This is how you can fulfill your goals. in this article, some question and answer examples that you could certainly utilize to improve your knowledge and gain insight that will guide you to preserve your school studies.

## Question:

Find an expression for the square of the orbital period.

## Answer:

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

They could hopefully help the student answer the question by implementing the questions and answer examples. You will be able to then have a discussion with your classmate and continue the school learning by studying the question alogside each other.
