A metallic wire is stretched in such a way that its new length becomes double its original length. How does its specific heat capacity change?

\( V_V, V_R, V_G \) are the velocities of violet, red, and green light respectively, in a glass prism. Which among the following is a correct relation?

Heat (in calorie) required to increase the temperature from \( 10^\circ C \) to \( 20^\circ C \) of 6 kg copper is the same as the heat (in calorie) required to increase the temperature from \( 20^\circ C \) to \( 100^\circ C \) of 3 kg lead. If the specific heat of copper is 0.09, then the specific heat of lead will be:
