A sonometer wire is stretched by tension of 40 N. It vibrates in unison with a tuning fork of frequewncy `384Hz`. How many numbers of beats get produced in two seconds if the tension in the wire is decreased by `1.24 N`?

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 weight is attached to the free end of a sonometer wire. It gives resonance at length of 40 cm, when it is vibrating in unison with tuning fork of frequency 512 Hz. The weight is then immersed wholly in water, the resonating length is reduced to 30 cm. The relative density of the fluid in which weight is immersed is

A length of sonometer wire under constant tension when sounded with a tuning fork of higher frequency 271 Hz produced 5 beats per second. If the length of the wire is reduced by 5%, find the new frequency of the wire.

A sonometer wire under certain tension is in unison with a tuning fork. When only the tension in the wire is increased by 2 % , 3 beats per second are produces.Find the frequency of fork.

A metal wire of diameter 1 mm is held on two knife edges separated by a distance of 50 cm. The tension in the wire is 100 N. The wire vibrates with its fundamental frequency and a vibrating tuning fork together produce 5 beat/s . The tension in the wire is then reduced to 81 N. When the two are excited , beats are heard at the same rate, then the frequency of the fork will be

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 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.

Two identical wires have the same fundamental frequency of 400 Hz . when kept under the same tension. If the tension in one wire is increased by 2% the number of beats produced will be

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
