c
surface area
d
mass
1 answer
The correct answer is (c) surface area. When a parachute is open, it creates a large surface area in contact with the air, resulting in an increase in air resistance or drag. This increase in drag slows down the skydiver's descent. If the parachute were not opened, the skydiver would continue to fall at a faster speed due to the force of gravity.
