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 more than the energy input. the energy out of a system is always doubles the energy input.

Explanation:

According to the law of conservation of energy and the concept of energy efficiency (with energy losses like heat in real systems), energy output can't exceed input. The second statement claims output is always more (false, as losses occur), and the third says output always doubles input (also false, no such universal doubling). The first statement aligns with energy principles (considering inefficiencies, output ≤ input).

Answer:

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