Suppose you wish to fabricate a uniform circular wire (imagine a long solid cylinder) from a mass m of a metal with density pm and electrical resistivity p. If the wire is to have a resistance of R and all the metal mass m is to be used, what must be (a) the length and (b) the diameter of this wire? Use the following parameters:
