Question: You have a 76.3-cm-long copper rod with a rectangular cross section of dimensions 5.05 cm by 7.95 cm. You maintain the ends of the rod at 57.5°C and 95.3°C, but otherwise insulate the rod from its environment.
Part A: Find the heat current through the rod.
I need help to determine the heat current through the rod and the thermal conductivity of copper is 385 W/(m•K).
