A cylindrical resistor is 9.3 cm long and has a resistance of 48 N measured end-to-end. The material is melted down and recast* into a new thicker cylindrical resistor that is 4.0 cm long. What is the resistance of the new resistor? Give your answer in units of N. *Assume in the recasting process, the material is perfectly preserved such that the new resistor has the same resistivity and volume as before.
