Answer:
I'm not great at science, but I believe that the answer is elastic potential energy.
Explanation:
Components of mechanical systems store elastic potential energy if they are deformed when forces are applied to the system. Energy is transferred to an object by work when an external force displaces or deforms the object.
Answer:
82780.42123 m/s
14.45 days
Explanation:
m = Mass of the planet
M = Mass of the star = 
r = Radius of orbit of planet = 
v = Orbital speed
The kinetic and potential energy balance is given by

The orbital speed of the star is 82780.42123 m/s
The orbital period is given by
The orbital period is 14.45 days
<span>A chemical change occurs when the bonds between atoms and molecules change, and a new substance forms. This chemical change may or may not be permanent and may or may not physically affect an object. However, it always affects the chemical composition.</span>
