Other contemporary observations also described this aurora as being: “quite close above the Moon”; “aurora crossing the Moon”; aurora being “just over the Moon, a green arch”; and a “stationary arc 30 degrees to 40 degrees above horizon and above the Moon” (Capron, 1883, pp. 320...
It seems that the latest developments in the aerospace field regarding such sensors open now a window for their automotive application. Low cost microwave radars have emerged at the 77 GHz frequency, able to be seen 200 m in front, whereas far infrared sensor cost has been reduced by up to...
\\ (a) What is the frequency of the sound received by a stationary observer if the source moves towards her? \\ (b) Now, the source moves away from A source emits sound, at a fixed constant frequency, f. If the source moves, the wavelength of the sound...
