Betsy uses an electric alarm clock to wake up for school. What energy transformation happens in the alarm clock to help her wake up?(1 point)
Responses
electrical energy converts to heat energy
electrical energy converts to heat energy
sound energy converts to kinetic energy
sound energy converts to kinetic energy
chemical energy converts to electrical energy
chemical energy converts to electrical energy
electrical energy converts to sound energy
electrical energy converts to sound energy
The correct answer is: electrical energy converts to sound energy
The correct answer is: electrical energy converts to sound energy.
Explanation:
In an electric alarm clock, the energy transformation that happens is that electrical energy is converted into sound energy. The clock uses electrical energy from a power source, such as a battery or a wall outlet, to generate vibrations in a small speaker or buzzer. These vibrations create sound waves that we hear as an alarm sound. So, when the alarm goes off, it is the conversion of electrical energy into sound energy that helps Betsy wake up.
