Aheat-conducting rod consists of an aluminum section, 0.30 m long, and a copper section, .70m long. both sections have a cross-sectional area of 4  · 10⁻⁴m² the aluminum end of the rod is maintained at a temperature of 10°c, while the copper end is maintained at 160°c. what is the temperature at the point where the aluminum and copper sections meet? the thermal conductivity of aluminum is 205 w/m ∙ k, and of copper is 385 w/m ∙ k. 77°c 60°c 71°c 65°c 55°c
