Answer:
1 . Organ of hearing - The INNER EAR consists of a spiral shaped structure known as the cochlea (means snail-shell). Within the cochlea sits the organ of hearing where we have thousands of tiny cells, known as hair cells
2 . Movement about a fixed point - RATIONAL MOTION is motion around a fixed point. An example of this would be the hands of a clock moving around their fized point in the center, or a swing set. An example of an object that undergoes both would be a football.
3 . The close together part of the wave - COMPRESSIONS places where particles of a medium crowd closer together are called compressions, and places where the particles spread farther apart are called rarefactions.
4 . Determined by the amplitude of the sound wave - The AMPLITUDE of a sound wave determines it relative loudness.
5 . Vibration that travel through the air or another medium - Vibration that travel through the air or another medium and can heard when they reach a person's or animal's ear is called SOUND.
