When an air bubble rises from the bottom of a lake to the surface, its radius, is doubled. Atmospheric pressure is equal' to the pressure of a water column of height it. Depth of the lake is-

When an air bubble rises from the bottom of a lake to the upper surface , its diameter increases from 1mm to 2mm. IF the atmospheric pressure is 76 cmHg,calculate the depth of the lake. Density of mercury is 13.6g.cm^-3 .

An air bubble starts rising from the bottom of a lake. Its diameter is 3.6 mm at the bottom and 4mm at the surface. The depth of the lake is 250 cm and the temperature at the surface is 40^@C . The atmospheric pressure is 76 cm of Hg and g=980 cm.s^-2 . What is the pressure at the bottom of the lake?

An air bubble starts rising from the bottom of a lake. Its diameter is 3.6 mm at the bottom and 4mm at the surface. The depth of the lake is 250 cm and the temperature at the surface is 40^@C . The atmospheric pressure is 76 cm of Hg and g=980 cm.s^-2 . What is the temperature at the bottom of the 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) )
