Question

even though forces are acting on this box, it remains at rest on the table. which force is represented by vector a? static friction air resistance kinetic friction tension

Explanation:

The box is at rest, so the horizontal forces must be balanced. Vector \( F_d \) is a horizontal applied force, so vector A must be a force opposing it to keep the box stationary. Static friction acts on objects at rest to oppose impending motion, air resistance is for moving objects in air, kinetic friction is for moving objects, and tension is a pulling force (not applicable here). So vector A is static friction.

Answer:

static friction
