Keeping the length of a wire unchanged, its diameter is doubled. Young's modulus for the material of the wire will

What is the SI unit of Young's modulus.

The radius of a copper wire is twice that of a steel wire. One end of the copper wire is joined with one end of the steel wire and the same tensile force is applied on them . If the length of the copper wire increases by 1% , what will be the percentage increase in the length of the steel wire? Given Young's modulus of steel is twice that of copper.

The unit of elastic modulus is

A wire, kept between two bridges 25 cm apart, is stretched through a linear expansion of 0.04 cm . Find the fundamental frequency of vibration of the wire. Given, the density and the Young's modulus of the material of the wire are 10 g*cm^(-3) and 9xx 10^(11) dyn * cm^(-2) , respectively.

A copper wire of negligible mass of length 1 m and cross sectional area 10^-6 m^2 is kept on a smooth horizontal table with one end fixed. A ball of mass 1 kg is attached to the other end. The wire and the ball are revolving with an angular velocity of 20 rad.s^-1 . IF the elongation in the length of the wire is 10^-3m , obtain the Young's modulus. IF on increasing the angular velocity to 100 rad .s^-1 the wire breaks down, obtain the breaking stress.
