The relative pitches of individual notes in a scale may be determined by one of a number of tuning systems. In the west, the twelve-note chromatic scale is the most common method of organization, with equal temperament now the most widely used method of tuning that scale. In it, the pitch ratio between any two successive notes of the scale is exactly the twelfth root of two (or about 1.05946). In well-tempered systems (as used in the time of Johann Sebastian Bach, for example), different methods of musical tuning were used. Almost all of these systems have one interval in common, the octave, where the pitch of one note is double the frequency of another. For example, if the A above middle C is 440 Hz, the A an octave above that is 880 Hz (info).
What is the most common method of organization?
A: twelve-note chromatic scale

The ordinary half-wave dipole is probably the most widely used antenna design. This consists of two 14-wavelength elements arranged end-to-end, and lying along essentially the same axis (or collinear), each feeding one side of a two-conductor transmission wire. The physical arrangement of the two elements places them 180 degrees out of phase, which means that at any given instant one of the elements is driving current into the transmission line while the other is pulling it out. The monopole antenna is essentially one half of the half-wave dipole, a single 14-wavelength element with the other side connected to ground or an equivalent ground plane (or counterpoise). Monopoles, which are one-half the size of a dipole, are common for long-wavelength radio signals where a dipole would be impractically large. Another common design is the folded dipole, which is essentially two dipoles placed side-by-side and connected at their ends to make a single one-wavelength antenna.
What antenna type is a portion of the half wave dipole?
A: Monopoles

In 1579 a number of the northern provinces of the Low Countries signed the Union of Utrecht, in which they promised to support each other in their defence against the Spanish army. This was followed in 1581 by the Act of Abjuration, the declaration of independence of the provinces from Philip II.
Who declared their independence from Philip II in 1579?
A: unanswerable

Unlike all other British Government records, the records from the East India Company (and its successor the India Office) are not in The National Archives at Kew, London, but are held by the British Library in London as part of the Asia, Pacific and Africa Collections. The catalogue is searchable online in the Access to Archives catalogues. Many of the East India Company records are freely available online under an agreement that the Families in British India Society has with the British Library. Published catalogues exist of East India Company ships' journals and logs, 16001834; and of some of the Company's daughter institutions, including the East India Company College, Haileybury, and Addiscombe Military Seminary.
Where are the records of the EIC housed today?
A:
British Library in London
