Radio receiver receives a message at 300m band, If the available inductance is lmH, then calculate required capacitance.

A receiver reconstructs the original message after propagation through the channel. It

A radio station is broadcasting programmes as 100 MHz frequency if the distance between the ratio station and the received set is 300 km how long the signal would take in reach the set from the radio station ? Also calculate the wavelength and wavelength of radio waves

A source of sound of frequency 300 Hz and a receiver are located along the same line normal to the wall as shown in the figure. Both the source and the receiver are stationary and the wall receeds from the source with velocity 20ms^-1 .If the beat frequency registered by the receiver is 240/x Hz then x is : (Assume V_("sound")=300 m/s).

An electro magnetic wave of wavelength 300 metre can be transmitted by a transmission centre. A condenser of capacity 2.5muF is available. Calculate the inductance of the required coil for a resonant circuit.Use pi^(2)=10 .

A transmitting station transmits radiowave of wavelength 360 m. What is the inductance of a coil required with a condenser of capacity 1.20 mu F in the resonant circuit to receive the radiowaves ? ( Use pi^2 =10)

A series circuit consists of a resistance, inductance and capacitance. The apllied voltage and the current at any instant are given as e=141.4 cos (300t-10^(@)) and i=5 cos (3000t-55^(@)) The inductance is 0.01H. Calculate the values of the resistance and capacitance.
