  • A sensor to find liquid level in a tank is a cylindrical capacitor of length with outer and conductor radii R_(0) and R_(i) respectively. When a liquid fills the tank up to height h, (h le l) tank.s bottom the dielectric in lower part is liquid (K_l) and dielectric in upper part is vapour liquid (K_r) When liquid fills the tank up to height h, the capacity of capacitor is

    What is Doppler effect? Obtain an expression for the apparent frequency of sound heard when the source is in motion with respect to an observer at rest. A train sounds its whistle as it approaches and crosses a level crossing. An observer at the crossing measures a frequency of 219 Hz as the train approaches and a frequency of 184 Hz as it leaves. If the speed of sound is taken to be 340 m/s, find the speed of the train and the frequency of its whistle.
