As a result of the friction of tides, the earth rotates more slowly as time progresses. Each year the time it takes for the earth to complete one rotation increases by 20microseconds. The mass of the earth is 5.9785*10^24 kg and the radius is 6.37*10^6 m. Assuming it has uniform density, what is the rotational kinetic energy (J) of the earth? At what rate (J/yr) is kinetic energy being lost due to friction? Assuming the eath temperature is 15 degrees C, at what rate [J/(yr*K)] is entropy being generated due to tidal friction?
