Hint 1 Hint 2 A pulsar is a rapidly rotating neutron star. The Crab nebula pulsar in the constellation Taurus has a period of 33.5 10 3 s, radius 10 km. And suppose its mass is 2.2 1030 kg. The pulsar's rotational period will increase over time due to the release of electromagnetic radiation, which doesn't change its radius but reduces its rotational energy. a. What is the angular momentum of the pulsar? Give your answer in the scientific notation, in the normalized form. L = 10 Js b. Suppose the angular velocity decreases at a rate of 5.9 10-14 rad/s. What is the magnitude of the torque on the pulsar? Give your answer in the scientific notation, in the normalized form. Tnet = 10 Nm
