Hey, I spent the entire morning completing my review, and have these last six problems that I need to know how to solve before my final, so I am looking for some quick help on how to complete these.

Also for 2: I got 3726 watts x 3600 seconds, which makes E/hour = 13,420,800 or 13.42MJ or 0.01342 Joules. Then do I just use, 0.01342 = (.5)(1.12)(V2). This gives me Sqroot( [(2)(.01342)]/1.12) ) = V = 0.15480 Volts?
