Explain how sound is produced by your school bell? 2. Why are sound waves called mechanical waves? 3. Suppose you and your friend are on the moon. Will you be able to hear any sound produced by your friend?
Answers
Answer:
Brainliest please,
Explanation:
Ans:1
When the school bell is struck with a hammer, the hammer hits the gong again and again that causes compressions and rarefactions in the air. These vibrations travel in the air in the form it starts vibrating and as a result sound is produced in the bell.
Ans:2
Mechanical wave- Waves that require a medium ( solid, liquid or gas) to travel are known as mechanical waves. ... So, sound waves are longitudinal. Also, it cannot travel through a vacuum and requires a medium (solid, liquid, or gas) to travel. Thus, a sound wave is called a mechanical wave.
Ans:3
The moon has no air or atmosphere at all. It is all vacuum. Since sound cannot travel through a vacuum, therefore we cannot hear the sound produced by our friend.
Answer:
Sonarity
Explanation:
this is because sonarity is produced over it the situation where there will be the producing the sound where the waves from the bell and heard to the eardrum of our ear.
because sound waves stores the sound in the form of potential and travels in the form of mechanical energy hesns the waves travels in one form of direction to reach the waves
hence in the space there will be no air hence vaccum is present in the space so we cannot here the sound traveld in the space
