In a physics experiment, scientists use the equation R = to represent the resistance in a conductive wire. Rewrite this formula to represent the length of the wire in terms of R, p, and A where p represents the resistivity and A represents the cross-sectional area of the wire. Use your equation to determine the Length of a wire with a resistance of 7 , a resistivity of R. -8 2.44 x 10 m, and a cross sectional area of 0.02 m 0.02m L = length p = resistivity A = area = P=2.441021 R = P 4=76 A MA R PL A
