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?

Answer the question in full details, thank you very much, Answer on the correct significant figures: A star of mass 1.87 x 10^31 kg and diameter 9.44 x 10^9 m rotates with a period of 26.0 days. Suddenly, the star changes size and rotates with a new period of 19.0 days. The mass of the star is conserved.

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.
