To calculate the center of gravity, divide total weight distance moment by total mass of the system. Thus, the center of gravity is 13 meter from left-hand side.
D. since the star would be larger than the sun, having more mass, its gravitational pull would be stronger thus pulling the planets into it. hope that helped!

Answer:
A.a space station orbiting Earth
Explanation:
As we know that kinetic energy given as
K.E.=1/2 m v²
Where m= mass
v= velocity
If the velocity of the object is zero then it posses zero kinetic energy.
We also know that when object at a height from the ground or from a reference line then it posses potential energy and it does not have kinetic energy because object is in rest position.
In the option B and C system is in rest position that is why these type of system posses zero kinetic energy.
So the answer is A.
A.a space station orbiting Earth
Answer:
C
Explanation:
The answer is c because Newton’s third law states “ for every action there is an equal and opposite reaction.” Since the car quit moving the book did not stay at rest because there was a reaction.
