Answer
# Brief Explanations:
Hubble's constant is used to quantify the rate of universal expansion. It relates the recessional velocity of a galaxy to its distance from Earth. Friedmann's equations are related to the evolution of the universe but not specifically the rate - of - expansion constant. Lemaître made important contributions to cosmology but not the constant for the rate of universal expansion. Maxwell's work was mainly in electromagnetism.
