Question

4* a piece of paper flew out of a school classroom with a gust of air. the paper, which was part of a quiz on forces, begins to fall to the ground. which of these is an unbalanced force acting on the paper as it falls? select all that apply.
a the paper has a mass of 1 gram.
b the paper has a weight of 0.01 newtons.
c the paper experiences friction as it falls.
d the paper has a surface area of 88 square inches.
e the paper experiences air resistance that slows its fall.

Explanation:

Unbalanced forces cause a change in motion. Weight is a force due to gravity and air - resistance/friction are forces that act against the motion of the falling paper. Mass and surface area are not forces.

Answer:

C. The paper experiences friction as it falls,
E. The paper experiences air resistance that slows its fall
