Explanation:
Since this situation can be thought of as a direct variation. multiply 20000 with 100 and divide the product with 1500.
A radio station broadcast on a frequency of 3.7 mhz what is the energy of the radio wave A radio station broadcasts its programmes at a wavelength of 500 m. Find the frequency of the radiowaves transmitted by the radio station, if the speed of radiowaves in air is 3 x 108 m/s. Ans: 6 x 10 Hz
<h3>What is
radio station ?</h3>
Radio broadcasting is the act of sending audio (sound), occasionally together with accompanying metadata, across radio waves to radio receivers used by the general public. Unlike satellite radio, which uses a satellite in Earth's orbit, terrestrial radio broadcasting uses a land-based radio station to transmit radio waves. The listener needs a broadcast radio receiver to hear the material (radio). A radio network with which stations frequently have affiliations provide content in a standard radio format, whether through broadcast syndication, simulcasting, or both. Radio stations use a variety of modulations to transmit their signals, including FM (frequency modulation), which is an older analog audio standard, and AM (amplitude modulation).

Scientists believe that most animals survived the 2004 Asian Tsunami because they had perceived its coming and they prepared for it. It is believed that animals can hear and perceive infrasonic sound and Rayleigh waves which are usually the warming signs of a coming tsunami. Scientists believed that the animals felt the shaking of the ground as a result of the Rayleigh waves and hear the infrasonic sounds which can not be heard by humans. This makes the animals to flee to higher grounds [above sea level] for safety.
