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.
When you watch a plane flying high overhead why is it that the sound seems to come from behind the plane?
Because the speed at which you can see the plane is greater than the speed of sound.
What is the speed of a jet plane traveling at the speed of sound?
It depends on the aircraft's altitude. The speed of sound is decreasing as altitude increases, thus an airplane flying at the speed of sound at 1000 feet will be traveling as fast as 1200 kilometers per hour, while one flying at 30000 feet will be moving way slower, in the 800 kph range.
Who was famous for flying a plane?
Chuck Yeager broke the sound barrier for the first time.
How fast is a plane going if it is flying at Mach 3?
It is flying 3 times the speed of sound. Agreed. 2,300 mph at sea level
Whenever you watch a high flying aircraft overhead it seems that its sound comes from behind the craft why is that?
The sound takes time to travel from up in the air down to the ground. So, if the plane is directly overhead, the sound takes a little time to reach you, so that by the time you hear it, the plane has moved a bit. The sound is loudest when the plane is directly overhead, which is how we tend to judge where the sound is "coming from," so it appears to be coming from behind the plane. This is called the Doppler Affect.
If you a jet flying overhead where should you look to locate the plane?
Since the speed of sound is heard before the usually seeing things... you would behind the sound, suspecting this is what you were asking?
When a plane flying over us exceeds the speed of sound we hear an energy release called a sonic?
Those are ultra sonic planes. There is a sonic boom if it is traveling with sound speed.
Does fighters plane's sound break the glasses of window?
Yes- they can also knock over rickety old sheds if they are flying low enough.
What is the difference between hypersonic supersonic planes?
A supersonic plane is one that is flying faster than the speed of sound, or Mach 1. A hypersonic plane flies at a speed of Mach 5, so is much faster than a supersonic plane. Mach numbers are used for speeds greater than the speed of sound.
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
What is a sound wave increases the what of the sound increases?
Along with amplitude, being one of the key measurements of sound, the frequency of a sound wave affects the perceived pitch of the sound. As the frequency increases, the pitch becomes higher.
