1. Which description best summarizes the steps that take place during black hole formation, in the correct order?

Supernova explodes a massive star; remaining core expands; nuclear reactions diminish the effects of gravity.

Supernova triggers fusion reactions; massive star implodes due to extreme radiation; volume and mass of star increase rapidly.

A massive star depletes its nuclear fuel; gravity overpowers the star; supernova occurs; core of star collapses.

A small star gains mass through fusion reactions; core of star collapses; increased radiation triggers a supernova.


2. Astronomers think that most galaxies are centered by a (nebula, large planet, black hole, massive star), which exerts (centripetal force, magnetic pull, gravitational pull, centrifugal force) that binds the galaxy together.


3. Where would scientists look to observe a black hole?

The center of the Milky Way

The center of the sun

The solar system asteroid belt

The edge of the solar system

Respuesta :

Answer:

1. A massive star depletes its nuclear fuel; gravity overpowers the star; supernova occurs; core of star collapses

2. black hole; gravitational pull

3. The center of the Milky Way

Explanation:

The description that summarizes the steps that take place during black hole formation, in the correct order is C. A massive star depletes its nuclear fuel; gravity overpowers the star; supernova occurs; the core of the star collapses.

Astronomers think that most galaxies are centered by a black hole which exerts a gravitational pull that binds the galaxy together.

In order for scientists to observe a black hole, they should look at the center of the Milky Way.

Black hole simply means the region of spacetime where there's a strong gravity such that there's no electromagnetic radiation or particles that can escape.

It was believed that black holes were formed after the Big Bang when there was a collapse of the center of a massive star. The formation is that a massive star depletes its nuclear fuel; gravity overpowers the star; supernova occurs; the core of the star collapses

In order for scientists to observe a black hole, they should look at the center of the Milky Way which is the hit collection of gas, stars and dust.
