Question
Hubble′s law is related with
Options
A.planetry motion
B.speed of galaxy
C.black hole
D.comet
Solution
Hubble′s law states that speed of a star is b directly proportional to distance from the star i.e.
v ∝ r ⇒ v = Hr
where H is Hubble′s constant.
v ∝ r ⇒ v = Hr
where H is Hubble′s constant.
