If the average terminal velocity of rain drop is 2 ms\(^{-1}\), then the energy transferred by rain to each square meter of the surface at a place which receives 100 cm of rain in a year is

A metal beam of length 1 m, breadth 2.5 cm and thickness 5 mm supported at its ends is loaded at its center by a weight of 25 N. The metal beam sags at the middle by an amount of (Young's modulus of the metal $= 2\times10^{11} Nm^{-2}$)

Petrol (density $= 750 \, kg m^{-3}$) and diesel (density $= 850 \, kg m^{-3}$) enter into two identical venturimeters each with a velocity $10 ms^{-1}$ as shown in the figure. If $\Delta h_1$ is the difference in heights of petrol in the two vertical tubes of venturimeter A and if $\Delta h_2$ is the difference in heights of diesel in the two vertical tubes of the venturimeter B, then $\Delta h_1 : \Delta h_2 =$

The pressure inside a mercury drop of diameter 2 mm is (Surface tension of mercury $= 0.5 Nm^{-1}$ and atmospheric pressure $= 10^5$ Pa)

A body is allowed to fall freely under gravity from a height of 15 m from the ground. At a point in its path, if the kinetic energy of the body is 200% more than its potential energy, then the velocity of the body at that point is (Acceleration due to gravity = 10 $ms^{-2}$)

The maximum length of water column that can stay without falling in a vertically held capillary tube of diameter 1mm and open at both the ends is (Acceleration due to gravity = 10 ms$^{-2}$ and surface tension of water = 0.07 Nm$^{-1}$)

A rain drop of diameter 1 mm falls with a terminal velocity of 0.7 ms$^{-1}$ in air. If the coefficient of viscosity of air is $2\times10^{-5}$ Pas, the viscous force on the rain drop is

If \(W_1\) is the work done in increasing the radius of a soap bubble from 'r' to '2r' and \(W_2\) is the work done in increasing the radius of the soap bubble from '2r' to '3r', then \(W_1: W_2 =\)
