A small sphere (emissivity = 0.648, radius = $r_1$) is located at the center of a spherical asbestos shell (thickness = 1.02 cm, outer radius = $r_2$; thermal conductivity of asbestos is 0.090 J/(s m C°)). The thickness of the shell is small compared to the inner and outer radii of the shell. The temperature of the small sphere is 683 °C, while the temperature of the inner surface of the shell is 348 °C, both temperatures remaining constant. Assuming that $r_2/r_1 = 7.03$ and ignoring any air inside the shell, find the temperature in degrees Celsius of the outer surface of the shell. Number 55 Units °C

The circuit in the figure incorporates a C-R network, a 9V battery and a 1pole, 2-way switch. All the values for resistors and capacitor are shown in the figure. The switch has been in position \( \mathrm{A} \) long enough to assume that the capacitor \( \mathrm{C} \) is fully charged. i) What is the magnitude of the charge stored by capacitor \( \mathrm{C} \) ? ii) If the switch is now thrown to position \( \mathrm{D} \), what is the time constant of the circuit ? iii) Calculate the time it takes for the capacitor to discharge to \( 2.5 \mathrm{~V} \). Show all your calculations.
