Answer:
Explained
Explanation:
Big Bang happened about 13.7 billion years ago. It is most accepted theory of universe creation. Several experiments have confirmed the happening of big bang back then, in promising way. One of this experiment is the red shift experiment. A scientist named Edwin Hubble tried to study the spectrum of stars. He made a shocking revelation that universe is rushing outwards in all directions. Light travelling away registers on the red side. He observed that the distance stars showed red shift in accelerated manner. If the universe is accelerating that means, at one point it would have been smaller, in fact it was as small as an atom, some how it exploded and lead to formation of the expanding universe.

<span>The question is asking us what is BEST to say about a runner who is running at a constant velocity? A constant velocity (=speed) means that they are not getting faster or slower - they are running exactly as fast all the time. This meanst that their speed does not change, so their change of speed is equal to 0. A change of speed is called acceleration so their C. Their acceleration is zero. - C is the correct answer. </span>
