Speed of Sound

False

The speed of sound in an ideal gas is not dependent on its density, but IS dependent on temperature. So, at a lower temperature, the speed of sound will decrease, making it easier to reach Mach 1.

Any change in motion (direction or speed) is a change in velocity.
Velocity is a vector quantity which means that it has a magnitude and a direction.

Moving faster than the speed of sound creates a shockwave. This shockwave is a wave of very high air pressure. When it hits glass it pushes on it and if the pressure of the shockwave is higher than the strength of the glass, the glass breaks.

I give the answer yes. Strings are made by metals. speed is high in metals.

its not

The Doppler effect occurs whether the sound source or the listener is moving. You wont notice the Doppler effect on a slow moving train because the radio wave is reflected, its frequency changes depending on the speed of the object.

The frequency range of a violin runs from about 400 Hz - 4,000 Hz. Assuming room temperature and atmospheric pressure, the speed of those sound waves will be 343 m/s. That corresponds to a wavelength range of 343/400 to 343/4,000 = .858 m - .0858 m, or roughly 3 ft. - 3 in. Compared to other musical instruments, that wavelength range is pretty average, albeit skewed slightly towards the shorter wavelength range.

No, the speed of sound (at sea level) is only about 0.213 mile per second.

The speed, and therefore also the wavelength (for sound of a given frequency), are affected by temperature.

yes it is changing. It's increasing with the temperature.

Bloodhound SSC has not made her first run yet. So far as I can tell, it has not been yet scheduled.

The speed will typically increase. It is hard to make a blanket statement though, because so much depends upon the type of medium being acted upon.

about 1,115 feet per second,

or 760 miles per hour,

or 2,044,380 furlongs per fortnight

'Radio' waves are physically and electrically identical to light waves except for their

frequency (wavelength), and they travel at the same speed as light does.

Between 3200 and 3600 m/s, the closer together the particles are in a substance are, the faster sound can travel through it. This is why these values are much higher than the 343 m/s, the speed of sound in air.

The airplane becomes more difficult to fly because there is more drag from air molecules

The speed of sound in gelatin depends on the gelatin concentration but it is approx 1520 metres/second.

Hey Ava==Take it to the garage and find out what is happening. goodluckJoe

Chuck Yeager had been an Army Air Corps "Ace" fighter pilot, including becoming an "ace in a day" by destroying five German aircraft during WWII- in one day! One of his "kills" was one of the first German ME-262 jet fighters.

Because Yeager had been an evadee in World War II, he got his pick of bases in the US after the war. He chose the closest to his home - Wright Patterson in Ohio, not far from West Virginia. That was where flight test was in 1945.

Chuck was a maintenance officer there, and due to his background helping his father drill gas wells, he understood the systems in the X-1. As a maintenance officer, he flew more airplanes than anyone else. He also flew in air shows. Col. Boyd said that he was the best.

General Yeager, born February 13, 1923, lives with his second wife (his first died in 1990) and continues to fly jets, P-51s, and light planes.

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
