A 50.0-g sample of a conducting material is all that is available. The
resistivity of the material is measured to be 11~ 10-8 ƒ¶m and the density is 7.86 g/cm3. The
material is to be shaped into a solid cylindrical wire that has a total resistance of 1.5 ƒ¶.
a) What length of wire is required?
b) What must be the diameter of the wire?
