sound is created because of vibrations in air.
i.e The change of vibrations in air creates sound.
In vacuum there is no air. So it is not possible to create sound in vaccum.
Sound does move through space. It doesn't move though empty space, i.e. a vaccuum. In outer space there is a vaccuum (though not necessarily a perfect vaccuum).Sound is caused by vibrations in a medium such as air (or water or wood). These vibrations compress and rarefy the medium. The vibrations move through the medium as waves.In a vaccuum, there is no medium thus there is no sound.
No medium to carry the sound energy.
Sound waves.
Speed of sound is maximum in STeel or solid.. if we compare the speed of sound in different mediums like vaccuum,water,solid..we will find it decreases with maximum in soild then liquid and then vaccuum
it takes the rubbish through to the vaccuum cleaners inner part where the rubbish is kept
Sounds like the vaccuum modulator might have gotten disconnected. Pass side of the car, side of the trans. A vaccuum diaphram, with a vaccuum hose connected, that runs up to the motor.
simple sound needs propogation medium but in vaccuum their is no medium to prpogate so acts as to stop noise in bell jar
Vaccuum it out
Yes. Refer to stars - space is a vaccuum (though not a perfect vaccuum) and because light can travel through a vaccuum, we have day and night here on Earth. We can even see light from other stars light years away.
Vaccuum leak. Replace all vaccuum lines that look cracked, should fix the problem.
Where is the humming located front, rear? Could be a vaccuum leak if high pitched, wheel bearings, improper brake installation. More info needed.
pull out a vaccuum gauge install on vaccuum port of carburetor start vehicle use adjustment screws to pull the most vaccuum as possible on each port,repeat process on second port once adjusted press throttle to around 2000 r.p.m.'s to determine where vaccuum gauge needle is operating at.
