Consider a spiral galaxy that is moving directly away from Earth with a speed V=3.24*10^5 at its center. The galaxy is also rotating about its center such that points in the spiral arms are moving with a soeed V=5.750*10^5m/s relative to the center. If light with a frequency of 7.308*10^14Hz is emitted in both arms of the galaxy, what frequency is detected by astronomers observing the arm that is moving (a) toward and (b) away from Earth? Please break down steps.

According to Hubble's Law the velocity v of a galaxy moving away from Earth is proportional to its distance from Earth. Consider two galaxies one of which is twice as far away as the other from Earth at some instant of time (i.e. the ratio of their distances from Earth is 2 to 1). At subsequent times the ratio of their distances to Earth will be:
