What happens to air as sound travels through it?
Sound is transmitted from a source to the surrounding air particles, which vibrate or collide and pass the sound energy along to our ears. Without any particles to vibrate we wouldn't hear the sound.
How can you change the wavelength of a wave in a rope without changing the amplitude?
By making it vibrate faster or slower.
What was your average spped for waves with 1-hz frequency?
The speed of a wave does not depend on its frequency. We would only need to know what kind of a wave it was ... whether sound, earthquake, ocean, electromagnetic, etc. ... and what substance it was moving through at the time, and we could either calculate or look up its speed, without ever knowing its frequency.
How is sound or noise measured?
How Sound can be measuredSound is basically a vibration that touches your ear and makes your ear vibrate so you can hear the sound. Something like a musical instrument or someone tapping their knees makes the air around the object vibrate and the air around the object that is now vibrating keeps going until it runs out of energy, if someone's ear where in the way of the vibration it would vibrate the persons ear so that the person could hear the sound. Sound is measured in frequency the quicker the frequency the higher the note or noise.Sound can be measured in many ways such as decibels (unit of sound) there is a special machine which you can by that measures how many decibels something makes. A pin makes 10 decibels where as a loud persons personal stereo can make up to 80 decibel's. Frequency is also a good way of measuring sound because even without hearing the sound you can know whether or not it is a high or low note. If the frequency is very fast then there is a high note but if the frequency is very slow then there is a low note.
How does sound travel through oxygen?
Sound is a mechanical wave that can best be described as a 'vibrational' form of energy. It propagates throughout a space by vibrational motions of molecules. In other words, it does not technically travel through oxygen molecules but the sound energy makes the molecules vibrate. As the molecules vibrate, the energy is passed on to other molecules by collision and therefore the energy is transferred on and on. Without a medium to travel through, sound energy cannot propagate or travel. In other words, if a bomb goes off in the middle of space or a vacuum, you will not be able to hear the explosion no matter how close you are to the explosion.
How do you convert tones to cubic meter natural gas?
The tone, or frequency of sound depends on the density of the medium that it is travelling through. Without information about the composition of the natural gas, it temperature and pressure, it is not possible to work out its density and so the tone of sounds propagating through it.

Is it possible to make a noise with your vocal chords without breathing?
No, that is not possible. Your vocal chords vibrate when air is forced through them so it would not be possible to use them without breathing.
How does a guitar vibrate without touching it?
it doesn't

Can an object vibrate without having pitch?
Yes
What is the purpose of wrapped strings in some musical instruments?
The purpose of wrapping stringed instruments comes from the physical properties of waves traveling through a string. Two formulas can be employed to briefly describe waves and the wrapping of strings.(wave speed) =sqrt (frequency / mass per unit length)and(wave speed = wavelength * frequency)If you notice a guitar for example, the lower base note strings are wrapped and the higher frequency strings are not wrapped. In order to get the lower base note string to vibrate at the lower frequency you must increase the mass per unit length of the string. However, steel being the material it is does not remain flexible when you increase its thickness per unit length (mass per unit length). So the steel is wrapped so that you can increase the thickness of the string without increasing the rigidity of the string. As a result, it can vibrate freely and be a welcoming medium to sustain your desired bass frequency.-G

How do you control rpm of single phase motor without using variable frequency drive?
By changing the voltage through a potentiometer ( eg fan regulator )
How can you change the wavelength of a wave in a rope without changing the amplitude?
By making it vibrate faster or slower.
How is the universe noisey without air?
Sound waves cannot travel through space and be heard by humans. There is no air wich means the air cannot vibrate wich means our ears cannot pick it up.
What is coarse frequency offset?
the frequency difference between the transmitter and the receiver without any noise or distortion
