The speed of the galaxy relative to a person on Earth.
Given:
Galaxy is 12 billion light years away
Formula used:
Hubble’s Law
Here,
v is
H0 is Hubble’s constant
d is distanceCalculation:
Here d is equal to 12 billion light year=
1 light year =
So
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

- I do not understand the process to answer the second part of question b. Please help me understand how to get there!arrow_forwardRank the six combinations of electric charges on the basis of the electric force acting on 91. Define forces pointing to the right as positive and forces pointing to the left as negative. Rank in increasing order by placing the most negative on the left and the most positive on the right.
