The correct answer is cutting paper because it is an example of a physical change. A physical change is a change a change in the properties of matter that does not change the identity of the substance. On the other hand, chemical change is a change where the substance changes in identity after undergoing a process..

Polly is pushing a box across the floor with a force of 30 N. The force of gravity is –8 N, and the normal force is 8 N. Which v
andrew11 [14]

The answer is -30 N

The explanation:

- to make the box move. so,the horizontal force must be greater than the frictional force.

-and when the horizontal force applied is 30 N. So, the box will remain stationary if the frictional force is equal in magnitude but opposite in direction to the horizontal force. means frictional force = -30 N

This is also being indicate that vertical force due to gravity is equivalent to the normal force when gravity force = 8 N and normal force =8 , meaning the box does not move vertically.
