Coefficient of linear expansion of brass and steel rods are alpha_(1) and alpha_(2) . Length of brass and steel rods are l_(1) and l_(2) respectively. If (l_(2) - l_(1)) is maintained same at all temperature, which one of the following relations holds good?

The coefficient of linear expansion of a rod is alpha and its length is L. The increase in temperature required to increase its legnth by 1% is

The coefficient of linear expansion varies linearly from alpha_(1) and alpha_(2) in a rod of length l . Find the increase in length when its temperature is increased by DeltaT .

Two rods AB and BC of equal cross-sectional area are joined together and clamped between two fixed supports as shown in the figure. For the rod AB and road BC lengths are l_(1) and l_(2) coefficient of linear expansion are alpha_(1) and alpha_(2) , young's modulus are Y_(1) and Y_(2) , densities are rho_(1) and rho_(2) respectively. Now the temperature of the compound rod is increased by theta . Assume of that there is no significant change in the lengths of rod due to heating. then the time taken by transverse wave pulse to travel from end A to other end C of the compound rod is directly proportional to

When solid is heated , its length changes according to the relation l=l_0(1+alphaDeltaT) , where l is the final length , l_0 is the initial length , DeltaT is the change in temperature , and alpha is the coefficient of linear is called super - facial expansion. the area changes according to the relation A=A_0(1+betaDeltaT) , where A is the tinal area , A_0 is the initial area, and beta is the coefficient of areal expansion. The coefficient of linear expansion of brass and steel are alpha_1 and alpha_2 If we take a brass rod of length I_1 and a steel rod of length I_2 at 0^@C , their difference in length remains the same at any temperature if

Two unifrom brass rod A and B of length l and 2l and radii 2r respectively are heated to the same temperature. The ratio of the increase in the volume of A to that of B is

Two rods, one of aluminium and other made of steel, having initial lenghts l_(1) and l_(2) are connected together to form a singel rod of length (l_(1)+l_(2)) . The coefficient of linear expansions for aluminium and steel are alpha_(a) and alpha_(s) respectively. If length of each rod increases by same amount when their tempertures are raised by t^(@)C , then find the ratio l_(1) (l_(1)+l_(2)) .
