Asked by Julia
The Easy Bake Oven is a common toy for young children who want to emulate the process of cooking. Suppose this oven is plugged into a 120 V electrical outlet and "cooks" the food by using a 144 ohm resistor light bulb that converts electrical energy to both light and heat energy. If the light bulb converts 75% of the electrical energy to thermal energy, and the oven is used for a total of 15.0 hours during one month, to the nearest hundredth of a megajoule, how much thermal energy was produced?

Q=0.75V²t/R=
=0.75•120²•15•3600/144=4050000 J = 4.05 MJ
=0.75•120²•15•3600/144=4050000 J = 4.05 MJ
