SOLVED:The Crab pulsar (m ≈2 ·10^30  kg, R=12  km) is a neutron star located in the Crab Nebula. The rotation rate of the Crab pulsar is currently about 30 rotations per second, or 60 πrad / s. The rotation rate of the pulsar, however, is decreasing; each year, the rotation period increases by 10^-5  s . Justify the following statement: The loss in rotational energy of the pulsar is equivalent to 100,000 times the power output of the Sun. (The total power radiated by the Sun is about 4 ·10^26 W.

A pulsar is a rapidly rotating neutron star that emits a radio beam the way a lighthouse emits a light beam. We receive a radio pulse for each rotation of the star. The period T of rotation is found by measuring the time between pulses. The pulsar in the Crab nebula has a period of rotation of T=0.033  s that is increasing at the rate of 1.26 ×10^-5  s / y. (a) What is the pulsar's angular acceleration α? (b) If αis constant, how many years from now will the pulsar stop rotating? (c) The pulsar
