How much work is required to form a bubble of 2 cm radius from the soap solution having surface tension 0.07N/m.

How much work is required to form a bubble of 2 cm radius from the soap solution having surface tension 0.07 N//m

How much amount of work is done in forming a soap bubble of radius r?

How much amount of work is done in forming a soap bubble of radius r?

The work done in blowing a soap bubble of radius R of the solution of surface tension T will be

A soap bubble of radius 'r' is blown up to form a bubble of radius 2r under isothemal conditions. If sigma be the surface tension of soap solution , the energy spent in doing so is

Amount of energy required to blow a bubble of radius 5 cm (surface tension of soap is 30xx10^(-2) N/m ) is

Two separate air bubbles (radii 2 cm and 4 cm ) formed of the same liquid (surface tension 0.07 N//m ) come together to form a double bubble. Find the radius in centimetre and the sense of curvature of the internal film surface common to both the bubbles.

The excess of pressure in a soap bubble of diameter 10 mm , when the surface tension is 0.04N//m is

Calculate the force required to take away a flat circular plate of radius 0.01 m from the surface of water. The surface tension of water is 0.075 N/m .
