Ana+ ion moves from inside a cell, where the electric potential is -63 mv, to outside the cell, where the potential is 0 v. what is the change in the ion's electric potential energy as it moves from inside to outside the cell?

Explanation:

The change in the ion's electric potential charge as it moves from inside to outside the cell is:

where

q is the charge of the ion

is the potential difference

- The charge of the ion is +e, since it is positively charged, so

- The potential difference is

So, the change in the ion's electric potential energy is

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
