A wire loaded by a weight of density `7.6 g cm^(-3)` is found to measure `90 cm`. On immersing the weight in water, the length decreases by `0.18 cm`. Find the original length of wire.

A wire loaded by a weight of density 7.6 g cm^-3 is found to be of length 90 cm. On immersing the weight in water, the length decreased by 0.18 cm. Find the original length of the wire.

A wire loaded by a weight of density 7.8 g//c c is found to be of length 100cm. On immersing the weight in water. The length decrease by 0.20 cm find the original length of the wire.

A wire loaded by a weight of density 7.8 g//c c is found to be of length 100 cm. On immersing the weight in water. The length decrease by 0.20 cm find the original length of the wire.

A wire is loaded by a weight of density 9g//cm^(3) and stretched to a length of 98 cm. On immersing the weight in water the length shortens by 2.5 mm. Then the original length of the wire will be [rho_(w)=1 gm//cm^(3)]

A tungsten wire of length 20cm is stretched by 0.1cm. Find the strain on the wire.

The diameter of a copper sphere is 6 cm. It is beaten and drawn into a wire of diameter 0.2 cm. Find the length of wire.

A 50 cm long wire is in unison with a tuning fork of frequency 256, when stretched by a load of density 9 g cm^(-3) hanging vertically . The load is then immersed in water.By how much the length of the wire be reduced to bring it again in unison with the same tuning fork ?
