Apotential difference δ exists between the inner and outer surfaces of the membrane of a cell. the inner surface is negative relative to the outer surface. of 2.40×10−20 j of work is required to eject a positive potassium ion (k+) from the interior of the cell, what is the magnitude of the potential difference (in millivolts) between the inner and outer surfaces of the cell?

correct it is c.) b b

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
