Question

which of the following statements is accurate? the energy out of a system is always doubles the energy input. 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.

Explanation:

To determine the accurate statement, we analyze the principles of energy in systems. The law of conservation of energy (and practical energy transfer with inefficiencies, like energy loss as heat, sound, etc.) tells us that energy output cannot exceed energy input. The first statement (energy out doubles input) and the third (energy out is always more) go against energy principles. The second statement aligns with the idea that energy losses (e.g., friction, heat) mean output energy ≤ input energy.

Answer:

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