An object accelerates 20.8 m/s2 when a force of 8.9 newtons is applied. What is the mass of the object? *

In a system, when potential energy decreases, then entropy also decreases. true false

We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?

Since the energy was not raising the temperature of the water during these segments, what was the energy used to do instead? your answer must include an explanation of what is happening to the molecules.
