<h2><u>ANSWER</u></h2>
The simplest definition of a black hole is an object that is so dense that not even light can escape its surface. If we squished the Earth's mass into a sphere with a radius of 9 mm, the escape velocity would be the speed of light. Just a wee-bit smaller, and the escape velocity is greater than the speed of light.

Answer: gravitational force between them will be reduced by one - fourth ( 1/4) of its initial value.
Explanation: Gravitational force between two bodies obeys inverse square law. That is, gravitational force between two bodies is inversely proportional to the square of the distance between the two bodies.
When the mammoth is at a distance that is twice the original distance, the gravitational force between them will be reduced by one - fourth ( 1/4 ) of its initial value.
83 km/h * 2.5 hours (3:30 - 1:00) = 207.5 km
207.5 km - 15 km = 192.5 km

Explanation:
m1(v1) + m2(v2)
Opposite turns the plus to subtraction.
80(8) - 120(4.0)
60 - 480 = 160 kg m/s to the right
