It is desired to manufacture a uniform wire from M = 5.0 g of a
metallic material that obeys the Ohm law and whose density is
Ļm = 12.5 g / cm3. After having built it, using all the material,
it is found that the electrical resistance of the wire is R = 10.5
Ī©, that its length is L = 15.6 m; What is the resistivity of
unknown material in SI units?
