The correct answer is: Energy transfers from Kiara’s fingers to the piano keys
The correct answer is: Energy transfers from Kiara's fingers to the piano keys.
When Kiara plays the piano, she uses her fingers to press the keys. As she applies force to the keys, her fingers and the keys move, resulting in the transfer of kinetic energy from her fingers to the piano keys. This is because kinetic energy is the energy of motion, and when Kiara's fingers move, they possess kinetic energy which is then transferred to the piano keys.
