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.)

2.4 x 10^8 Joules

Explanation:

1. 10m x 10 m =100 m^2

Or (10 x 100 )cm x (10 x 100)cm = 1,000,000cm^2

2. Converting to an hour: 1 hour= 60 minutes

3. 4.0 J x 1,000,000 x 60 minutes ^ -1 = 2.4 x 10^8 J
