Answer this one right: ( jim and david decide to arm wrestle to determine who is stronger. jim uses all of his strength, but david wins and is able to push jim's hand to the table. the forces acting on jim's hand during the match a. are unaffected by david. b. have a net force of zero. c. are balanced. d. are unbalanced.

unbalanced.

Explanation:

Unbalanced force may be defined as the force that can change the motion of an object. This force is not equal and opposite. The object moves in the direction of force applied at greater magnitude.

Jim and David do arm wrestle and David wins because the force applied by David is more than the force applied by Jim. David is able to push Jim's hand as the magnitude of force is more in case of David. Hence, the force acting on Jim's hand is unbalanced force.

Thus, the correct answer is option (D).

it's a.true. i'm kind of smart.
