143221 A motor engine pumps $1800 \mathrm{~L}$ of water per minute from a well of depth $30 \mathrm{~m}$ and allows to pass through a pipe of cross-sectional area 30 $\mathrm{cm}^{2}$. Then the power of the engine is (Acceleration due to gravity, $g=10 \mathrm{~ms}^{-2}$ )

143222 A cylindrical vessel filled with water is released on an inclined surface of angle $\theta$ as shown in figure. The friction coefficient of surface with vessel is $\mu( \lt \tan \theta)$. Then the contact angle made by the surface of water with the incline will be-
