Freezing compartment of a refrigerator is at $0^{\circ} C$ and room temperature is $27.3^{\circ} C$. Work done by the refrigerator to freeze $1\, g$ of water at $0^{\circ} C$ is $\left(L_{ ice }=80\, cal\, g ^{-1}\right)$

Water stands upto height $h$ behind the dam as shown in the figure. The front view of the dam gate is also shown in the adjoining figure. Density of water is $\rho$ and acceleration due to gravity is $g$. If atmospheric pressure force is also considered, then the point of application of total force acting on the dam due to water above $O$ is

A TV transmitter has a range of $50\, km$. The height of the TV transmitter is (Radius of the earth, $R_{e}=6 \cdot 4 \times 10^{6}\, m$ )
