The correct Answer is:
To find the velocity of sound in a vacuum, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Sound Waves**: - Sound is a mechanical wave that requires a medium (solid, liquid, or gas) to travel. It cannot propagate through a vacuum, which is an absence of matter. 2. **Definition of Vacuum**: - A vacuum is a space devoid of matter. Since sound waves rely on particles to transmit vibrations, they cannot move through empty space. 3. **Conclusion**: - Since sound cannot travel in a vacuum, the velocity of sound in a vacuum is 0 m/s. 4. **Selecting the Correct Option**: - Among the given options (0, 330 m/s, 360 m/s, 660 m/s), the only correct answer is 0 m/s. ### Final Answer: - The velocity of sound in vacuum is **0 m/s**. ---
