A) \[\frac{1}{33}\]
B) \[\frac{1}{8}\]
C) \[\frac{1}{33}\times {{10}^{-4}}\]
D) All of it will melt
Correct Answer: A
Solution :
Suppose m¢ kg ice melts out of m kg then by using \[W=JQ\] Þ \[mgh=J({m}'L)\]. Hence fraction of ice melts \[=\frac{{{m}'}}{m}=\frac{gh}{JL}=\frac{9.8\times 1000}{4.18\times 80}=\frac{1}{33}\]You need to login to perform this action.
