Homework Help: Physics (please help!!)

Posted by Abigail on Friday, April 15, 2011 at 3:57pm.

The Crab pulsar (m=2.00x10^30 kg) is a neutron star located in the Crab Nebula. The rotation rate of the Crab pulsar is currently about 30.0 rotations per second, or 60.0pi rad/s. The rotation rate of the pulsar, however, is decreasing; each year, the rotation period increases by 1.00x10^-5 s. Justify the following statement: The loss in rotational energy of the pulsar to 1.00*10^5 times the power output of the Sun. ( The total power radiated by the Sun is about 4.00*10^26 W.)
