Question

how will an object at rest be affected if multiple forces working on it are opposed but unbalanced? (1 point)

motion will be either created, stopped or changed.

the acceleration of the object will increase.

the unbalanced forces will cause the object to produce a humming sound.

the mass of the object will decrease.

Explanation:

According to Newton's first law of motion, an object at rest stays at rest unless acted upon by an unbalanced force. Unbalanced forces can create motion (if the object was at rest), stop motion (if the object was moving and the unbalanced force is in the opposite direction to decelerate it to rest), or change motion (alter the speed or direction of a moving object).

• The acceleration of an object depends on the net force and mass (\(F = ma\)). Just knowing there are unbalanced forces doesn't directly imply acceleration will increase as the mass and magnitude of net force change relationship isn't clear from the question's context.
• Unbalanced forces don't cause a humming sound. Sound is usually related to vibrations in a medium in a specific frequency range due to other mechanisms (like forced vibrations in a particular setup, not just general unbalanced forces on an object).
• Mass is an intrinsic property of an object and is not affected by forces acting on the object (in non - relativistic cases, which is the context here as it's a basic physics force - motion question).

Answer:

Motion will be either created, stopped or changed.
