Question:medium
A mercury drop of radius 1 cm is sprayed into 10⁶ drops of equal size. The energy expressed in joules is (surface tension of mercury is 460 × 10⁻3N/m):
A mercury drop of radius 1 cm is sprayed into 10⁶ drops of equal size. The energy expressed in joules is (surface tension of mercury is 460 × 10⁻3N/m):
Show Hint
When a liquid drop breaks into smaller drops, surface area increases and energy required is:
E = T (Af - Aᵢ)
Radius of each new drop is found using volume conservation.

Consider a water tank shown in the figure. It has one wall at \(x = L\) and can be taken to be very wide in the z direction. When filled with a liquid of surface tension \(S\) and density \( \rho \), the liquid surface makes angle \( \theta_0 \) (\( \theta_0 < < 1 \)) with the x-axis at \(x = L\). If \(y(x)\) is the height of the surface then the equation for \(y(x)\) is: (take \(g\) as the acceleration due to gravity)
