A) \[{{80}^{o}}C\]
B) \[{{60}^{o}}C\]
C) \[{{160}^{o}}C\]
D) \[{{40}^{o}}C\]
E) \[{{120}^{o}}C\]
Correct Answer: A
Solution :
Hence \[=\frac{1}{2}\times \frac{1}{2}m{{v}^{2}}=\frac{1}{4}m\times 4\times {{10}^{4}}\] \[=125\times \Delta T\times m\] \[\Delta T=4\times \frac{{{10}^{4}}}{500}={{80}^{o}}C\]You need to login to perform this action.
