Answer:
1)diaphragm vibrations- sound waves
2) Changing magnetic fields- Electrical energy
3)sound waves- Mechanical energy
Explanation:
A changing magnetic field induces an electromotive force and then an electric field which contains electrical energy
Sound energy is a form of energy that can be heard by humans. Sound is an example of a mechanical wave because it consists of physically oscillatory elastic compression.
A diaphragm is a thin surfaced cone used to produce sound. It is caused to vibrate using electromagnetic energy.
Electric field , and if that’s wrong it should be electric force . Those are the only two that make sense
