A tuning fork C procues 8 beats per second with another tuning f+ork D of frequency `340 Hz`. When the prongs of tuning fork C are filled a little, the number of beats produced per second decreases to 4 . Find the frequency of the tuning fork C before filing its prongs.

A tuning fork produces 8 beats per second with a tuning fork D of frequency 350 Hz .When the prongs of fork C are loaded with wax, the number of beats heard is 10 per second. Find the original frequency of fork C.

The prongs of the tuning fork are filled a little , the frequency of the tuning fork after filled

A sonometer wire resonates with a tuning fork. It itslength isincreased by 5%,10 beats are produced per second. The frequency of the tuning fork is.

A vibrating string of certain length l under a tension T resonates with a mode corresponding to the first overtone (third harmonic) of an air column of length 75cm inside a tube closed at one end. The string also generates 4 beats per second when excited along with a tuning fork of frequency n . Now when the tension of the string is slightly increased the number of beats reduces 2 per second. Assuming the velocity of sound in air to be 340 m//s , the frequency n of the tuning fork in Hz is

A stretched sonometer wire is in unison with a tuning fork.When the length is increased by 4 % , the number of beats heard per second is 6. Find the frequency of the fork.

A tuning fork gives 4 beats per second with a sonometer wire under tension of 26 N. If the tension on the wire is decreased to 24 N the number of beats remains the same before. What is the frequency of the tuning fork?

Two turning forks produce 4 beats per second when sounded together,The frequency of one of them is 200 Hz.When the other tunning fork is loaded with a little wax. The beats stop.The frequency of second funinf fork is

When a tuning fork A and B are sounded together,the number of beats heard are 4 per second.When tuning fork A is field,the number of beats heard per second with B is changed to 3.If the frequency of tuning fork B is 384 Hz,the original frequency of A is

A sonometer wire 100 cm long produces a resonance with a tuning fork . When its length is decreased by 10 cm, 8 beats per second are heard. Find the frequency of tuning fork.

The freuquency of tuning forks A and B are respectively 3% more and 2% less than the frequency of tuning fork C . When A and B are simultaneously excited, 5 beats per second are produced. Then the frequency of the tuning fork A (in Hz) Is
