Question
An object is said to be moving at a supersonic speed when its speed is ____ the speed of sound in a medium.
- Less than
- Greater than
- Equal to
- Any of the above
Hint:
An object is said to be moving at a supersonic speed when its speed is greater than the speed of sound in a medium.
The correct answer is: Greater than
- A supersonic speed is the rate of speed that is more than the speed of sound.
- When an object is said to be moving at a supersonic speed, it means it is moving faster than the speed of sound in a medium.
- The speed of sound in a medium will be less than the supersonic movement of an object.
