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?

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
