a sound wave , which speed is 500m/s , transmits along negative direction of X axis without energy decrease in medium which density is 0.25Kg/m³.Accordingly,vibration equation of material particle,which lateral coordinates is 0.5π meter,is 2cos(2000t-π/2)millimeter. a)Calculate the wav...
This is why it is important to pick your MP3 cutter for Mac wisely while taking into consideration a wide range of factors. Some of the top factors include reliability, performance, cost, and ease of use. If you are just a beginner in this space or don't want access to highly advanced...
PROBLEM TO BE SOLVED: To provide a small-sized antenna whose size is reduced by using the resonance phenomenon in a high speed wave leakage mode, which is mounted on a printed circuit board with the surface mount technology and can be built on a dielectric material whose specific dielectric ...
For the pointing accuracy to be correct, you must make sure that your location is set and that the mount is polar aligned and balanced. The Star Adventurer GTi has a robust wedge base suitable for mounting cameras with long telephoto lenses and compact telescopes. ...
, and is starting to look quite similar to a wave equation. In fact, this equation can solve up to and around the resonance of a structure under the assumption that there is negligible radiation, as demonstrated in this example:Modeling of a 3D Inductor. ...
Answer to: The speed at which a wave propagates down a string is 300 m/s. If the frequency of this wave is 150 Hertz, what is the wavelength of...
