Answer:
The mass of the star is, M = 5.9567x10³⁰ Kg
Explanation:
Given
The orbital period of the planet, T = 0.76 year
= 2.3967x10⁷ seconds
The distance between planet and sun, R+h = 1.2 a.u
= 1.795 x 10¹¹ meters
The orbital period of the planet is given by the formula

Squaring and solving for M

Substituting the given values in the above equation
M = 5.9567 x 10³⁰ Kg
Hence, the mass of the star the planet is orbiting, M = 5.9567 x 10³⁰ Kg

Explanation:
as toddler will go away then come closer
P.E = mgh
This is the formula for potential energy.
This is where m is mass, g is the acceleration due to gravity, and h is height.
All you have to do is multiply all these numbers together.

Explanation:
Explanation:
A metal such as copper is a <u>conductor</u> because it provides a pathway for electric charges to move easily. A material such as rubber is an <u>insulator</u> because it <u>resists</u> the flow of electric charges. A material that partially conducts electric current is a <u>semiconductor</u>. These materials include <u>group 3 and group 5</u> elements.
