Question

Mass 10 kg and 10 grams role towards each other with a speed v m per second hand 1 m per second on a smooth slow after collision with what speed be moves

Answer 1

Smaller black holes can form from the gravitational collapse of a gigantic star, which forms a singularity from which nothing can escape — not even light, hence the name of the object. No one is quite sure what lies within a black hole, or what would happen to a person or object who fell into it – but research is ongoing.

An example is gravitational waves, or ripples in space-time that come from interactions between black holes. This was first predicted by Albert Einstein at the turn of the last century, when he showed that time and space are linked; time speeds up or slows down when space is distorted.
