How much fiberglass insulation (k = 0.035 W/m*K) is needed to guarantee that the outside temperature of a kitchen oven will not exceed 43 degrees Celsius? The maximum oven temperature to be maintained by the conventional type of thermostatic control is 290 degrees Celsius, the kitchen temperature may vary from 15 to 33 degrees Celsius, and the average heat transfer coefficient between the oven surface and the kitchen is 12 W/m2*K.

  What is the frequency of the voltage source in khz

A sinusoidal voltage source is zero at t = 0.2 microseconds and is "going positive" at that point, meaning that v(t') > 0 for t' = 0.21 microseconds. Furthermore, the voltage at t = 0 is -28 milliVolts and its next zero is at t = 8.2 microseconds
