Answer:

as a result, the angle theta equals to zero degree because there is no difference and angle between the direction of applied force and the direction of displacement. the work done by a force can then be positive or negative. best sign tells us about the direction of energy transfer.

Answer:

Positive

Explanation:

W=f*s*cos theeta

Cos function decreases from 0° to 90° at the same time it'll b in 1st quadrant (in which all trigonometric ratios are positive) if the angle becomes more than 90 cosine will b negative as cos in 2nd quadrant is negative
