He steady-state temperature distribution in a one-dimensional wall of thermal conductivity 50 W/m · K and thickness 50 mm is observed to beT(°C) =a+bx2, wherea= 200°C, b= −2000°C/m2, andxis in meters. One side of the wall is at x= 0 and the other at x= 0.05 m. (a)What is the heat generation rate qin the wall?
