Final answer:
When more force is applied to gear A resulting in increased torque, the angular velocity of gear B increases in magnitude if no other physical changes occur.
Step-by-step explanation:
When gear A, which turns clockwise, meshes with gear B turns counterclockwise, and more force is applied to gear A, the torque on gear B is increased. Torque is the rotational equivalent of a linear force and affects the angular acceleration of an object. Therefore, as the torque applied through gear A increases, it causes an increase in the angular acceleration, and consequently, an increase in the angular velocity of gear B, assuming no other physical changes (such as increased resistance) occur. This is reflected in an increase in the magnitude of gear B's angular velocity.
