It a stage known as the "Main Sequence" stage. Stars achieve nuclear stability at this point and remain in this stage until the end of their lives.

Answer:
Period for 1 revolution is 1.75 seconds
Explanation:
given data
revolutions R = 8
time t = 14 seconds
to find out
What is the period
solution
we know that Period is the time per revolution
so here period formula that is express as
period =
=
= 0.57 revolution in one second
so in 1 revolution =
seconds
so in 1 revolution = 1.75 seconds
so period for 1 revolution is 1.75 seconds
Answer:
vf=94.4 m/s
Explanation:
acceleration is the final velocity minus initial velocity divided by time
a = (vf-vi)/t
Given:
a= 14.2 m/s^2
vi= 0 (at rest)
t = 6.6
Solve for vf
a = (vf-vi)/t
a*t=vf-vi
(14.2)*(6.6)=vf - 0
vf=94.4 m/s
It’s red shift and blue shift because This only occurs when the frequency of the wave is made longer or shorter due to the movement of the source relative to the observer
