A student measured the potential difference between two ends of a straight wire of length 0.50 m and diameter 2.0 mm for different electric currents running through the wire. The student plotted the potential difference (in volts) as a function of the electric current (in ampères) with the goal of calculating the resistivity of the material. The graph, including the trendline, is shown in Figure 2b. Based on this experiment, the resistivity of the material is: 1.68 x 10-6 Q m 4.19 x 10-5 0 m 1.68 x 1052 m 0.00419 2 m 4.19 x 10-7 o m O 0.00168 Q m 1.33 x 10-7a m 1.33 x 10-8 o m AMoving to th e poxt question provopts cha ngos te this answor
