Thermal question. A system has two thermal layers. The first layer has a Rth 0.5 K/W, and Cth 0.8 J/K, and the second layer has a Rth 0.2 K/W, and Cth 0.4 J/K. The ambient air temperature is 50 °C. The power dissipation in the system is 100 W. What is the temperature of the second layer 5 s after a system is switched off? Please do not include any units in your answer.
