Along cylindrical shell with a radius of 1cm has a charge uniformly distributed on its surface. if the magnitude of the electric field at a point 8cm radially outward from the axis of the shell is 85 n/c, how much charge is distributed on a 2m length of the charged cylindrical surface?

Acertain half-reaction has a standard reduction potential e_red^0 = -0.94 v. an engineer proposes using this half-reaction at the cathode of a galvanic cell that e must provide at least 1.00 v of electrical power. the cell will operate under standard conditions. a. is there a minimum standard reduction potential that the half-reaction used at the anode of this cell can have? b. is there a maximum standard reduction potential that the half-reaction used at the anode of this cell can have?
