Yes, according to the law of conservation of energy, the total amount of energy in a closed system remains constant. This means that energy cannot be created or destroyed; it can only be transferred from one form to another. Kinetic energy is a form of energy that an object possesses due to its motion. When an object moves, its kinetic energy increases, but the increase in kinetic energy is offset by an equal decrease in potential energy or other forms of energy, ensuring that the total energy in the system remains constant. Therefore, kinetic energy conserves energy in a closed system.

No, kinetic energy does not store energy. Kinetic energy is a form of energy that an object possesses due to its motion. When an object moves, its kinetic energy increases, but when the object comes to rest, its kinetic energy is dissipated into other forms of energy, such as heat or sound. Kinetic energy is not stored, but rather, it is constantly in motion, and the amount of kinetic energy that an object possesses depends on its mass and velocity. So, while kinetic energy can be transferred from one object to another, it is not stored within an object.

The correct answer is C. Electrical energy from the outlet is converted to heat and light energy for the toaster when it is plugged in to an outlet in the wall and used to make toast. When the toaster is turned on, electrical energy flows from the outlet to the heating elements in the toaster, heating them up. The heat generated by the heating elements is then transferred to the bread through the toaster's grilling plates, which causes the bread to become toasted. Additionally, the toaster may also produce some light energy, such as a flashing light that indicates whether the toaster is on or off. Therefore, the energy transformation that occurs when a toaster is used involves the conversion of electrical energy to both heat and light energy.
