Work is a ; a + or - sign on a work value indicates information about . vector; b. whether the work adds or removes energy from the object vector, c. the direction of the work vector scalar; d. the direction of the work vector scalar; e. whether the work adds or removes energy from the object

Work is a scalar; a + or - sign on a work value indicates information about the direction of the work vector scalar

Option D

Explanation:

The measure of work done (W) on an objects by a given force can be determined to utilize the equation,

Where, F represents the force and d is the separation over which the force demonstrations and theta is the point among F and d. Recognize that the angle remembered for the condition isn't only any old angles; it has a particular definition that must be recalled when taking care of such problematic.  Work is a scalar quantity not a vector quantity. It does not depend on the direction as a vector depends.

c) power lifting, will be your answer.
