An air bubble rises to the surface of water from a depth of `2.5m`. The temperature on the surface of water is `40^(0)C` .If the radii of the bubble are `1.8mm` and `2mm` at that depth and on the surface respectively, what is temperature at the depth(nearly)

A swimmer goes from the surface of water to a depth of 20m the change in the pressure on his body is nearly

A point source is placed at a depth h below the surface of water (refractive index = mu ). The medium above the surface of water is air from water.

An air bubble is formed at depth h below the surface of water. The pressure inside the bubble is- ( P_(0)= atmospheric pressure, r = radius of bubble)

A small air bubble of radius 0.1 mm is situated at a depth of 10 m below the free surface of water .The external pressure on the bubble will be

An air bubble rises from the bottom to the surface of lake and it is found that its diameter is duubled. If the height of water barometer is 11m , the depth of the lake in maters is

When an air bubble rise from the bottom of a deep lake to a point just below the water surface, the pressure of air inside the bubble

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

When an air bubble of radius 'r' rises from the bottom to the surface of a lake, its radius becomes 5r//4 (the pressure of the atmosphere is equal to the 10 m height of water column). If the temperature is constant and the surface tension is neglected, the depth of the lake is

An air bubble is lying just below the surface of water. The surface tension of water is 70xx10^(-3)Nm^(-1) and atmospheric pressure is 1.013xx10^(5)Nm^(-2) . If the radius of bubble is 1mm, then the pressure inside the bubble will be-
