An open U -tube of uniform cross-section contains mercury. When 27.2 cm of water is poured into one limb of the tube, (a) how high does the mercury rise in the limb from its initial level ? (b) what is the difference in levels of liquids of the two sides ? (`rho_(w) =1` and `rho_(Hg) =13. 6` units)

An open U-tube contains mercury. When 11.2 cm of water is poured into one of the arms of the tube, how high does the mercury rise in the other arm from its initial level ?

A vertical uniform U tube open at both ends contains mercury. Water is poured in one limb until the level of mercury is depressed 2cm in that limb. What is the length of water column when this happens.

A vertical U-tube contains a liquid of density rho and surface tension T. if the radius of the meniscus of liquid in the limbs of the U-tube are R_(1) and R_(2) find the difference in the liquid column in the limbs.

A vertical U-tube of uniform cross-section contains water jn both the arms. A 10 cm glycerine column (R.D. = 1.2) is added to one of the limbs. The level difference between the two free surfaces in the two limbs wiil be

A vertical U-tube of uniform cross-section contains water upto a height of 30 cm. show that if the water in one limb is depressed and then released, its up and down motion in the two limbs of the tube is simple harmonic and calculate its time-period.

A thread of mercury of 10.2 g is in a tube of uniform cross-section 0.1cm^2 . Calculate the length of the thread. The density of mercury is 13.6(g)/(cm^3) .

A U - tube of uniform cross section contains mercury upto a height h in either limb. The mercury in one limbe is depressed a little and then relased. Obtain an expression for time period (T) of oscillation, assuming that T depends on h, rho and g, where rho is density of mercury.

Fig, shows a U-tube of uniform cross-sectional area A accelerated with acceleration a as shown. If d is the seperation between the limbs. Then the difference in the levels of the liquid in the U-tube is

A vertical U tube of uniform cross section contains mercury in both of its arms. A glycerine (d=1.3g//cm^(3)) column of length 10 cm is introduced into one of the arms. Oil of density 0.8g//cm^(3) is poured in the other arm until the upper surfaces of the oil and glycerine are in the same horizontal level. Find the length of oil column. Densit of mercury is 13.6g//cm^(3) .
