How did the frozen instruments produce sound and why did the different instruments produce different sounds? Use frequency and amplitude in your answer.

Sounds are produced by vibrating bodies so musical instruments produce sounds through vibration. Vibration is the to and fro motion of an object about their mean position.

Explanation:

Different frequencies of wave are produced from different structure of instruments and high amplitude of sound is produced due to loudness of sound which is generated by hard playing of musical instruments.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
