Physics 110: Assignment 9

Due MONDAY, December 9.

  1. Suppose we continually add mass to a neutron star. What happens to its radius, and then to the radius of the event horizon of the black hole, as it grows from 2 to 4 solar masses?

  2. The light which comes from the center of a spiral galaxy tends to be yellow to red, while light from the spiral arms is bluer. What does this tell you about the stars which make up those parts of the galaxy? What does it tell you about the history of the galaxy?
