Hi, so I have been asked to find an expression that governs the rate of solar energy incident upon the Earth, if the Earth lies at a distance, D from the Sun of 1.5x10^11 m, and the Earth has a radius, RE. I also know the Sun has a power output of about 4x10^26 watts.
At this point I have considered looking at P = W/T, I think the main issue is I have no clue what the rate of solar energy incident upon the Earth is supposed to look like written out in equation form. I know the question is asking the rate at which the Earth absorbs energy from the sun, but I'm not sure what to do or where to go from here. Please help me! Thank you!
