The distance of galaxy from a person.
Given:
A galaxy is travelling away from us at 1.0% of the
Formula used:
Hubble’s law
Here, v is speed of light , H0 is Hubble’s constant and d is distance
Calculation:
Speed of light is equal to
1% of speed of light is
Value of H0 is
Number of km in Mpc is
For converting Hubble’s constant in the unit of per second , we divide the value of Hubble’s constant (km/sec/Mpc )by
So Hubble’s constant in sec-1 is
