Answer and Step-by-step explanation:
<u>C and D is the answer.</u>
It needs a lot of mass so that it can collapse on itself to form a black hole, and when it dies, it also collapses on itself, forming a black hole.
A is incorrect because the mass of our sun hasn't made it to collapse, and it still has some billions of years before the mass increases.
B is incorrect because the hydrogen needs to be depleted in order for the sun/star to start the nuclear process.

Use a calculator you should get 36.156
change in velocity = 20 - 0 = 20
change in time = 2 seconds
Divide the change in velocity over the change in time: 20/2 = 10
The average acceleration is 10 m/s^2
I.e, each second, the speed increases by 10 m/s
Check the picture below.
now, bear in mind that, there are 60minutes in 1 degree, so 23' is just 23/60 degrees or about 0.38 degrees.
and 29' is just 29/60 degrees or about 0.48 degrees.
so 16°23' is about 16.38°, and 49°29' is about 49.48°

make sure your calculator is in Degree mode.
The answer to this question is option D
