The surface of water in a water tank of cross-section area \(750\) cm\(^2\) on the top of a house is \(h\) m above the tap level. The speed of water coming out through the tap of cross-section area \(500\) mm\(^2\) is \(30\) cm/s. At that instant, \(dh/dt\) is \(y\times 10^{-3}\) m/s. The value of \(y\) will be

A horizontal pipeline carries water in streamline flow. At $A_1 = 10$ cm$^2$, $v_1 = 1$ m/s and $P_1 = 2000$ Pa. The pressure at $A_2 = 5$ cm$^2$ is \dots [$\rho = 1000$ kg/m$^3$]

A body of density $\rho$ is dropped from (at rest) height $h$ into a lake of density $\delta$ ($\delta > \rho$). The maximum depth to which the body sinks before returning to float on the surface is [Neglect all dissipative forces]
