A cylindrical rod of cross-sectional area 5.0mm2 is made by joining a 0.30m rod of silver to a 0.12m rod of nickel. The silver end is maintained at 290K and the nickel end at 440K. given the thermal conductivities of silver and nickel are 0.42kWm-1K-1 and 91Wm-1K-1 respectively, calculate:

the temperature of the join under steady conditions, and
b the rate of conduction of heat down the rod
State any assumptions you need to make.
