Explanation:
The law of conservation of energy is one of the fundamental laws of science that helps to understand energy in nature.
Energy is the ability to do work. There are different forms of energy.
Generally, energy is classified into potential and kinetic forms of energy. Potential energy is the energy at rest in a body. It is due to the position of the body.
Kinetic energy is the energy due to the motion of a body.
There are different forms of kinetic and potential energy and they are related by the law of conservation of energy.
The law states that "in an isolated system, energy is neither created nor destroyed by transformed from one form to another".
An isolated system is a system in which there is no exchange of matter and energy.
Due to this we know that no new energy is created or destroyed, they are only transformed from one form to the other.

Answer is A
to determine an objects true motion, you need velocity, which requires direction, time and distance!
Answer:
Mass of the planet = 6.0 × 
Explanation:
Time period = 2π (R + h) / v
Orbital speed (v) = √GM / (R + h)
T² = 4π² (R + h)² / (GM/ (R + h))
= 4π² (R + h)³ / GM
making m the subject of the formula
m = 4π² (R + h)³ / GT²
= 4π² ( 6.38 × 
+ 230 × 10³ )³ / ( 6.67 × 
) × (89 × 60)²
= 4π² ( 6610000)³ / ( 6.67 × ) × (89 × 60)²
= 5.99 ×
= 6.0 ×
