What is the speed of sound in stainless steel?
Sound velocity in steel - 5960 m/s Sound velocity in Stainless steel - 5760 m/s
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.
Why is it easier to break the sound barrier at higher altitudes?
The speed of sound changes only with temperature. The altitude and the atmospheric pressure has no influence. Usually the temperature goes down with higher altitude. Notice: The speed of sound changes with temperature and a little bit with humidity − but not with air pressure (atmospheric pressure). The words "sound pressure at sea level" are incorrect and misleading. The temperature indication, however, is absolutely necessary. The speed of sound in air at 20 degrees Celsius (68 degrees Fahrenheit) is 343 metres per second. That is 1126.547 feet per second.
How fast is quicksilver?
Originally capable of running at the speed of sound; 768 mph Yes he is originally capable of running the speed of sound, but at one point, he was captured by the High Evolutionary and his powers were upgraded by its Isotope E and his Speeds at that moment rivaled The Flash ( DC universe, aka Fastest Man Alive).
Why is the velocity of sound greater in solids than in gas or liquid?
The speed of sound is greater in solids because the molecules of solids are so much closer together - it takes less time, then, for the sound waves to transfer from one molecule to the next, and to the next, and so on.
What best describes a flight approaching the speed of sound?
If accelerating to the speed of sound, the subsonic.
What best describes a flight that is approaching speed of sound?
We call them ultra sonic planes. There is a sonic boom it is traveling when this speed.
What is the speed of sound flying?
Super sonic flight.
Why do you hear the sound of an approaching car before car reaches us?
Because the speed of sound travels at +- 1300 km/h and the car that is approaching isn't that fast. So u first hear the sound before the car reaches u.
Which passenger flight travels faster than sound?
The Concorde was one such flight which can make out a mac no of 1..thereby defeating the speed of sound..
The first flight faster than the speed of sound was called?
It was referred to as breaking the sound barrier.
Speed of sound is approx 740mph a police car with its siren sounding is approaching you at 80mph at what speed is the sound from the police siren approaching you?
The sound moves through the air at 740 mph, regardless of the speed of the source. The sound ofthe siren passes you at 740 mph.However, since the source is approaching you, more waves pass you each second than leavethe source each second. That's why the pitch of the sound from an approaching source soundshigher than its actual pitch.Also ... since the sound doesn't move away from the source any faster than 740 mph no matterhow fast the source is moving, that's why the pressure of the sound waves piles up in front ofthe source when the speed of the source approaches 740 mph, forming what's popularly calledthe "sound barrier".
What was the flight faster then speed called?
There was not a special name for the first flight that went faster than the speed of sound. However, when a plane does go faster than sound, it said to be traveling at supersonic speeds.
Describes a motion that is faster then the speed of sound?
The end of a whip, when cracked.
What is the speed and sound of air?
the speed of sound is describes how much distance is such a wave travels in a certain amount of time and the sound of air is wind noises.lol!! ~ ~
What most accurately describes the occurrence of a sonic boom?
A sonic boom occurs during the entire time the plane exceeds the speed of sound
Which of these best described a flight that is approaching the speed of light?
I honestly don't see anything in that list of choices that comes anywhere close to an adequate description.
