A) \[{{10}^{o}}C\]
B) \[{{40}^{o}}C\]
C) \[50s\]
D) \[100s\]
Correct Answer: D
Solution :
\[e=BAD\,\,\sin \,37\times v\] \[e=4\times 0.3\,\sin \,37\times v\] \[l=\frac{4\times 0.3\times 0.60\times v}{12}\] \[2=\frac{4\times 0.3\times 0.6\times v}{12}\] \[v=\frac{24}{4\times 0.6\times 0.3}=\frac{100}{3}m/s\]You need to login to perform this action.
