Mike D asked:


Neglecting energy absorbed or reflected by Earth’s atmosphere, the solar energy hitting 1 square meter of Earth’s surface is 1360 J/s (the solar constant). How long does it take a baseball diamond (90 ft on a side) to receive 1 megaton of solar energy? (Hint: A 1 megaton bomb produces about 4 1015 J.)
