Polarized sunglasses work by a. blocking light waves that vibrate in one plane. b. gradually refracting light as it passes through the lenses. c. bending light as it passes from air into the lenses. d. reflecting most of the light that strikes the sunglasses.

An electron is ejected into a horizontal uniform e⃗ field at a parallel horizontal velocity of v0. assume the electron's initial position x0, initial velocity v0, time t, magnitude of electric field e, electron's mass m, and the magnitude of the electron's charge |e|. ignore the force that earth exerts on the electron. assume the e⃗ field is in the same direction as the initial velocity. part a define the equation for the electron's velocity. express your answer in terms of the variables v0, |e|, t, e, and m.
