<h3><u>Answer;</u></h3>
is a relationship between distance and velocity
<h3><u>Explanation;</u></h3>
- According to Hubble's Law the recessional speed of a galaxy is directly proportional to its distance.
- <em><u>The Hubble Constant is the unit of measurement used to describe the expansion of the universe, it is the relationship of the recessional speed of a galaxy and its distance.</u></em>
- The formula showing the relationship is given by the formula:
v = Hd, where: v = velocity of a galaxy, in km/s. H = Hubble Constant, measured in km/s/Mpc and d is the distance in km.
