basic component of matter, it is composed of a nucleus which is the central part, the protons and electorns

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.

The energy equivalent of the rest mass of an electron is

Large electric fields in cell membranes cause ions to move through the cell wall. the field strength in a typical membrane is 1.0 x 10 7 n/c. what is the magnitude of the force on a calcium ion with charge +e? what is its acceleration? is it possible for a particle with the same charge as as calcium to have a different acceleration if placed at this location? what would change the acceleration: mass of the particle? diameter of the particle?
