Copper wire gas resistivity density=1.7x10^-8 omega•m what at 20 degrees X and it has a temps tire coefficient a=3.9x10^-3 K^-1. A solid cylinder of copper of length L=75 cm and diameter D=1.5 mm has one end held at T1=15 degrees C and the other is held at T2=210 degrees C. The temperature increases linearly between the two ends of the cylinder. Part (a) Consider a thin slice of the copper cylinder of thickness DX that is located a distance X from the left of the cylinder. Write an equation for the temperature of this place in terms of the variables x,L,T1, and T2. Part (b) determine the total resistance in miliohms.
