Question

which of the following statements is accurate? you can never get more energy out of a system than you put in. the energy out of a system is always doubles the energy input. the energy out of a system is always more than the energy input.

Explanation:

Step1: Analyze the first statement

According to the law of conservation of energy, energy cannot be created or destroyed. In a system, due to energy losses (such as in the form of heat due to friction etc.), the energy output \(E_{out}\) can never exceed the energy input \(E_{in}\). Mathematically, \(E_{out}\leq E_{in}\)

Step2: Analyze the second statement

If \(E_{out} = 2E_{in}\), it would violate the law of conservation of energy. There is no general physical principle that would make the output energy double the input energy. In fact, in real - world systems (non - ideal), \(E_{out}

Step3: Analyze the third statement

If \(E_{out}>E_{in}\), it would mean energy is being created within the system, which is not possible according to the law of conservation of energy.

Answer:

You can never get more energy out of a system than you put in.
