Context and question: The standing wave forms with this desired pattern at the design frequency, f0, and antennas are normally designed to be this size. However, feeding that element with 3f0 (whose wavelength is 13 that of f0) will also lead to a standing wave pattern. Thus, an antenna element is also resonant when its length is 34 of a wavelength. This is true for all odd multiples of 14 wavelength. This allows some flexibility of design in terms of antenna lengths and feed points. Antennas used in such a fashion are known to be harmonically operated.
What can be added to f0 to create a standing wave pattern?
Answer: 3f0
Context and question: Like Finnish, Estonian employs the Latin script as the basis for its alphabet, which adds the letters a, o, u, and o, plus the later additions s and z. The letters c, q, w, x and y are limited to proper names of foreign origin, and f, z, s, and z appear in loanwords and foreign names only. O and u are pronounced similarly to their equivalents in Swedish and German. Unlike in standard German but like Finnish and Swedish (when followed by 'r'), A is pronounced [], as in English mat. The vowels A, O and U are clearly separate phonemes and inherent in Estonian, although the letter shapes come from German. The letter o denotes //, unrounded /o/, or a close-mid back unrounded vowel. It is almost identical to the Bulgarian // and the Vietnamese o, and is used to transcribe the Russian .
What letters are not limited to proper names of foreign origin?
Answer: unanswerable
Context and question: The Gorals of southern Poland and northern Slovakia are partially descended from Romance-speaking Vlachs who migrated into the region from the 14th to 17th centuries and were absorbed into the local population. The population of Moravian Wallachia also descend of this population.
Where do Moravian Wallachia live?
Answer:
unanswerable
