Two planets X and Y travel counterclockwise in circular orbits about a star as shown in Figure P11.14. The radii of their orbits are in the ratio 3:1. At one moment, they are aligned as shown in Figure P11.14a, making a straight line with the star. During the next five years, the angular displacement of planet X is 90.0 as shown in Figure P11.14b. What is the angular displacement of planet Y at this moment?
A star rotates in a circular orbit about the center of its galaxy. The radius of the orbit is 2.9 x 10^20 m, and the angular speed of the star is 9.7 x 10^-15 rad/s. How long (in years) does it take for the star to make one revolution around the center? Note: the tolerance is in the 2nd significanct digit and indicate the unit
A pulsar may form when a star of medium mass dies. On July 4, 1054 CE, Chinese astronomers witnessed the death of a star that led to the formation of the pulsar in the Crab Nebula. Contemporary astronomers have measured the angular speed of the nebula's pulsar as ? = 1.89 ✕ 102 rad/s and have found that the pulsar is slowing down such that ? = 2.39 ✕ 10−9 rad/s2. (a) Determine the period of the pulsar's rotation. s(b) Determine the number of seconds by which this period increases each second (dT/dt).

A star rotates in a circular orbit about the center of its galaxy. The radius of the orbit is 1.3 x 1020 m, and the angular speed of the star is 5.6 x 10-15 rad/s. How long (in years) does it take for the star to make one revolution around the center?
I am working on this problem and have been getting wrong answers I am not sure if it is due to integration or not but what I have so far determined is that. Note y1 = y1(x) and y2 = y2(x) distance to dm (r)=x Differential Area (dA) = (y1 - y2) * dx Differential Mass (dm) = sigma * (y1-y2) * dx Differential Moment (dI) = x^2 * sigma(y1-y2)dx
