dish of lasagna is being heated in a microwave oven. The effective area of the lasagna that is exposed to the microwaves is 2.89 x 10^-2 m2. The mass of the lasagna is 0.680 kg, and it's specific heat capacity is 3920 j /(kg C degrees). The temperature rises by 87.1 degrees Celsius in 6.7 minutes. What is the intensity of the microwaves in the oven?
