Given the vectors P and shown on the grid, sketch and calculate the magnitudes of the vectors (a) M = P + and (b) K = 2Ē - 0.
Use the tail-to-head method and express the magnitude in centimeters
nitudes in centimeters with the aid of the grid scale

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?
