According to Newton's first law of motion, what would happen to a car traveling at a constant velocity of 55 MPH to the west in the absence of an unbalanced force?

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?

Convection occurs when thermal energy is transferred by the movement of
