The membrane that surrounds a certain type of living cell has a surface area of 5.1 x 10-9 m2 and a thickness of 1.4 x 10-8 m.
assume that the membrane behaves like a parallel plate capacitor and has a dielectric constant of 4.3.
(a) the potential on the outer surface of the membrane is +85.5 mv greater than that on the inside surface.
how much charge resides on the outer surface?
(b) if the charge in part (a) is due to k+ ions (charge +e), how many such ions are present on the outer surface?

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)
