Final answer:
In Physics, electrical energy can be converted into sound by devices such as a trumpet, stereo speaker, and microphone.
Step-by-step explanation:
In Physics, several devices can convert electrical energy into sound. These include a trumpet, a stereo speaker, and a microphone. The trumpet converts the air vibrations produced by the player's lips into sound waves, while a stereo speaker converts electrical signals into audible sound. Similarly, a microphone converts sound waves into electrical signals.
