Final answer:
If 2000 J of energy is input into the electric fire every second and assuming no energy loss, then 2000 J of energy is also transferred out every second.
Step-by-step explanation:
The amount of energy transferred out of an electric fire every second can be determined by considering the principle of energy conservation. The electric fire is an energy conversion device, turning electrical energy into heat. Assuming that the system is 100% efficient and there is no energy loss, the energy transferred out would equal the energy input. Therefore, if 2000 J of energy goes into the electric fire every second, then 2000 J of energy is transferred out every second as well, provided there is no loss to the surroundings.
