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, equal 25 - N forces act on opposite sides of the marble, creating a balanced - force situation. In the second option, the marble stops due to an unbalanced force (the wall's resistance). In the third option, the upward and downward forces are not equal, so it's an unbalanced - force situation. In the fourth option, the marble starts moving without an obvious opposing force, indicating an unbalanced force.

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.
