Question
- A. By increasing wasted energy
- B. By reducing unwanted energy transfers
- C. By creating more energy
- D. By using thicker materials
Answer
By reducing unwanted energy transfers
Explanation
The correct option is "By reducing unwanted energy transfers". By reducing unwanted energy transfers is right because it directly matches Efficiency: Explain why no real energy transfer is perfectly efficient.. The other options are less suitable because they change the required Physics relationship, confuse the relevant energy store or use a distractor that does not answer the question.
Common mistake
Misunderstanding Efficiency
Students often believe that energy transfers can be perfectly efficient in real-world scenarios.
Emphasize that all real energy transfers involve some energy dissipation, making perfect efficiency impossible.
