there should be 7 values of x. Thanks. A radio transmitting station operating at a frequency of 115 MHz has two identical antennas that radiate in phase. Antenna B is 9.00 m to the right of antenna A. Consider point P between the antennas and along the line connecting them, a horizontal distance x to the right of antenna A. Part A For what values of x will constructive interference occur at point P? Express your answers in meters. Enter...

We would like to build an AM radio receiver using a series RLC circuit working as a bandpass filter. We have decided to use a 240 μH inductor with an internal resistance of 12Ω, and a variable capacitor whose capacitance varies between 40 to 360 pF. A radio “tunes” into a certain frequency by adjusting its receiver circuit so that it resonates at that frequency, and it only catches that specific frequency. 1. Determine the range of channel frequencies that...
