The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Hypersonics**: Hypersonics refers to speeds that are significantly greater than the speed of sound. The speed of sound in air at sea level is approximately 343 meters per second, which is equivalent to about 1 Mach. 2. **Defining Mach**: The term "Mach" is used to represent the speed of an object relative to the speed of sound. For example, Mach 1 is the speed of sound, Mach 2 is twice the speed of sound, and so on. 3. **Identifying Hypersonic Speeds**: Hypersonic speeds are generally defined as speeds greater than Mach 5. This means that an object traveling at hypersonic speeds is moving at five times the speed of sound or more. 4. **Conclusion**: Therefore, hypersonics is connected with sound at speeds greater than Mach 5. **Final Answer**: Hypersonics is connected with sound of more than 5 Mach. ---
