What is the difference between transonic and subsonic speeds?
Transonic being past the speed of sound and subsonic is below the speed of sound.
The speed of an object traveling below the speed of sound is called?
subsonic
What best describes a flight approaching the speed of sound?
If accelerating to the speed of sound, the subsonic.
In divergent nozzle pressure will increase or decrease?
If the flow is subsonic the pressure will increase, if however it is supersonic the pressure will decrease.
What is ramming effect?
The atmospheric inlet air will convert from subsonic to supersonic condition at the duct area in ram jet engine.
What are subsonic signals?
Subsonic signals are sounds or vibrations that have a frequency lower than that which may be heard by the human ear as a discernable tone. Vibrations lower than 30 Hz (30 cycles per second) are considered subsonic.
What kind of sound is made by low frequency vibrations?
Low frequency sound is usually called "infrasound" analagous to the term "infrared" for light of less than visible wavelengths. Subsonic has also been used.
What is the antonym for the word subsonic?
The antonym for subsonic is supersonic.
What are sounds with frequencies below 20 hertz called?
Infrasonic.'Subsonic' and 'infrasonic' both define sound too low (in frequency or pitch) to be heard by humans without assistance.However, as 'subsonic' can also mean something traveling slower than the speed of sound, and 'infrasonic' only means frequencies below the audible range, 'infrasonic' is the better answer.
What is Subsonic Bullet?
Subsonic means "slower than the speed of sound" so a subsonic bullet is any bullet that travels slower than the speed of sound.
When was Subsonic - media server - created?
Subsonic - media server - was created on 2005-02-10.
What is the opposite of subsonic?
Supersonic
What is subsonic airflow?
lmfao
What Subsonic frequency and Hypersonic?
subsonic is lower than 20Hz, and hypersonic(aslo called ultrasonic freq.)is higher than 14000Hz-16000Hz(you cant hear ultrasonic freq.,some people hear 50-14000,some 150-16000, even some like me hear 20-16500)my specter of hearing freq.is 32-16347Hz(I have been on tests)
What is the difference between transonic and subsonic speeds?
Transonic being past the speed of sound and subsonic is below the speed of sound.
What is subsonic sound?
Another term for this is infrasonic, and it means pertaining to below hearing. There natural frequencies that humans can hear which are high: 20,000 Hz and low: 20 Hz. An average human cannot hear sounds below the frequency of 20 Hz. That is subsonic. Subsonic is a term also applied to aircraft that travel at speeds less than the speed of sound. Supersonic means it travels faster than the speed of sound.
What is the difference between subsonic and super sonic?
subsonic is moving below the speed of sound, supersonic is faster than speed of sound
