(a) If you ride in an elevator moving upward with constant speed, is your apparent weight greater than, less than, or equalto your actual weight, mg? (b) Which of the following is the best explanation for your prediction?I. The elevator is moving upward. This will cause a person to press down harder on the floor, giving an apparent weightgreater than mg.II. The elevator moves with zero acceleration, and therefore the apparent weight is equal to mg.III. Because the elevator is moving upward it is partially lifting the person, resulting in an apparent weight less than mg
