The intensity of sunlight at the distance of the Earth's orbit is 1380 W/m2. An Earth-orbiting satellite has a solar panel that measures 1.35 m by 4.86 m, which converts solar energy to electrical energy with an efficiency of 26%. In one hour, how much electrical energy does the panel produce? Assume that the satellite's attitude control jets keep the panel oriented perpendicular to the incoming sunlight.
assume a bar 2 m long expands 0.6 cm when heated. By how much will a bar 100 m long of the same material expand when similarly heated.
