Alfredo makes a diagram to organize his notes about charging objects.
which statement should he place in the region marked x?
it does not involve touching the objects together.
the objects develop opposite charges.
electrons move between objects.
the objects have the same charge.

Charge is distributed along the entire x-axis with uniform density λ. how much work does the electric field of this charge distribution do on an electron that moves along the y-axis from y = a to y = b? (use the following as necessary: a, b, ε0, λ, and q for the charge on an electron.)

Efficiency is the ratio of to for a system a)power in to power in b)power in to power out c) power out to power out d) power out to power in
