The mass density of copper is 8920 kg/m3 . The resistivity of copper is 1.7 × 10?8 Ω · m . A sheet of copper is 7 mm thick and hassurface dimensions of 5 cm × 21 cm . If the long edges are joined to form a tube 21 cm in length, what is the resistance be-tween the ends? Answer in units of Ω.full stars for correct answer thanks :)
