Assume an axon has an internal diameter of 1μm and a myelin sheath 1μm thick. the internal specific resistance is 100 ω cm. for the myelin sheath use a dielectric constant of 8 and a transmembrane resistance of 2 x 105 ω cm2 . calculate the internal resistance per unit length

if you already have the answer to (a), then just work out how many periods there are in 1 minute, and that's the answer to (c).
