Explain clearly how the electrophorus works, being careful to include in your explanation a clear description of why the charge on the plate is not used up in the process of charging the metal disk

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.

What is part of a line has one endpoint and continues in one direction?

Aplane's average speed between two cities is 600 km/h. if the trip takes 2.5 hours, how far does the plane fly?
