A) \[5.0\times {{10}^{3}}Ns\]
B) \[3.5\times {{10}^{6}}Ns\]
C) \[1.4\times {{10}^{6}}Ns\]
D) \[6.3\times {{10}^{4}}Ns\]
Correct Answer: A
Solution :
\[Pressure=\frac{I}{C}\] \[Force=Pressure\times Area=\frac{I}{C}.Area\] Momentum transferred = Force .\[\Delta t\] \[=\frac{I}{C}.Area.\Delta t\] \[=\frac{25\times {{10}^{4}}}{3\times {{10}^{8}}}\times 25\times {{10}^{-4}}\times 40\times 60\] \[=5\times {{10}^{-3}}N-s\]You need to login to perform this action.
