5. A 4 kg ball that is moving straight upward has 17 J or kinelic energy and ils lolal mechanical energy is 25 J. a) Find the gravilalional polenlial energy of the ball.

Determine the maximum r-value of the polar equation r =3+3 cos 0

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.

Arigid tank is divided into two equal parts by a partition. one part of the tank contains 3 kg of compressed liquid water at 400 kpa and 60°c while the other part is evacuated. the partition is now removed, and the water expands to fill the entire tank. determine the entropy change of water during this process, if the final pressure in the tank is 40 kpa. use steam tables.
