QUESTIONS SOUND1. The sound produced by the loudspeaker does that the particles of the way (air) vibrate and this way to transport energy of a particle to other one.
2. The eardrum is a thin movie thatvibrates with certain frequency on having affected in this sonorous wave.
3.
4. The force of friction between the finger and the surface produces sonorous waves with everything the identifiableone, due to the liberation of calorific energy.
5. 33.25rpm - 70 rpm
On having duplicated the frequency, the tone of the sound becomes sharper, nevertheless, the extent is kept constant and thewave length diminishes
6. The characteristics of the sound are intensity, tone and stamp. The this intensity associated with the volume and the stamp to the source that produces it.
7. Theintensity has to see slowly with the volume of the issued sound, Of there that the tone does not have relation with this one.
8. The cardiac frequency defines as the times that late heart for unit oftime. Normally it expresses in pulsations per minute. It is a very important value in the sport since he says to us numerically, objectively and rapidly the adjustments to the exercise that they aretaking place in the sportsman.
9. Not, the energy is not created. Simply there is created a resonant effect that increases the extent of the sound, supporting other characteristics.
10. A)When the pipe is opened, the wave length is the fourth part of the length of the sound created across this one. B) When the pipe is closed, the wave length is the half of the length of the soundcreated across this one.
11. –Drum -Flute -Saxophone –Trumpet -Bagpipe
12. It does not receive it due to the fact that the sound issued by the engine directly on, because when...
