Question 5 (1 point) A student carries out an experiment to determine the resistivity of an unknown material. She picks several wires made of that material. Each wire has a length of 1.00 m and various diameters of the cross section, d. She applies a potential difference V at the ends of the wire such that the current through each wire has the same value, /= 0.300 A. The student collected the data shown in the table below, in which the diameter is in millimeters and the voltage in volts. d (mm) V (V) 0.6 0.028 0.9 0.012 1.2 0.007 1.5 0.004 1.8 0.003 2.1 0.002 Analyze this data set to identify the material. Pick the material from this list: http://hyperphysics.phy-astr.gsu.edu/hbase/Tables/rstiv.html Silver Copper Aluminum Tungsten Iron Platinum Manganin O Lead ONichrome
