1.	The two ends of a wire are rigidly fixed . If the temperature is decreased by 10^(@) C , find the tension in the string from the given quantities : cross sectional area of the wire= 0 . 01 cm^(2), coefficient of linear expansion of the material of the wire= 16 xx 10^(6_(@)) C^(-1)and Young's modulus= 20 xx 10^(11) dyn * cm^(-2) .If the frequency of transverse wave produced in the wire is twiece the previous value, what was the initial tension in the wire ?
