ENDOCRINE ORGANS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Sound is caused by ____
A
molecules
B
vibrations
C
people
D
space
Explanation: 

Detailed explanation-1: -Sound is a type of energy made by vibrations. When an object vibrates, it causes movement in surrounding air molecules. These molecules bump into the molecules close to them, causing them to vibrate as well. This makes them bump into more nearby air molecules.

Detailed explanation-2: -Sound is caused by the simple but rapid mechanical vibrations of various elastic bodies. These when moved or struck so as to vibrate, communicate the same kind of vibrations to the auditory nerve of the ear, and are then appreciated by the mind.

Detailed explanation-3: -Vibration is the backward and forward movement of a body. Sound is caused by vibration that makes particles in the air form sound waves.

Detailed explanation-4: -The vibration of an object creates sound waves that travel to our ears. What are vibrations? Explanation: Vibrations are quick back-and-forth movements that create sound waves that travel to our ears for us to hear.

Detailed explanation-5: -We are lucky that sound makes vibrations; otherwise, we would have no hearing. Sound, which essentially is just a vibration of the air, makes the little membranes in our ears – the eardrums – vibrate. And these vibrations generate signals that are transmitted to our brains to make us hear.
