A) 2.35
B) 3.0
C) 1.50
D) 1.70
Correct Answer: D
Solution :
[d] Power \[\vec{F}.\vec{V} = PA\vec{V} =\rho ghAV\] \[\left[ \because \frac{F}{A}and\,P=\rho gh \right]\] \[= 13.6\times 1{{0}^{3}}\times 10\times 150\times 1{{0}^{-3}}\times 0.5\times 1{{0}^{-3}}/60\]\[=\frac{102}{60}=1.70\operatorname{watt}\]You need to login to perform this action.
