Number of beats means the difference between frequencies of the two sources. Here frequency of tunning fork is 440 Hz and on decreasing the frequency of string, number of beats decreases, so it is confirmed that frequency of string was more than that of tunning fork, so it was 444 Hz. Option (c).

Question 5 1 pts Tuning fork A has a frequency of 440 Hz. When A and a second tuning fork B are struck simultaneously, four beats per second are heard. When a small mass is added to one of the tines of B, the two forks struck simultaneously produce two beats per second. The original frequency of tuning fork B was 436 Hz. 432 Hz. 444 Hz. 448 Hz 438 Hz.

A flutist assembles her flute in a room where the speed of sound is 342 m/s . When she plays the note A, it is in perfect tune with a 440 Hz tuning fork. After a few minutes, the air inside her flute has warmed to where the speed of sound is 343 m/s. How many beats per second will she hear if she now plays the note A as the tuning fork is sounded? How far does she need...

A musician in a concert hall is tuning her wind instrument. When she plays a short note she hears the echo of the note return from the opposite side of the 50.0 meter long auditorium 0.294 seconds later. Model the instrument as a tube closed at one end, if the instrument is properly tuned the note of the musician played would have a frequency of 233.082 Hz, but instead has a frequency of 226.513 Hz. This note is the first...
