The SI unit for acceleration is metre per second squared (m s −2). Accelerations are vector quantities (they have magnitude and direction) and add according to the parallelogram law. [6] [7] As a vector, the calculated net force is equal to the product of the object's mass (a scalar quantity) and its acceleration.
Disc-At-Once (DAO) for CD-R media is a mode that masters the disc contents in one pass, rather than a track at a time as in Track At Once. DAO mode, unlike TAO mode, allows any amount of audio data (or no data at all) to be written in the "pre-gaps" between tracks.
For 拉 (MC lop), the expected Kan reading /rapu > rō/ is not found in Sino-Japanese vocabulary, but only /raQ/ as in 拉致 /raQ.ti/ [ɾattɕi] 'abduction' (shortened in most words to /ra/). However, for many characters, the vowel-final readings have been extended to all environments.
The Peabody Picture Vocabulary Test, the 2007 edition of which is known as the PPVT-IV, is an untimed test of receptive vocabulary for Standard American English and is intended to provide a quick estimate of the examinee's receptive vocabulary ability. It can be used with the Expressive Vocabulary Test-Second Edition (EVT-2) to make a direct ...
A defining vocabulary is a list of words used by lexicographers to write dictionary definitions. The underlying principle goes back to Samuel Johnson's notion that words should be defined using 'terms less abstruse than that which is to be explained', [1] and a defining vocabulary provides the lexicographer with a restricted list of high-frequency words which can be used for producing simple ...
An example of a controlled vocabulary which is usable for indexing web pages is PSH. It is unlikely that a single metadata scheme will ever succeed in describing the content of the entire Web. [11] To create a Semantic Web, it may be necessary to draw from two or more metadata systems to describe a Web page's contents.
The following conventions are used: Cognates are in general given in the oldest well-documented language of each family, although forms in modern languages are given for families in which the older stages of the languages are poorly documented or do not differ significantly from the modern languages.
Teachers and curriculum developers should bear in mind that any attention to form, i.e., grammar or vocabulary, increases the likelihood that learners may be distracted from the task itself and become preoccupied with detecting and correcting errors and/or looking up language in dictionaries and grammar references.
