PLEASE HELP THIS IS FOR A FINAL (NO LINKS PLEASE)

A solar array (containing 225 panels) at DIA converts light energy to electric potential energy with an efficiency of 28%. How much electric potential energy can be produced by the array each day of 33,000 J of energy reach each solar panel?

The star betelgeuse is about 600 light-years away. if it explodes tonight, a. we'll know because debris from the explosion will rain down on us from space.b. we'll know it immediately because it will be brighter than the full moon in the sky.c. we won't know about it until 600 years from now.d. none of the above.

If anyonee has done the momentum lab practical in physics can you give me the answers i am s lostt rnn : (
