KUNDT'S TUBE

Kundts Tube||Beats

In a Kundt's dust tube experiment a brass rod was found to resonate with 10 cm of a sonometre wire stretched by 6 kg. One hundred centimetre of the wire was found to weight 653 mg. This rod produced nodal heaps 12 cm apart in air. Calculate the velocity of sound in air.

Tube A +HNO_2 to "blue solution" overset(NaOH)to "red solution." "Tube B"+HNO_2 to "No reaction" . "Tube C "+HNO_2 to "blue solution "overset(NaOH)to No reaction. Tube A, B and C contains_____________.

A capilary tube is kept vertical and made to touch the surface of the liquid of surface tension T . If the radius of the capillary tube is 'r' . Then the force on the wall of the capillary tube is

Pitot Tube

An ideal gas having density 1.7 xx 10^(-3) g cm ^(-3) at a preesure 1.5 xx 10^(5) pa is a filled Kundt tube. When the gas is resonnated at a frequency of 3.0 kHz, nodes an formed at a separation of 6.0 cm . Calculate the heat molar heat capacites (C_p and C_v) of the gas.
