[@kanaksingh176]

Nice question.....

[@RohitKumar-nh6pj]

Hlo

[@tanuthakur18]

Actually it has its limited orbit to find a medium and sound can be heard there and I think they have to cross the orbit to listen and record the voice ❤❤❤❤

[@tanuthakur18]

☝🏻 this is the answer of your question And hope it will help you 😊

[@priyansucreation5699]

Sound not only help comunicating with others bro,

[@priyansucreation5699]

Sound is a form of energy which produced by the vibration of objects

[@NehaMustaq]

Wave helps propagate energy one location to another location without transfer of metal

[@sumanmadheshiya8084]

It is a form of energy that gives us sensation of hearing

[@SunilSolanke-id9nk]

The maximum displacement of the vibrating object from Central position is known as amplitude

[@shivprasad-ki9jb]

Mean position

[@RAJANIKUMARI-gc7il]

The maximum displacement of the particle from its mean position is called amplitude

Q1: Ans : Sound is a form of energy , which produces the sensation of hearing in our ears . It is a vibration that propagates through a medium in the form of a mechanical wave . It is generated by a vibrating body. The medium through which it propagates can either be a liquid , a solid or a gas.
