Final answer:
The force of gravity acting on the toolbox is equal to its weight, which is given as 95.0 N, regardless of the slope of the roof.
Step-by-step explanation:
The question asks about the force of gravity acting on the toolbox that is sliding down a roof. The angle of the roof or the slope at which the toolbox is sliding is irrelevant when we are simply asking about the force of gravity on the toolbox. The force of gravity, also known as weight, is a measure of the gravitational force exerted on an object. The weight of the toolbox, given as 95.0 N, is in fact the force of gravity acting on it. Therefore, the answer to the question is 1) 95.0 N, even though the toolbox is on an inclined plane, the gravitational force remains constant and equal to the weight of the object.
