Which design modification would best address this problem?
A) Decreasing the diameter of the parachute.
B) Replacing the plastic connectors with heavier metal ones.
C) Replacing the rigid wooden box with a lighter cardboard box or increasing parachute size.
D) Reducing the amount of foam liner inside the box.
Question 16:
What will happen to the gravitational force between two objects if the distance between them is halved?
A) The gravitational force will become one-half as great.
B) The gravitational force will become two times as great.
C) The gravitational force will become four times as great.
D) The gravitational force will become eight times as great.
