The next two problems both relate to the following situation.
A wire 1 meters long and d mm in diameter has a resistance R ohms. A potential difference can be applied by connecting the ends of the wire to a battery with voltage V.
If l = 5.4 m, d = 4.8 mm, R = 124 Ω, and V = 11.4 V, what is the resistivity of the wire's material?
Report your answer in units of 10^(-5) Ω*m. For example, if your calculation produces a value of 1.23 x 10^(-4) Ω*m, first convert units as 1.23 x 10^(1)(x 10^(-5) Ω*m) = 12.3 x 10^(-5) Ω*m, then enter your answer as 12.3.
