I’m not going to church tomorrow or Friday I don’t want to go go back up
The planets have (their) moons. So the answer would be planets.
The forces of gravity between two objects are smaller when the objects are farther apart.
Internal energy of the system changes by ΔE = 178 J.
Heat given to the system = Q = +658 J.
According to the first law of thermodynamics,
ΔE = Q + W
178 = 658 + W
∴ W = 178-658 = -480 J
Minus sign indicates that work is done by the system.
