Question

Which of the following lists the correctrequirements for a black hole to form? 

A. The star must be 29 times larger than Earth's sun, and a supernova explosion must have occurred.  B. The star must be 10 to 28 times larger than Earth's sun, and a supernova explosion must not have occurred.  C. The star must be 10 to 28 times larger than Earth's sun, and a supernova explosion must have occurred.  D. The star must be 29 times larger than Earth's sun, and a supernova explosion must not have occurred.​

Answer 1

A. The star must be 29 times larger than Earth's sun, and a supernova explosion must have occurred.

Step-by-step explanation:

The object has a strong gravitational force. Usually, a black hole has an enormous gas with an overall structure that is present in space. When determining the physical appearance, then it is about 28 times bulky and massive when comparing it with the sun. Therefore energy is pulled by the black hole from the surrounding galaxies.

The black holes are amazing because they have invisible beats that pass through the scatter forming a cosmic object that continues to captivate the explosions.

Answer 2

A

Step-by-step explanation:

Formation of black holes occur during the death of massive stars (at least 25 times larger than Earth’s sun). When the fuel of the massive star is exhausted, the star’s nuclear forces are unable to counter the gravitational collapse due to its own weight. The star dies in a supernovae and the remnant is a black hole.
