HOW LONG DOES IT TAKE A BASEBALL DIAMOND (90 FT ON A SIDE) TO RECEIVE 1 MEGATON OF SOLAR ENERGY?
Nov 29th
Question by sweetnovember4:
How long does it take a baseball diamond (90 ft on a side) to receive 1 megaton of solar energy?
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 x10^15 J.)

TURNING LIGHTS ON AND OFF USES ENERGY, BUT HOW LONG SHOULD THEY BE OFF IN ORDER TO SAVE ENERGY?
Aug 31st
Question by Corey W:
Turning lights on and off uses energy, but how long should they be off in order to save energy?
When I was younger, my mom always yelled at me for turning the lights on and off rapidly, but i suppose i never understood why, and to this day still. If I use a light for 5 mins and turn it off leave for 10 mins and come back to turn it on for 5 more, am i using more energy than keeping it on for 20 mins straight? Thanks!
hopefully information on Incandescent, CFL, and Fluorescent lights could be explained to me! thanks!
