Calculate the reactance of capacitance in an AC circuit wherein the input signal has a frequency of 100 Hz and a capacitor has a capacitance of 1000mF in a circuit.

A coil of self inductance 20mH is connected to an a.c source of 220v and of frequency 50Hz. What is the inductive reactance and r.m.s current in the circuit?

Calculate the wavelength of a sound wave whose frequency is 220 Hz and speed is 440m/s in a given medium'.

A source of sound is movig with a speed 220 m(s)^-1 towards a stationary target.While moving,it emits a wave of frequency 1000 Hz.Some of the sound reaching the target get reflected back to the source as echo.Calculate the (i)frequency of sound as detected by the target and (ii)the frequency of echo as detected by the source?
