Question

which statement accurately describes a balanced force? a 25 - n force acts on the left side of the marble at the same time as a 25 - n force acts on the right side of the marble. a marble rolling downhill suddenly comes to rest at a garden wall. a 2 - n force presses down on the marble at the same time as a 1.5 - n force presses up on the marble. a marble resting on the sidewalk suddenly begins to roll downhill without being touched.

Explanation:

A balanced force occurs when two forces acting on an object are equal in magnitude and opposite in direction, resulting in no net - force and no change in the object's motion. In the first option, a 25 - N force on the left and a 25 - N force on the right of the marble meet these criteria. The second option shows a change in motion due to an unbalanced force (the wall's resistance). The third option has unequal forces (2 N and 1.5 N), so it's unbalanced. The fourth option implies an external unbalanced force causing the marble to move from rest.

Answer:

A. A 25-N force acts on the left side of the marble at the same time as a 25-N force acts on the right side of the marble.
