On its highest power setting, a microwave oven increases the temperature of 0.350 kg of spaghetti by 45.0°C in 100 s.
(a) What was the rate of power absorption by the spaghetti, given its specific heat is 0.900 kcal/kg·°C?
(b) Find the average intensity of the microwaves, given they are absorbed over a circular area 20.0 cm in diameter.
(c) What is the peak electric field strength of the microwave?
(d) What is its peak magnetic field strength?
