In deep space, sphere a of mass 94 kg is located at the origin of an x axis and sphere b of mass 100 kg is located on the axis at x = 1.8 m. sphere b is released from rest while sphere a is held at the origin. (a) what is the gravitational potential energy of the two-sphere system just as b is released? (b) what is the kinetic energy of b when it has moved 0.60 m toward a?

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
