| All stringed instruments rely on vibration to make sound. In an acoustic guitar, the strings are set vibrating by the fingers of the guitarist (on the nylon-stringed classical or flamenco instrument) or by a plectrum (on the metal-stringed instrument). As the strings are in contact with the bridge, they set the belly of the instrument vibrating, and it is this which produces the sound. Different thicknesses and types of wood produce sounds with different characteristics. The sound waves travel through the air to the ears of the listeners. The pitch of a note is determined by the frequency of vibration of ...(Answered by Rackbrane) | |

why is this so?? please answer!!? for my science project, i made a drum out of that powdered milk cans that are quite large, and so i need to explain this thing to my teacher, can you tell me why this is so?? When I keep the drum in my hand, it has more vibration and it creates more sound. Whereas when I keep the drum on the ground, it doesn’t make much sound because it doesn’t vibrate please answer!! ...

| You are on the right track by understanding that the difference lies in the vibrations. I would recommend looking into the following site to help you understand more about how sound travels and the things that affect sound. Hopefully, you will be able to offer a great explanation once you've explored and gained a deeper understanding of sound waves. http://library.thinkquest.org/19537/Main.html...(Answered by Mommy2006) | |

By what factor should the length of a simple pendulum be changed in order to triple the period of vibration? Please answer if you really do know.... ... (Asked by Pakistani16) |

| A. | |
| since for a pendulum, the equation for the period is: T = 2*pi*root(L/G) if you want the period to be tripled, that means period = 3*T, and you want it to be 3 times slower. Now we just solve for the new L For the left side to be multiplied by 3, L needs a coefficient of 9 (due to the sq root). Therefor the factor to change the length is 9...(Answered by Nes) | |

ALGEBRA HELP PLZ! (plz show work to help me understand!) THANK U!!!!!!!!!!? A.) car traveled from Detroit to Chicago at 75mph and returned on same route at 60 mph. If the time it takes to return to Detroit is one hr longer than the time it takes to get to chicago, how long did the total trip take? (hint: distance=rate*time. Total time is sum of time out and return trip. Distance on way out is same as distance on way back) B.) Airliner in S. America flew 630mi in 3hrs and 30min against the wind. The return trip only took 3hrs. Find speed of airplane in calm conditions and the speed of the ... (Asked by sunny_cherries2323) |

| A) x = time going to Chicago x+1 = time returning to Detroit 75 * x = distance to Chicago 60(x + 1) = distance returning Since the distances are equal 75x = 60(x + 1) 75x = 60x + 60 75x - 60x = 60 15x = 60 x = 4 hours x + 1 = 5 hours B) a = speed of airplane w = speed of wind 3.5(a - w) = 630 ...(Answered by Erwin B) | |

| Yes, the random movement causes the particles to move away from each other. It is a random process, but over time it will happen. Think of letting gas out of a balloon. Within a few minutes the gas will be evenly distributed around the room by the random vibrations of the particles....(Answered by scottie2h2004) | |

| A. | |
| The waves emitted by the truck as it goes by enters the medium of the air, causing you to hear it once the waves hit you. The higher the frequency (the closeness of the waves) the higher the pitch in the sound waves; also the higher the amplitude (the hight of the waves) the louder the sound waves are. The reason you feel it is because the same waves enter the medium of the ground and the vibrations meet your feet. (Mediums are the substance in which waves are traveling). Vibrations are merely waves traveling through a medium. Glad ...(Answered by Kind Answer Giver) | |
