Which are properties of both a gas and a plasma? Check all that apply. can change shape to conform to a container
has a rigid shape that does not change easily
is made up of free-moving ions and electrons
is compressed more easily than other states
has particles that can wiggle but cannot move
has particles that move freely from place to place
will expand to completely fill a closed container

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?
