Because depending on what material the wave goes through it won't pick up that source of vibration.
sound is produced by vibrating a source threw air. +======================= Answer 2: For mechanical waves to traverse we need an elastic medium.
Sound is sensed only when vibrations produced by a source is transferred to the ear drum by means of a material medium. If such a medium is absent then sound cannot be heard. But vibrations of the source are always there.
Mechanical waves are produced when some kind of energy moves a substance, a material, or a "thing" within a medium that will conduct the mechanical energy of motion away from the source. And example of this would be a speaker, which takes an electrical signal and moves some kind of diaphragm with it. The diaphragm will move air or another fluid around it, and the sound waves will radiate from the device. If used in the vacuum of space, a speaker would be ineffective at transferring sound (mechanical) energy.
A transverse wave is a wave in which the medium vibrates at right angles to the direction of its propagation.There is no one unique source of energy that will produce a wave with this property.

Yes, it is true that the faster a sound source vibrates the higher the pitch.
Sound basically is produced by the vibration.When a particle vibrates very rapidly it produces a wave which carries energy.In air or any other medium sound is carried by to-and-fro movements of particles

The strings are the source for vibrations but the whole instrument vibrates to some extent when they are sounded.
Not in the literal sense of the words "Mechanical Energy". It depends on the source of the mechanical energy.If the source is renewable, like solar or wind generated electricity, then the mechanical energy is renewable.If the source is non-renewable, like electricity from burning oil, then it is non-renewable.
Yes. It is source of mechanical energy.
