While II is decreasing, what is the direction of the net force that the wire exerts on loop AA? While is decreasing, what is the direction of the net force that the wire exerts on loop ? The wire exerts a downward force on loop AA. The wire exerts an upward force on loop AA. The wire exerts no force on loop AA.

Avery hard rubber ball (m = 0.5 kg) is falling vertically at 4 m/s just before it bounces on the floor. the ball rebounds back at essentially the same speed. if the collision with the floor lasts 0.05 s, what is the average force exerted by the floor on the ball?

A2k pendulum has a speed of 1 m/s at a height of 1/2 meter

With the simplified model of the eye, what corrective lens (specified by focal length as measured in air) would be needed to enable a person underwater to focus an infinitely distant object? (be careful-the focal length of a lens underwater is not the same as in air! assume that the corrective lens has a refractive index of 1.62 and that the lens is used in eyeglasses, not goggles, so there is water on both sides of the lens. assume that the eyeglasses are 1.90
