Final answer:
Bolts with left-handed threads are loosened by turning them counterclockwise. When more torque is applied to a gear meshing with another gear, the angular velocity of the second gear increases in magnitude.
Step-by-step explanation:
The question you've asked relates to the behavior of bolts with left-handed threads. Typically, standard bolts have right-handed threads and are tightened by turning them clockwise. Conversely, bolts that have left-handed threads are loosened by turning them counterclockwise. This is the opposite of what you might be used to with standard right-handed threads. Therefore, the answer is B) Loosened.
In the context of gears, when a force is applied to gear A causing it to turn clockwise and it meshes with gear B which turns counterclockwise, if more force is applied to gear A, the angular velocity, or speed at which gear B rotates, would increase in magnitude. This increase occurs due to the additional torque transmitted from gear A to gear B.
