The variation of length of two metal rods A and B with change in temperature are shown in fig. The coefficients of linear expansion alpha_(A) for the metalA and the temperature T will be (Given alpha_(a) = 9 xx 10^(-6) //°C )

The variation of length of two metal rods A and B with change in tempe

1.	The variation of length of two metal rods A and B with change in temperature are shown in fig. The coefficients of linear expansion alpha_(A) for the metalA and the temperature T will be (Given alpha_(a) = 9 xx 10^(-6) //°C )
Answer» `alpha_(A) =3xx 10^(-6) //°C, 500^(@) C` `alpha_(A) = 3 xx 10^(-6)//""^(@) C, 222.22^(@) C` `alpha_(A) = 27 xx 10^(-6) //""^(@) C` `alpha_(A) = 27 xx 10^(-6)//""^(@) C, 222.22^(@) C` ANSWER :D
