What is the significance of the fact that the gravitational constant, g, is a very small number and that coulomb’s constant, k, is a very large number?
the comparison indicates that the electromagnetic force is a much weaker force than the gravitational force.

the comparison does not give enough information to determine which force is weaker because the forces are in different units.

Cells in the nervous system have a potential difference of 70 mv across the cell membrane separating the interior of the cell from the extracellular fluid. this potential difference is maintained by ion pumps that move charged ions across the membrane. is this an emf? select the correct answer and explanation. 1)no. the ion pumps cannot separate charges; thus, they cannot create a potential difference. 2)yes. the ion pumps cannot separate charges, but they still can create a potential difference. 3)yes. the ion pumps can actively separate charge; thus, they can create a potential difference. 4)no. the ion pumps can separate charges, but they cannot create a potential difference.
