Final answer:
The correctly matched energy transfer is Fusion in the sun: nuclear to light and heat. Fusion is a nuclear process, not chemical, as initially suggested. The other examples incorrectly describe the direction of energy conversion.
Step-by-step explanation:
The question asks which energy transfer is correctly matched. The correctly matched energy transfer is:
Fusion in the sun involves the combination of hydrogen nuclei to form helium, releasing a tremendous amount of energy in the form of light and heat. This process is a form of nuclear energy, not chemical energy as initially listed in the provided options.
A solar calculator converts light directly into electrical energy, not the other way around. A ceiling fan converts electrical energy into mechanical, not thermal to mechanical. Lastly, playing a clarinet converts mechanical energy from your breath and fingers into sound, not mechanical to sound as it implies that mechanical energy is the output, not the input.
