An electron is initially at rest in a uniform electric field having a strength of 2.1 × 10^6 v/m. it is then released and accelerated by the presence of the electric field. part a) what is the change in the electron’s kinetic energy, in kiloelectron volts, if it travels over a distance of 0.325 m in this field?
part b) over how many kilometers would it have to be accelerated in the same electric field to increase its kinetic energy by 65 gev?
part c) in what direction did the electron move?

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
