what is the energy transformation that occurs when a smoke alarm goes off?
a sound to light
b potential to electrical
c electrical to potential
d electrical to sound
The correct answer is d) electrical to sound.
When a smoke alarm goes off, it typically detects smoke particles in the air and triggers a small electrical current or voltage. This electrical signal then activates a buzzer or speaker within the smoke alarm, which converts the electrical energy into sound energy. The sound energy produced by the smoke alarm is what alerts individuals to the presence of smoke or a potential fire.
