- Answer in rev/sA pulsar is a rapidly rotating neutron star. The Crab nebula pulsar in the constellation Taurus has a period of 33.5×10−333.5×10-3 s, radius 10 km. And suppose its mass is 2.5×10302.5×1030 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. What is the angular momentum of the pulsar? Give your answer in the scientific notation, in the normalized form.L=L= ×10×10 J s Suppose the angular velocity decreases at a rate of 7.4×10−147.4×10-14 rad/s2. What is the magnitude of the torque on the pulsar? Give your answer in the scientific notation, in the normalized form.τnet=τnet= ×10×10 N mDisks A and B separately rotate without friction about a pole that goes through their centers. Both rotate in the same direction (see fig.). Disk A has a mass MA = 2.00 kg, radius RA = 0.600 m, and an initial angular speed wA 20.0 rad/s. Disk B has MB = 4.00 kg, RB = 1.00 m, and wB = 7.24 rad/s. The disks slide freely along the pole toward each other and they stick together, afterward rotating as a single combined unit. Given that the moment of inertia about the center of a disk is | = ½ MR2, the angular speed of the disks wAB after they are joined is A
