A watering hose with a diameter of 2 cm is used to fill a 120 liter jar with water until it is full within 2 minutes. 1.25 m above the floor with the same flow rate find distance from water and nozzle.

The free body diagram shows a box being pulled to the left up a 25-degree incline. the magnitude of the normal force is

The graph describes the motion of an object. the object moves with from a to b. it from b to c. it moves with from c to d.

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
