The resistance of the wire in the type used in telephone lines is (35 Ohms per kilometer), and the mass of the wire is (5 kilograms per kilometer). The resistivity of the wire material is (1.95 x 10-82 m). What is the cross-sectional area of the wire? What is the resistance of a pulley containing (8 Km) of other wire made of the same material, but its mass is (20 kilograms per kilometer)?
