A steel wire of length 2 m and cross sectional area 2 mm^2 is fixed at one end and stretched by suspending a block of mass 2 kg on the surface of the moon. If the Young's modulus of steel is 2 xx 10^11 N m^(-2) find the increase in the length of the steel wire. (g on the moon = 1/6 of the g on the earth)

A metal rod of length 10 cm and area of cross section 2.8 times 10^-4 m^2 is covered with a non-conducting substance. One end of it is maintained at 80^@C , while the other end is put in ice at 0^@C . It is found that 20 gm of ice melts of 5 min. The thermal conductivity of the metal in Js^-1 m^-1 K^-1 is (Latent heat of ice is 80 cal g^-1 ).

A wire of length 50 cm and weighing 10 gm is attached to a spring at one end and to a fixed wall at the other end. The spring has a spring constant of 50 N/m and is stretched by 1 cm. If a wave pulse is produced on the string near the wall, then how much time will it take to reach the spring?

A steet wire of length 4.7 m and cross - sectional area 3.0xx10^(-5)m^(2) stretches by the same amount as a copper wire of length 3.5 m and cross- sectional area of 4.0xx10^(-5)m^(2) under a given load. What is the ratio of the Young's modulus of steel to that of copper ?
