An air bubble of diameter 1 xx 10^(-3)m rises in water. Calculate the terminal velocity of the bubble.

A soap bubble of radius R = 3 cm and thickness t = 10^(-2) mm is charged to a potential of V = 0.3 volt. The bubble burst and falls as a spherical drop. Determine the potential of the drop

Excess pressure inside one soap bubble is four times that of other. Then the ratio of volume of first bubble to second one is
