If a number of little droplets of water of surface tension `sigma` all of the same radius r combine to form a single drop of radius R and the energy released in converted into kinetic energy find the velocity acquired by the bigger drop.

If a number of litle of droplets of water of surface tension S, all of the same radius r combine to from a single drop of radius R and the energy relased is converted into kinetic energy. Find the velocity acquired by the bigger drop. If the energy relased in converted inot heat, find the rise in temperature.

Let n number of little droplets of water of surface tension S (dyne/cm), all of the same radius r cm combine to from a single drop of radius R heat, while using cgs system of units answer the following questions. The energy released is

Let n number of little droplets of water of surface tension S (dyne/cm), all of the same radius r cm combine to from a single drop of radius R heat, while using cgs system of units answer the following questions. If the whole energy released is taken by water drop fromed, then rise in temperature in .^(@)C is

Let n number of little droplets of water of surface tension S dyn. Cm^-1 , all of the same radius r cm, combine to form a single drop of radius R cm. J is joule's mechanical equivalent of heat. While using CGS system of units answer the following questions. i. The energy released is

n droplets of equal size of radius r coalesce to form a bigger drop of radius R. The energy liberated is equal to
