A) \[\frac{9}{4}\]
B) \[\frac{3}{2}\]
C) \[\frac{5}{3}\]
D) \[\frac{27}{8}\]
Correct Answer: D
Solution :
[d] \[\Delta Q=ms\Delta T\] |
\[\Delta Q=\frac{4}{3}\pi {{r}^{3}}\rho s\Delta T\] |
\[\frac{\Delta {{Q}_{1}}}{\Delta {{Q}_{2}}}={{\left( \frac{{{r}_{1}}}{{{r}_{2}}} \right)}^{3}}\] |
\[={{(1.5)}^{3}}\] |
\[=\frac{27}{8}\] |
