A heat conducting rod, 1.60 m long, is made of an aluminum
section, .9 m long, and a copper section, .7 m long. both sections
have a cross-sectional area of .0004 m2. the aluminum
end and the copper end are maintained at temperatures of 30 degrees
celcius and 170 degrees celcius, respectively. the thermal
conductivity of aluminum and copper are 205 and 385 W/m*K,
respectively. the rate at which heat is conducted in the rod is
closest to:
11W
12W...
