A) \[4.0{}^\circ C\]
B) \[4.5{}^\circ C\]
C) \[5.0{}^\circ C\]
D) \[3{}^\circ C\]
E) \[5.5{}^\circ C\]
Correct Answer: C
Solution :
\[\alpha =\frac{\Delta L}{L\times \Delta t}\Rightarrow 12\times {{10}^{-6}}=\frac{6\times {{10}^{-5}}}{1\times \Delta t}\] \[\Rightarrow \] \[\Delta t=\frac{6\times {{10}^{-5}}}{12\times {{10}^{-6}}}=\frac{60}{12}=5{}^\circ C\]You need to login to perform this action.
