on its highest power setting, a microwave oven can increase the temperature of 0.400 kg of spaghetti by 45.0∘C in 120 s.
(a) What was the rate of power absorption by the spaghetti, given that its specific heat is 3.76×103J/kg⋅∘C?
(b) Find the average intensity of the microwaves, given that 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?
