- A. Increase the amount of wasted energy
- B. Reduce unwanted energy transfers
- C. Use thicker materials for insulation
- D. Increase friction in moving parts
Answer
Reduce unwanted energy transfers
Explanation
The correct option is "Reduce unwanted energy transfers". Reduce unwanted energy transfers is right because it directly matches Efficiency: (HT only) Explain how reducing unwanted energy transfers improves efficiency.. 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 Improvement
Students often think that reducing unwanted energy transfers means eliminating all energy loss, which is impossible in real systems.
Clarify that while energy losses can be minimized, no system can be perfectly efficient due to inherent energy dissipation.
