At what rate, in watts, is the Earth losing rotational kinetic energy due to tidal braking? [Hint:The rotational kinetic energy of the earth, Erot-0.51w², where w=2T/P is the rotational angular speed,Pbeing the Earth's rotationalperiod. The moment of inertia of the Earth, I=(2/5)MR².] At what rate, in watts, is the Earth losing rotational kinetic energy due to tidal braking?
