Final answer:
The following diagrams accurately applies the Law of Conservation of Energy to a toaster in use is A. Electrical energy light sound
Step-by-step explanation:
The Law of Conservation of Energy states that energy can change form but is never lost. It means that the total amount of energy in a system remains constant. In the case of a toaster, the electrical energy from the power source is converted into thermal energy, light, and sound energy through various processes.
The diagram that accurately applies the Law of Conservation of Energy to a toaster in use is diagram a. In this diagram, electrical energy is converted into thermal energy, light, sound, and some electrical energy is dissipated as heat in the surroundings.
The Law of Conservation of Energy tells us that energy cannot be created or destroyed, only transferred or transformed. In the case of the toaster, the electrical energy is converted into various forms of energy as mentioned, but the total energy in the system remains constant. Therefore the correct answer is A. Electrical energy light sound
