Question

energy transfer and kinetic energy quick check
when kiara plays the piano, how does kinetic energy transfer from one object to the other?
(1 point)
energy transfers from kiaras fingers to the piano keys
energy transfers from the piano keys to kiaras fingers
energy transfers from the piano pedals to the piano keys
energy transfers from the air to kiaras fingers

Explanation:

When Kiara plays the piano, her fingers are in motion (have kinetic energy). As she presses the piano keys, the kinetic energy of her fingers is transferred to the piano keys. The other options are incorrect: energy doesn't transfer from keys to fingers (fingers are the initiators of the motion here), from pedals to keys (the question is about fingers - keys interaction in the act of playing as described), or from air to fingers (there's no indication of air - related energy transfer in the context of playing the piano as presented).

Answer:

Energy transfers from Kiara’s fingers to the piano keys.
