Answer 1

a) gong

b) the membrane

c) strings

d) strings

e) air

Answer 2

Answer:

An electric bell produces sound as and when the bell vibrates as the arm hits it( due to the generation of electromagnetic current).

A loudspeaker- The motor vibrates a diaphragm that in turn vibrates the air in immediate contact with it, producing a sound surge corresponding to the pattern of the original speech or music signal.

For a piano, the strings joggle as the hammers connected to the piano keys hit them.

For a violin, the bow causes the strings to joggle, and those vibrations are transferred to the body of the violin, which also converts these vibrations to the air, therefore generating sound.

For a flute, the air inside the spherical column( the flute) vibrates, at a frequency depending upon what corridor you have covered while playing it.
