Question

Answer

Supersonic speed refers to the speed that is greater than the speed of sound in air at sea level. In this case, the correct answer is option 'A', which states that supersonic speed is around 760 miles/hour.

Explanation:
- Supersonic speed is defined as any speed that exceeds the speed of sound. The speed of sound in air at sea level is approximately 760 miles per hour.
- The speed of sound is not a fixed value and varies depending on factors such as temperature, humidity, and altitude. However, for this question, we can assume that the speed of sound is approximately 760 miles per hour.
- When an object travels at supersonic speed, it is traveling faster than the speed at which sound waves propagate in the air.
- At supersonic speeds, shock waves are formed, which are characterized by a sudden increase in pressure and temperature. These shock waves can be heard as a sonic boom when the object passes by.
- Supersonic speeds are commonly associated with high-performance aircraft such as fighter jets and supersonic transport planes.
- It is important to note that the speed of sound is not a constant value and can vary in different mediums. For example, the speed of sound is faster in water than in air.

In conclusion, supersonic speed is defined as a speed greater than the speed of sound in air at sea level, which is approximately 760 miles per hour.
