Question

Speed of supersonic aircraft is:-
A. Below speed of sound.
B. Equal to speed of sound.
C. More than speed of sound.
D. Equal to speed of light.

Answer 1

Hint: In order to solve this question we need to know about the basic idea of supersonic aircraft and how the speed of sound compelling with the speed of supersonic aircraft does.

Complete step by step answer:
When the vehicles will fly with the supersonic speed they are greater than the speed of sound. The speed of sound is about 1236 kilometers per hour at sea level. These speeds are referred to by Mach numbers. The Mach number is the ratio of the speed of the aircraft to the speed of the sound. The flight that is faster than supersonic aircraft. Supersonic speed is five times greater than the speed of the sound.

The supersonic aircraft speed is greater than 750 mph but less than 1500 mph, and the Mach number M is greater than one, 1 < M < 3. In supersonic aircraft, we remove the compressibility effects and the different air density because of expansions, flow choking and shock waves.
A bullet fired from a gun is an example of an object that flies at supersonic speeds. Military fighter aircraft also fly this fast. The space shuttle flies at supersonic speeds in the location of its mission.
Certainly the supersonic aircraft speed is the speed of a system that greater the speed of sound (Mach 1). When the objects fly in dry air of a degree of temperature of 20 °C at a level of sea, such speed is nearly 343.2 m/s. When the Speed of supersonic aircraft is greater than five times the speed of sound are often called as hypersonic. This condition occurs certainly somewhere between Mach 0.8 and Mach 1.2.

So, the correct answer is “Option C”.

Note:
Supersonic flight is one of the four speeds of flight. They are called the regimes of flight. The regimes of flight are subsonic, transonic, and supersonic and hypersonic. When vehicles fly at supersonic speed they are usually flying faster than the speed of sound.
