On a sunny day, solar energy reaches earth at a rate of 4.0 . suppose a house has a square, flat roof of dimensions 10. m by 10. m. calculate how much solar energy reaches this roof in 1.0 h. (note: this is why roofs painted with light-reflecting paint keep buildings cooler than black, unpainted roofs. the painted roofs reflect most of this energy rather than absorb it.)
