A 0.2-cm-thick, 15-cm-long and 10 cm wide circuit board houses electronic components on one side that dissipate a total of 15 W of heat uniformly. The board is impregnated with a conducting metal fillings and has effective thermal conductivity of 15 W/m. K. All the heat generated in the components is conducted across the circuit board and is dissipated from the back side of the board to medium at 20 oC with heat transfer coefficient of 50 W/m2.K. 1) Determine surface temperature of the two side of the board. (2 points) 2) Now .1-cm-thick, 10-cm-high and 15-cm-long aluminum plate (k
