If each drop of water has a radius of 1 mm, find the number of drops that may be filled in a cubical container of side 1 cm.

A cylindrical jar, whose base has a radius of 15 cm, is filled with water upto a height of 20 cm. A solid iron spherical ball of radius 10 cm is dropped in the jar to submerge completely in water. Find the increase in the level of water (in cm).

Mearbles of diameter 1.4 cm are dropped into a cylindrical beaker of diameter 7 cm, containing some water. Find the number of marbles that should be dropped into the beaker so that the water level rises by 5.6 cm.

Eight equal drops of water each of radius r=2 mm are falling through air with a teminaln velocity of 16 cm/s . The eight drops combine to be from a big drop. Calculate the terminal velocit of big drop.

125 drops of water each of radius 2 mm and carrying charge of 1 nC are made to form a bigger drop. Find the capacitance and potential of the bigger drop.

Marbles of diameter 1.4cm are dropped into a cylindrical beaker of diameter 7cm containing some water.Find the number of marbles that should be dropped into the beaker,so that the water level rises by 5.6cm.

When a big drop of water is formed from n small drops of water, the energy oss is 3E, where, E is the energy of the bigger drop. If R is the radius of the bigger drop and r is the radius of the smaller drop then number of smaller drops (n) is?

If a drop of water of radius 0.1 cm is broken up into a million droplets all of the same size , then the energy expended in the process will be

Eight drops of water, each of radius 2mm are falling through air at a terminal velcity of 8cms^-1 . If they coalesce to form a single drop, then the terminal velocity of combined drop will be

Eight equal drops of water each of radius r=2mm are falling through air with a terminal velocity of 16(cm)/(s) . The eight drops combine to form a big drop. Calculate the terminal velocity of big drop.
