An average size of rain drop

Last Answer : I'm no expert but I guess it would vary because of the pollutants and other various materials floating in the air. For example, if you lived in San Francisco it might not take as along for the drop to fall ... clue if I'm right or wrong, but it sure sounds like I know what I'm talking about :)

A falling drop of rain water ac-quires the spherical shape due to – (1) Viscosity (2) Surface Tension (3) Atmospheric pressure (4) Gravitational force

Description : A falling drop of rain water ac-quires the spherical shape due to – (1) Viscosity (2) Surface Tension (3) Atmospheric pressure (4) Gravitational force

Last Answer : (2) Surface Tension Explanation: Raindrops start out as round high in the atmosphere as water collects on dust and smoke particles in clouds. But as raindrops fall, they lose their rounded ... the molecules stick together. The cause is the weak hydrogen bonds that occur between water molecules.
