Two metal bars with the same length and same cross-sectional area are placed between two tanks with temperatures of 400 K and 300 K. The thermal conductivity of the top bar is 200 W/mK. if the net energy transferred through the top bar in a given time interval is , what is the net energy transferred through the bottom bar during the same time interval? The left tank is at 400 Kelvin and the right tank is at 300 Kelvin. The top bar is labeled A with thermal conductivity k equals 200 watts per meter-kelvin, and the bottom bar is labeled B with k equals 400 watts per meter-kelvin.
