A wire is in unison with a fork of frequency `250Hz`, when stretched by a weight hanging vertically.On immersing the weight in water , the wire produces ten beats per second with the same fork.Calculate density of material of weight , if density of water is one g per cc.

A sonometer wire is in unison with a tuning fork when it is stretched by a weight of specific gravity 9. When the weight is completely immersed in water, 10 beats per second are heard .Calculate the frequency of the tuning 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 sonometer wire is in unison with a tuning fork.When its lengths increases by 4%, it gives 8 beats per secon with the same the fork. The frequency of the fork is

A sonometer wire produces 2 beats per second with a tuning fork , when the length of the wire is either 102 cm or 104 cm. The frequency of the tuning fork is

A tuning fork and a sonometer wire were sounded together and produced 4 beats per second when the length of sonometer wire is 95 cm or 100 cm. The frequency of the tuning fork is

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.

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 of known frequency 256 Hz makes 5 beats per second with the vibrating string of a piano.The beat frequency decreases to 2 beats per second when the tension in the piano string is slightly increased.The frequency of the piano string before increasing the tension was

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 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.
