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
