How fast is the speed of sound at an elevation of 20000 feet?
Forget the altitude. Care about the temperature!The speed of sound is dependent on the temperature and not on the air pressure of the altitude. At 20 degrees celsius or 68 degrees Fahrenheit the speed of sound is 343 m/s or 1236.3 km/h or 1126.7 ft/s or 667.1 knots.Scroll down to related links and look at "Speed of sound - temperature matters, not air pressure".Here is an easy calculator if you know the temperature. Do not care about the altitude!Scroll down to related links and look at "Calculation of the Speed of sound in air and the important temperature".Asume a temperature of -70 degrees Celsius for a height of 44,000 feet.
What factor will increase the speed of a sound wave in the air?
Speed of sound would increase as the temperature of the air increases Speed of sound increases as humidity of air increases Speed of sound is affected by the density of the air. As density increases velocity of sound decreases
How many times faster than the speed of sound can you travel?
No real limit, up to the speed of light. The Apollo astronauts traveled at ABOUT 32 times the speed of sound on their trip to the moon. That is the fastest yet.
What is the name of speed of sound?
The speed of sound is a Mach. 1 Mach for a particular medium is the distance that sound would travel through that medium in 1 second.
What if the speed of sound in air depended on the source of the sound?
You would then hear some sound sooner than others.
Two planes are flying at the speed of sound Plane X is flying at an altitude of 6000 feet and plane Y is flying at an altitude of 15000 feet which is flying faster?
As altitude increases (to about 35,000 ft) air density, pressure and temperature all drop. As density decreases speed of sound increases, but with drop in pressure it drops; these two practically cancel each other out. As temperature drops, speed of sound drops. Thus at 15,000 ft the speed of sound is slower than at 6,000 ft so plane X is flying faster than plane Y.
What speed is Mach 2.5?
Mach is a unit of speed based on the speed of sound (which varies with altitude and pressure). Mach 1 is the speed of sound, 340.29 m/sec or about 761.2 mph at sea level. Mach 2.5 would be 2.5 times as fast, or about 1900 mph.
What would happen if the diaphragm of a speaker exceeded the sound barrier?
Exceeding the sound barrier refers to speed of travel, not loudness of sound. A speaker cannot "exceed the sound barrier".
What is the speed of sound at sea level plus one meter?
The speed of sound at sea level is around 343 m/s. Adding one meter to the elevation would not significantly change the speed of sound, as it is mainly influenced by factors like temperature and humidity, not altitude. So, the speed of sound at sea level plus one meter would still be approximately 343 m/s.

What would happen first hear a gun shot or see a gun shot?
See it- speed of light, then hear it- speed of sound is MUCH slower.
What would happen if could make sound move at the speed of light?
First of all, how would you go about to do that? I don't think that is even possible.
What does Mach 3.2 mean?
Mach 3.2 refers to traveling at 3.2 times the speed of sound. The speed of sound varies depending on altitude and temperature, but at sea level and room temperature, it is approximately 343 meters per second. Therefore, Mach 3.2 would be about 1,100 meters per second.
How fast does an airplane have to be moving to produce a sonic boom with 30 degree celsius?
The speed of sound in air at 30 degrees Celsius is around 354 m/s. To produce a sonic boom, an airplane would have to be traveling at a speed faster than the speed of sound, typically around 1.2 to 1.4 times the speed of sound, depending on various factors such as altitude and aircraft configuration.
What is a Concorde's max altitude?
It cruised about 60,000 feet, so that's about as high as it would go.
How long would it take to get to mars traveling at the speed of sound?
The speed of sound is only 768mph.
How many miles per hour is mach 8?
Mach is not an absolute speed but a relative speed. The Mach value of an object is the ratio of the speed fo the object travelling through a medium to the speed of sound travelling through the same medium. Now sound travels faster in denser mediums so the speed of sound in [dense]air at sea level is greater than the speed of sound at high altitude. So Mach 2 in the air at sea level is faster than Mach 2 at high altitude. But Mach 2 under water is very much faster. However, most people are ignorant about the proper meaning of Mach and assume that it is simply related to the speed of sound at sea level at normal temperature/pressure/humidity - approximately 760 miles per hour. In that case Mach 8 would be 6080 mph.
