What is the formula for Hubble's law?.
- A.v = H0 × d
- B.d = H0 × v
- C.H0 = v / d
- D.v = d / H0
Model answer
What a good answer should say
- v = H0 × d
Explanation
Why this works
Hubble's law states that the velocity (v) of a galaxy is directly proportional to its distance (d) from us, with H0 being the Hubble constant. This relationship helps us understand the expansion of the Universe.
