How far away is the radio horizon of an antenna 100ft high?
A radio station antenna is 32 km away, 16° north of west with respect to an origin on a map. An office building is 37 km away, 33° east of north with respect to the origin. How far is the office building with respect to the radio station antenna, and in what direction is the office building as measured from the antenna? (a) the office building's distance from the antenna (b) the office building's direction from the antenna, measured counterclockwise...
A radio station antenna is 35 km away, 22° north of west with respect to an origin on a map. An office building is 36 km away, 36° east of north with respect to the origin. How far is the office building with respect to the radio station antenna, and in what direction is the office building as measured from the antenna? (Please draw a diagram) (a) the office building's distance from the antenna in km (b) the office building's...
How do I determine the broadcast frequency of a radio station that has an antenna 160 meters high? *Is there an equation for this?
The antenna for an AM radio station is a 62.5m high tower whose height is equal to one‑quarter the wavelength of the broadcast signal. At what frequency does the station transmit?
The antenna for an AM radio station is a 67.5 m high tower whose height is equal to one-quarter the wavelength of the broadcast signal. At what frequency does the station transmit? frequency:
The antenna for an AM radio station is a 73.5 m high tower whose height is equal to one‑quarter the wavelength of the broadcast signal. At what frequency does the station transmit? frequency:
The antenna for an AM radio station is a 55-m-high tower whose height is equivalent to one-quarter wavelength.1)At what frequency does the station transmit? (Express your answer to two significant figures.)
In an experiment to demonstrate interference, you connect two antennas to a single radio receiver. When the two antennas are adjacent to each other, the received signal is strong. You leave one antenna in place and move the other one directly away from the radio transmission tower. How far should the second antenna be moved in order to receive a minimum signal from a station that broadcasts at 95.4 MHz?
A tank circuit in a radio transmitter is a series RCL circuit connected to an antenna. The antenna broadcasts radio signals at the resonant frequency of the tank circuit. Suppose that a certain tank circuit in a shortwave radio transmitter has a fixed capacitance of 1.2 x 10-11 F and a variable inductance. If the antenna is intended to broadcast radio signals ranging in frequency from 4.6 MHz to 8.4 MHz, find the (a) minimum and (b) maximum inductance of...
A radio antenna broadcasts a 1.0 MHz radio wave with 25 kW power. Assume the radiation is emitted uniformly in all directions. 1) what is the wave's intensity 30 km from the antenna 2) what is the electric field amplitude at this distance?
