A wire of length 1m and area of cross section `4 xx 10^(-8) m^(2)` increases in length by 0.2 cm when a force of 16 N is applied. Value of Y for the material of the wire will be

A wire of area of cross-section 10^(-6) m^(2) is increased in length by 0.1 %. The tension produced is 1000 N. The Young's modulus of wire is

The length of a wire is 1.0 m and the area of cross-section is 1.0 xx 10^(-2) cm^(2) . If the work done for increase in length by 0.2 cm is 0.4 joule, then Young's modulus of the material of the wire is

A wire of length15m (meter) and uniform area of cross section 6.0 xx 10^-7 m^2 has resistance of 5.0 Omega (ohm). What is the resistivity of the material of the wire ?

A uniform wire of length 6m and a cross-sectional area 1.2 cm^(2) is stretched by a force of 600N . If the Young's modulus of the material of the wire 20xx 10^(10) Nm^(-2) , calculate (i) stress (ii) strain and (iii) increase in length of the wire.

Work done in stretching a wire of length 1 m and of cross-sectional area 1 mm^(2) through 2 mm if Young's modulus of the material of the wire is 2 xx 10 ^(11) N//m^(2) is .......

A force of 200 N is applied at one end of a wire of length 2m and having area of cross-section 10^(-2) cm^(2) . The other end of the wire is rigidly fixed. If coefficient of linear expansion of the wire alpha=8xx10^(-6)//.^(@)C and Young's modulus Y=2.2xx10^(11)N//m^(2) and its temperature is increased by 5^(@)C , then the increase in the tension of the wire will be
