A tuning fork with a frequency of 528 hz is held above a resonance tube partially filled with water. A tuning fork, frequency 384 hz, produces resonance with a closed tube 20. Bigger is not always better and a larger pipe will actually slow this velocity thus restricting flow. The frequency of the piano's A is A) 440 Hz B) 444 Hz C) 880 Hz D) 436 Hz E) either 436 Hz or 444 Hz Ans: E. above or below a certain setpoint. The length of the air column can be varied by changing the water level. In an air column, the fork causes the loudest sounds at resonant lengths that are separated by 45. If it feeds the wrong data to the computer such as telling it the throttle is all the way to its highest end even though the vehicle is only running at normal speed, the computer may shut down the engine to protect it from over-revving.

If the speed of sound is equal to 340 m/s, the frequency of the tuning fork A) 2450 Hz B) 340 Hz C) 226 Hz D) 170 Hz. Find the spacing between the reso-nances when the air temperature is 20°C. When placed above the clip, they do nothing to effect jetting.
