A long uniform rod of electrically resistive material has a resistance of Roriginal =1Ω. The rod is cut into N equal short pieces which are bundled side-by-side so that the short pieces are parallel to each other. The resistance of the bundled short rods is Rnew = 0.04Ω. What is the value of N? (i.e., how many pieces was the original rod cut into?
