The charge on one electron is 1.6 x 10^-19 Coulombs. The electron beam in an oscilloscope has 3.4 x 10^7 electrons flowing per second and the accelerating voltage is 15 kV. What is the effective resistance of the space the electrons flow through?

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
