Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

Write down two additional questions about earth's magnetic field that will make your presentation more informative.

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?
