Describe the net force and explain how its demonstrated

Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz.

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?

The unit of resistivity is the: ohm ohm-cm volt coulomb
