As I pull a rope connected to a box at constant speed up a frictionless slope,pulling parallel to the slope,the tension in the rope will be:
A)greater than the tension would be if the box were stationary.
B)greater than the weight of the box.
C)equal to the weight of the box.
D)less than the weight of the box.

When pulling a box up a frictionless slope at constant speed, the tension in the rope must balance the component of the box's weight parallel to the slope. Since this component is less than the total weight of the box, the tension will be less than the weight of the box.
