Final answer:
When more force is applied through gear A, the angular velocity of gear B decreases in magnitude.
Step-by-step explanation:
Angular velocity is the rate at which an object rotates around a fixed axis. When more force is applied through gear A, it creates a larger torque. Torque is the rotational equivalent of force and is responsible for changes in angular velocity. In this case, since gear B turns counterclockwise, the increase in torque from gear A will cause gear B to rotate more slowly, resulting in a decrease in angular velocity.
