Two metaliic strips of different metals are riveted together to form a composite metallic strip of thickness 0.1 cm. If the strip is heated to 100^(@)C , what will be the radius of curvature of the strip? Given, the values of alpha of the two metals are 18 times 10^(-6@)C^(-1) " and " 12 times 10^(-6@)C^(-1) .

A bimetalic strip is made of two strips A and B, having co-efficeint of linear expansion as alpha_(A) and alpha_(B) . If alpha_(A) gt alpha_(B) which of the following describes the behavior fo the metallic strip when heated?

(A) Among 15^(th) group elements nitrogen has the least B.P where as Bi has the high B.P than N. (R ) Nitrogen is a non metal where as Bi is a metal

A : The bond angle of NH_3 is greater than BiH_(3) . R : 'Bi' is metal while N is non - metal .

A : The bond angle of NH_3 is greater than BiH_(3) . R : 'Bi' is metal while N is non - metal .

A bimetallic strip is formed out of two identical strips, one of copper and the other of brass. The coefficients of linear expansion of the two metals are alpha_(c) and alpha_(B) . On heating, the temperature of strip increases by DeltaT and the strip bends to form an arc of radius R. Then R is proportional to
