A cоmmunicаtiоns sаtellite оrbiting the eаrth has solar panels that completely absorb all sunlight incident upon them. The solar panels are m long and m wide. The average intensity of the sun’s radiation incident upon the earth is 1.4 kW/m. Suppose this is the value for the average intensity of sunlight incident upon the satellite’s solar panels, and that these panels are facing the sun. What is the total solar power absorbed by the panels?
