The speed of sound in air is 343 m/s, which converts to 1234 km/h.

What is the antonym of subsonic?

You could use "hypersonic." It is not a precise synonym, as subsonic is below the threshhold of hearing, whereas hypersonic would be above it. Supersonic would refer to velocity faster than the speed of sound, whereas subsonic also refers to velocities slower than those of the speed of sound. Sonic velocities are a consideration in jet aircraft design and with bullets and marksmanship. Subsonic rifle bullets tend to be more accurate than hypersonic ones


What is the most quiet Silenced pistol?

There is only a subjective answer to this question. To try and be speciffc, a pistol where the breach can be locked in the closed position would be about as quiet as you can get. An example of this would be a Thompson Center Contender single shot pistol. Another requirement for a successfully "silent" pistol would be a subsonic cartridge. This could be either a naturally subsonic cartridge, such as the .45 ACP or 9x17mm/.380 ACP, or reduced loadings of a naturally supersonic cartridge to make it travel at subsonic speeds.


How will you know that an object has kinetic?

The object would be moving.


What if there is no friction would a a moving object stop moving?

If there is no friction, a moving object would continue moving at a constant velocity in a straight line unless acted upon by an external force. Without friction to oppose its motion, the object would not come to a stop on its own.


Is an object in equilibrium moving?

An object in equilibrium is not moving, as all the forces acting on the object are balanced. If the object were to be in motion, it would no longer be in equilibrium as there would be an unbalanced force acting on it.


What is the difference between collided into and collided with?

Collided Into would be with a stationary object while "with" would be with another moving object.


If you drive onto a moving object how fast is your speed when you are on that moving object?

To drive onto a moving object (as, for example, up a ramp onto a moving trailer), you must be going faster than the object to move forward up the ramp, but when you come to a stop relative to the object, you will be moving with the object, so must be moving at the same speed. You must, in fact, decelerate to a stop on the object, or your faster approach speed would carry you through and beyond it.


What would happen if there was no friction to a moving object?

If there was no friction acting on a moving object, the object would continue moving indefinitely without slowing down or stopping. It would move in a straight line at a constant velocity unless acted upon by an external force.


What would happen if you doubled the force acting on a moving object?

Doubling the force acting on a moving object would cause the object to accelerate at a faster rate, leading to an increase in its speed. This is in accordance with Newton's second law of motion, which states that the acceleration of an object is directly proportional to the force acting on it.


What is the opposite of detonation?

The opposite of detonation is deflagration. Deflagration is a subsonic combustion process where the reaction moves through a substance slower than the speed of sound, in contrast to detonation which is supersonic.


How would you describe the energy of a moving object?

The energy of a moving object is typically described as kinetic energy, which is the energy an object possesses due to its motion. The kinetic energy of an object depends on its mass and velocity.


Does a moving object has impulse?

Would you like BBQ sauce with that.
