The situations where a net torque is being created by the interactions described are B, C, and D.
Explicación
## Step 1Net torque is the sum of all torques acting on an object. It is the product of the force and the distance from the pivot point. ## Step 2In the first situation, a ball is released in mid-air and falls downward. This is a case of free fall, where the only force acting on the ball is gravity. There is no net torque acting on the ball because the force of gravity acts directly downwards, not creating a torque.## Step 3In the second situation, a rubber ball is released on a ramp and begins rolling. The force of gravity and the normal force from the ramp create a net torque, causing the ball to roll.## Step 4In the third situation, a woman is climbing a ladder leaning against her house. The force of gravity and the normal force from the ladder create a net torque, causing the ladder to lean.## Step 5In the fourth situation, a man is being lifted upward by an elevator. The force of gravity and the normal force from the elevator create a net torque, causing the man to be lifted.
