Answer :
Final answer:
Brian should use a buzzer to replace the device in the alarm clock because it effectively converts electric energy into sound energy. Other options either provide power or convert energy differently but are not suitable for this purpose. The buzzer is specifically designed for sound production from electric energy.
Explanation:
Identifying the Correct Device for Sound Energy Conversion
In this scenario, Brian is tasked with repairing an old alarm clock and needs a device that converts electric energy into sound energy. Among the options provided:
- A. battery - This provides power but does not convert energy.
- B. buzzer - This device is specifically designed to convert electric energy into sound energy, making it the correct choice.
- C. motor - While it converts electric energy into mechanical energy, it does not produce sound.
- D. switch - This merely opens or closes a circuit and does not convert energy.
Therefore, Brian should use a buzzer to replace the device in his alarm clock, as it will fulfill the requirement of converting electric energy to sound energy.
