Question

Betsy depends on her electric alarm clock every morning to get up in time for school. What energy transformation happens in Betsy's alarm clock to wake her up in the morning? a chemical energy is converted to kinetic energy b sound energy is converted to electrical energy c electrical energy is converted to sound energy d electrical energy is converted to thermal energy

Answer 1

The correct answer is c) electrical energy is converted to sound energy.

In Betsy's alarm clock, electrical energy powers the inner workings of the clock, including the electronic circuitry and the speaker. When the alarm is triggered, the electrical energy is converted into sound energy, which produces the ringing or beeping noise that wakes Betsy up in the morning.
