Answer:
T²= 4π²R³/GM
Explanation:
First we know that
Fg= Fc
Because centripetal force must equal gravitational force
So
GMm/R² = Mv²/R
But velocity is 2πR/T
So by substitution we have
GMm/R²= M (2πR/T)/T
We have
T²= 4π²R³/GM as period
The gravitational pull is weaker.

Answer:
Let's simplify step-by-step.
3 + 7b + 2 + 2b
Combine Like Terms:
= 3 + 7b + 2 + 2b
= ( 7b + 2b ) + ( 3 + 2 )
= 9b + 5
Answer:
= 9b + 5

It says an object will remain at rest unless external forces act upon it.
The sun is at the solstices on roughly June 21 and December 21.
June 21 is the "Summer" solstice in the Northern hemisphere.
At that time, the sun is directly overhead at a point on the Tropic
of Cancer, about 23.5° North of the equator.
December 21 is the "Summer" solstice in the Southern hemisphere.
At that time, the sun is directly overhead at a point on the Tropic
of Capricorn, about 23.5° South of the equator.
