Explanation :
Edwin Hubble used a telescope to discover the movement of galaxies in 1929. He was an American Astronomer.
The telescope invented by him is called a Hubble telescope. It has a 2.4-meter mirror.
He gives the relation between the distance to a galaxy and its recessional velocity. This is known as the Hubble law. The relation is as follows :

where,
is recessional velocity.
is Hubble constant.
is distance.
<em>So, the given statement is True.</em>
They're never the same ray.
Answer:
44.1 m
Explanation:
Consider the displacement being x:
x = (g•t²)/2
x = (9.8•3²)/2
x = (9.8•9)/2
x = 88.2/2
x = 44.1 m
Explanation:
My sources says "Inertia is an intrinsic characteristic of the object related to its mass. Inertia tells you how much force it will take to cause a particular acceleration on the object. Momentum is a function of an object's mass and velocity. Momentum is a measure of the kinetic energy of the object."
