On its highest power setting, a microwave oven can increase the temperature of 0.429kg0.429kg of spaghetti by 45.0C45.0C in 120.s120.s.
Part (a)
Given that its specific heat is 3.76103J/(kgC)3.76103J/(kgC), a value which is about 90% that of water, what was the rate of energy absorption, in watts, by the spaghetti?
PP =
|
W
Part (b)
Find the average intensity of the microwaves absorbed by the spaghetti, in watts per squared meter, given that they are absorbed over a circular area 21.7cm21.7cm in diameter.
Part (c)
What is the peak electric field strength, in volts per meter, absorbed by the spaghetti?
Part (d)
What is the corresponding peak magnetic field strength, in teslas?
