Question

Sometime in the afternoon, the shadow of a 3m high stick, standing vertically, is 3.5 m long on the ground. If the same stick is placed, also standing vertically and at the same time in the afternoon, in a flat-bottomed pool filled with 2 m of water, how long is the shadow on the bottom of the tank? 10 points The average (rms) intensity of solar radiation is 1350(W)/(m^(2)) at the surface of the Earth. The mean Earth-Sun distance is r_(E)=150 million km . (a) Calculate the average (rms) intensity of solar radiation on the surface of Jupiter. The mean Jupiter-Sun distance is r=780 million km. (b) Calculate B_(0) and B_(rms) on the surface of Jupiter. (c) What is the power radiated by the Sun? 10 points There is a light source on the bottom of a pool. The bright spot above the light source on the surface of the water is a circle with a diameter of 4 m . What is the depth of the pool? (For water n=1.33 ). 10 point Plz help !
