A) same as that in Y
B) half of that in Y
C) twice of that in Y
D) Eight times of that in Y
Correct Answer: D
Solution :
\[P=\frac{1}{3}\,\frac{mn{{u}^{2}}}{\upsilon }\] \[\frac{{{P}_{s}}}{{{P}_{y}}}=\frac{{{n}_{s}}{{u}_{x}}{{u}_{y}}}{{{n}_{y}}{{u}_{u}}{{\upsilon }_{x}}}=\frac{\left( {}^{{{N}_{0}}}/{}_{1000} \right)}{\left( {}^{{{N}_{0}}}/{}_{2000} \right)}\times 2\times \frac{2}{1}=8\]You need to login to perform this action.
