A U-tube of uniform cross section (see figure) is partially filled with a liquid I. Another liquid II which does not mix with liquid I is poured into one side. It is found that the liquid levels of the two sides of the tube are the same, while the level of liquid I has risen by 2cm. If the specific gravity of liquid I is 1.1, the specific gravity of liquid II must be

A small spherical monoatomic ideal gas bubble (gamma= (5)/(3)) is trapped inside a liquid of density rho_(l) (see figure) . Assume that the bubble does not exchange any heat with the liquid. The bubble contains n moles of gas. The temperature of the gas when the bubble is at the bottom is T_(0) , the height of the liquid is H and the atmospheric pressure is P_(0) (Neglect surface tension). When the gas bubble is at a height y from the bottom , its temperature is :-

A ball of density rho_(0) falls from rest from a point P onto the surface of a liquid of density rho in the time T. It enters the liquid, stops, moves up, and returns to P in a total time 3 T. neglect viscosity, surface tension and splashing find the ratio of (rho)/(rho_(0))

A small spherical monoatomic ideal gas bubble (gamma=5//3) is trapped inside a liquid of density rho (see figure). Assume that the bubble does not exchange any heat with the liquid. The bubble contains n moles of gas. The temperature of the gas when the bubble is at the bottom is T_0 , the height of the liquid is H and the atmospheric pressure P_0 (Neglect surface tension). As the bubble moves upwards, besides the buoyancy force the following forces are acting on it

A liquid flows through a horizontal tube. The velocities of the liquid in the two sections, which have areas of cross section A_(1) and A_(2) are v_(1) and v_(2) respectively. The difference in the levels of the liquid in the two vertical tubes is h . Then

In a vertical U -tube containing a luquid, the two arms are maintained at different temperatures, t_(1) and t_(2) . The liquid coplumns in the two arms have heights l_(1) and l_(2) respectively. The coefficient of volume expansion of the liquid is equal to

A vertical U-tube contains a liquid. The total length of the liquid column inside the tube is 1 . When the liquid is in equilibrium, the liquid surface in one of the arms of the U-tube is pushed down slightly and released. The entire liquid column will undergo a periodic motion.

When a capillary tube is dipped in a liquid, the liquid rises to a height h in the tube. The free liquid surface inside the tube is hemispherical in shape. The tube is now pushed down so that the height of the tube outside the liquid is less than h . Then

A capillary of the shape as shown is dipped in a liquid. Contact angle between the liquid and the capillary is 0^@ and effect of liquid inside the mexiscus is to be neglected. T is surface tension of the liquid, r is radius of the meniscus, g is acceleration due to gravity and rho is density of the liquid then height h in equilibrium is:

An observer can see through a pin-hole the top end of a thin rod of height h, placed as shown in the figure. The beaker height is 3h and its radius h. When the beaker is filled with a liquid up to a height 2h, he can see the lower end of the rod. Then the refractive index of the liquid is
