Explanation:

Work is defined as the product of force and displacement in the direction of the force. When Nelle is carrying the box across the room at a constant speed, the force she exerts is vertical (to counter - act the weight of the box) and the displacement is horizontal. Since the force and displacement are perpendicular, the work done by the force she exerts on the box is zero according to the formula $W = F\cdot d\cdot\cos\theta$ where $\theta = 90^{\circ}$ and $\cos90^{\circ}=0$.

Answer:

Is no work done.
