e A grandfather clock is powered by thedescent of a 4.35-kg weight. (a) If the weight descends through adistance of 0.760 m in 3.25 days, how much power does it deliverto the clock? (b) To increase the power delivered to the clock,should the time it takes for the mass to descend be increased ordecreased? Explain

A large cruise ship of mass 6.20 x 10' kg has a speed of 11.6 m/s at some instant. (a) What is the ship's kinetic energy at this time? Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. J (b) How much work is required to stop it? (Give the work done on the ship. Include the sign of the value in your answer.) Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error.

A hydroelectric power facility converts the gravitational potential energy of water behind a dam to electric energy. (For each answer, enter a number.) (a) What is the gravitational potential energy (in J) relative to the generators of a lake of volume 38.0 km3 (mass = 3.80 ✕ 1013 kg), given that the lake has an average height of 42.0 m above the generators? ?J   (b) Compare this with the energy stored in a 9-megaton fusion bomb. Elake/Ebomb =

Give a specific example of a system with the energy transformation shown. In the question, W is the work done on the system, and K, U, and Eth are the kinetic, potential, and thermal energies of the system, respectively. Any energy not mentioned in the transformation is assumed to remain constant; if work is not mentioned, it is assumed to be zero. U → ΔEth
