MODS close this thread down i figured out the answer myselfHomework Statement
A refrigerator has a coefficient of performance of 2.16. Each cycle it absorbs an amount of heat equal to 3.435×104 J from the cold reservoir.
i need to find a) the mechanical energy required each cycle to operate...
ummm you can forget about it now. I already turned it in with that answer on it. No problems. Thanks for helping though. I might hang around here sometimes so be on the lookout for more questions. Take care all.
I know about Potential Energy and Kinetic Energy but I don't know how the both of them go together
For question number 6, i think the kinetic energy has turned into heat due to friction of the floor on the ball?
For question number 3, at the ground level, the crate has all Kinetic Energy...
A few questions i don't understand on the huge holiday assignment for the three day weekend.
1) Why are most mountain roads designed so that they weave back and forth with a gradual slope rather than going straight uphill.
2) What are the work-energy transformations involved in throwing a...
