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.
Answer
Brief Explanations:
- For the first statement: Energy output can't always be double the input due to inefficiencies (like heat loss in systems), so it's inaccurate.
- For the second statement: Based on the law of energy conservation (and considering energy losses like friction, heat, etc. in real systems), the energy output can never exceed the energy input (in fact, it's often less due to losses), so this is accurate.
- For the third statement: Energy output can't always be more than input as energy is conserved and losses occur, so it's inaccurate.
