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

Students in an introductory physics lab are performing an experiment with a parallel-plate capacitor made of two circular aluminum plates, each 11 cm in diameter, separated by 1.0 cm. how much charge can be added to each of the plates before a spark jumps between the two plates? for such flat electrodes, assume that value of 3×106n/c of the field causes a spark.
