Radius of an air bubble at the bottom of the lake is `r` and it becomes `2 r` when the air bubbles rises to the top surface of the lake. If P cm of water be the atmospheric pressure, then the depth of the lake is

When an air bubble moves up from the bottom of a lake

An air bubble of diameter 1 mm is formed at the bottom of a lake and when it rises to the surface of the water, its diameter becomes 2 mm. If the atmospheric pressure is 760 cm of mercury, then find the depth of the lake. (Density of mercury = 13.6g*cm^(-3) )

An air bubble rises from the bottom of a lake of large depth. The rising speed of air bubble will

An air bubble rises from the bottom of a lake of large depth. The rising speed of air bubble will

When an air bubbles reaches the top of a lake from the bottom , its volume becomes 8 times . If the atmospheric pressure is 75 cms of Hg , the depth of lake is nearly

An air bubble released at the bottom of a lake, rises and on reaching the top, its radius found to be doubled. If the atmospheric pressure is equivalent to H metre of water column, find the depth of the lake (Assume that the temperature of water in the lake is uniform)
