1. A source 2. Elastic medium (air) 3. A receiver
First, something must vibrate. Second, you need something through which the vibrations, or sound waves, can travel. Third, these traveling vibrations must be received somehow.
A transmitter, a medium thru which to travel, and a receiver.
1.A Source:A body having particles that can vibrate.
2.A Medium:An elastic medium for the propagation of sound.
3.A receiver.
Sound cannot be transmitted in a vacuum.
Medium and electricity
the speed of sound depends on the material it is passing through and the tempature.colder tempatures will slow the transmission of sound whereas heat will speed it up...
Microphone is a device which coverts the longitudinal sound vibrations falling on it into electrical signals.
One of the cons of sound energy is it is a disturbance to schools, sleep and silence - the three S's. One of the pros of sound energy is being able to hear it as it is used in healing and meditation.
The sound waves only travel along one dimension whereas the water travels in three dimensions.
No matter what the mass is, there are two conditions for equilibrium:The sum of forces on an object must be zero.The sum of torques on an object must be zero.For actual calculations, each of these conditions usually translates to three separate equations.
There are three components in the production of sound. The first thing you need is a physical object that is vibrating, because vibrations create sound. The next thing you need is a medium to carry out the vibrations. The last necessary piece in the production of sound is an ear to hear the sound and turn it into something meaningful. These three things are as simple as a person playing an instrument to a crowd.

The three conditions necessary for causation between variables are covariance (relationship between variables), temporal precedence (the cause must precede the effect in time), and elimination of plausible alternative explanations (other possible causes are ruled out).
For demand to exist you have to want a good. You have to be able to afford the good. And you have to have a definite plan to buy the good.
when necessary, these bones can reduce sound intensity to the inner ear
It is just left of Sound Stage 4, which is down in the lower right corner of the studio lot. From Sound Stage 1, Sound Stage 2 is 2 blocks to the right. From Sound Stage 1, Sound Stage 3 is three blocks down. From Sound Stage 1, Sound Stage 4 is 4 blocks down and 3 blocks right. From Sound Stage 1, Post Production is 4 blocks down and 2 blocks right.
A beneficial mutation leading to variability in a population and the heritability of those beneficial traits.
The Production Budget for Three Kings was $48,000,000.
The Production Budget for Three to Tango was $20,000,000.
In chess, in order for a check to be a checkmate, there are three specific conditions: 1) The king must not be able to move out of check. 2) The attacking piece must not be capture-able. 3) No pieces must be able to block the check.
