Which of the following objects is in equilibrium : an object that moves at constant acceleration, an object that moves at constant velocity

An object that moves at constant velocity

Explanation:

For an object to be in equilibrium, according to Newton's first law, the object must maintain its state of rest or movement without a resulting force acting on the object.

In this case the object in both options is in motion, but the only one in which that movement is constant and without resulting forces is when it moves at constant speed, so it is in equilibrium.

On the other hand, when it moves with at constant acceleration, by Newton's second law ( is the mass and is acceleration), if there is an acceleration there will be a resultant force so the object is not in equilibrium.

The answer is an object that moves at constant velocity is in equilibrium.

- measure reactants precisely. ( first choice)

- stir to the reaction take place. ( second choice)

- wait patiently until the reaction completes. ( fourth choice)

- make sure to recover as much copper as possible. ( last choice)
