What forces are acting on a parachute as it falls through the air?
A
Upthrust and air resistance
B
Friction and magnetism
C
gravity and air resistance
D
magnetism and water resistance
Explanation: 

Detailed explanation-1: -The main forces acting on a parachute are gravity and drag.

Detailed explanation-2: -The force working against gravity that a parachute takes advantage of is called air resistance or drag. When a skydiver releases a parachute, it unfolds and quickly traps air molecules, effectively increasing the amount of air resistance and slowing the skydiver to a safe descent speed.

Detailed explanation-3: -On leaving the plane the only force acting is weight/gravity acting downwards as the parachutist falls air resistance acts upwards. The weight is greater than air resistance so the resultant force is downwards, the parachutist accelerates.
