When air of density `1.3kg//m^(3)` flows across the top of the tube shown in the accompanying figure, water rises in the tube to a height of `1.0cm`. What is the speed of air?

In a capillary tube of diameter 10^-3m , water rises to a height of 0.03 m. calculate the surface tension of water.

A vertical tube is made to stand in water so that the water level can be adjusted. Sound wave of frequency 320Hz are sent into the top of the tube. If standing waves are produced at two successive water levels of 20 cm and 73 cm , what is the speed of sound waves in the air in the tube (in m//s )

A point tube is mounted on an aeroplane wing to measure the speed of the plane. The tube contains alcohol and shows a level difference of 40 cm. What is the speed of the plane reative to air ? (sp. Gr. Of alcohol = 0.8 and density of air = 1 kg m^(-3) ).

A tuning fork of frequency 340 Hz is vibrated just above the tube of 120 cm height. Water is poured slowly in the tube. What is the minimum height of water necessary for the resonance? (speed of sound in the air = 340m/s)

A tuning fork of frequency 340 Hz is vibrated just above the tube of 120 cm height. Water is poured slowly in the tube. What is the minimum height of water necessary for the resonance? (speed of sound in the air = 340m/s)

An air column in a resonace tube of length 1.5 m resonates with a source of frequency 125 Hz, when the water level in it at a certain height from the bottom of the tube. What is the height of water level corresponding to the fundamental frequency ? ( Neglect the end correction and speed of sound in air is 330 m/s)

Water rises to a height of 10.3 cm in a capilaary of height 18 cm above the water level. If the tube is out at a height of 12 cm in the capillary tube

A capillary due sealed at the top has an internal radius of r = 0.05 cm . The tube is placed vertically in water, with its open end dipped in water. Find greatest interger corresponding to the length (in water) of such a tube be for the water in it to rise in these conditions to a height h = 1 cm ? The pressure The pressure of the air is P_(0) = 1 atm . = 7 cm of Hg , density of Hg = 13.6 //cm^(3) , g = 9.8 m//sec^(2) The surface tension of water is sigma = 70 "dyne"//"cm" . (assume temperature of air in the tube is constant)

At the middle of the mercury barometer tube there is a little column of air with the length l_(0) and there is vacuum at the top as shown. Under the normal atmospheric pressure and the temperature of 200 le,vom/ l_(0)=10cm . What will be the length of the air column if the temperature rises to 330 kelvin? (Neglict expansion of the tube)
