 0.8697, what angle does the polarization plane of the first polarizer have to form with the horizontal? Give the angle in degrees and assume that 0,
