Question
If the length of a wire is cut to half then
(i) What would be the effect on its increase in length within the given weight?
(ii) What would be the effect on the maximum weight which it bears?
✓

Answer

It is clear from the increase in the length of the wire $l \propto L$ that if the length is half, the increase in length will be half. Maximum weight bear capacity does not depend on length.
Breaking stress $=\frac{\text { Maximum force }}{\text { Cross-sectional area }}$
Therefore, there is no effect on the maximum weight bear capacity.

 A copper calorimeter of mass 100 g contains a lump of ice at $4^{\circ} C$. When 520 calories of heat are given to the calorimeter and its contents, the temperature rises from $-4^{\circ} C$ to $-2^{\circ} C$. The addition of another 41540 calories of heat brings the temperature of the calorimeter and its contents to $2^{\circ} C$. Determine the specific heat capacity of copper and the mass of ice present in the calorimeter. Given: Latent heat of fusion of ice $=80 cal / g ^{-1}$ Specific heat capacity of ice $=0.5 cal / g ^{-1}\left({ }^{\circ} C \right)^{-1}$
