Based on the situation above the the work done was 400 Joules. <span>Q = FS cos(theta) is the so-called work function. It's important to learn the work physics; you'll see it over and over in science/physics class. Theta is the angle between the force vector F and the distance vector S. In your problem we assume theta = 0, the two vectors were assumed aligned.</span>
Albedo is how much sunlight reflects off the surface of the Earth. More albedo could mean a number of things. Higher temps, more photochemical smog, it all depends on where the albedo is occurring.
