Textbook Problem

The distance of a galaxy from our solar system is 10 Mpc. (a) What is the recessional velocity of the galaxy? (b) By what fraction is the starlight from this galaxy red shifted

(that is, what is its z value)?

To determine

(a)

The recessional velocity of the galaxy.

Explanation

Given:

Distance, d = 10Mpc

Formula used:

The recessional velocity is calculated by

  v=H0d

Calculation:

According to the Hubble's law the distance of the galaxy and the velocity of recession have direct proportional relation.

  v=H0d

Here, v is the velocity, H0 is the Hubble constant with the value 70km/s/Mpc and d is the distance of the galaxy.

The value of c in kilometer per second is 299792 km/s

To determine

(b)

The fraction of the starlight from the galaxy red shifted that is Z value.
