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?

Water rises in a capillary tube of diameter 0.2xx10^(2)m upto a height of 1.5 cm. The surface tension of water is-

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 )

Water rises to a height of 16.3cm in a capillary of height 18cm above the water level. If the tube is cut at a height of 12cm

A light cylindrical tube 'T' of length l and radius 'r' containing air is inverted in water (density d). One end of the tube is open and the other is closed A block 'B' of density 2d is kept on the tube as shown in the figure. The tube stays in equilibrium in the position shown. (Assume the atmosphere pressure is to be P_(0) ) Assume that density of air is very small than density of block and water. Pick up the correct statement (s)

A light cylinderical tube of length L=1.5m and radius v=(1)/sqrt(pi)m is open at one end. The tube containing air is inverted and pushed inside water as shown in figure. A block made of material of relative density 2 haas been placed on the flat upper surface of the tube and the whole system is in equilibrium Neglect the weight of air inside the tube and find the volume of block placed on the tube.

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)

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
