QUES: Doubly fed electric motors have two independent multiphase winding sets, which contribute active (i.e., working) power to the energy conversion process, with at least one of the winding sets electronically controlled for variable speed operation. Two independent multiphase winding sets (i.e., dual armature) are the maximum provided in a single package without topology duplication. Doubly-fed electric motors are machines with an effective constant torque speed range that is twice synchronous speed for a given frequency of excitation. This is twice the constant torque speed range as singly-fed electric machines, which have only one active winding set.

What type of motor has three independent multiphase winding sets?
What is the answer?
ANS: unanswerable
QUES: European Dutch remained the literary language until the start of the 1920s, when under pressure of Afrikaner nationalism the local "African" Dutch was preferred over the written, European-based standard. In 1925, section 137 of the 1909 constitution of the Union of South Africa was amended by Act 8 of 1925, stating "the word Dutch in article 137 [...] is hereby declared to include Afrikaans". The constitution of 1983 only listed English and Afrikaans as official languages. It is estimated that between 90% to 95% of Afrikaans vocabulary is ultimately of Dutch origin.

What pressure influenced the shift in South Africa from the use of European Dutch in the 1920s?
What is the answer?
ANS: Afrikaner nationalism
QUES: The offices of elder and ministerial servant were restored to Witness congregations in 1972, with appointments made from headquarters (and later, also by branch committees). It was announced that, starting in September 2014, appointments would be made by traveling overseers. In a major organizational overhaul in 1976, the power of the Watch Tower Society president was diminished, with authority for doctrinal and organizational decisions passed to the Governing Body. Since Knorr's death in 1977, the position of president has been occupied by Frederick Franz (19771992) and Milton Henschel (19922000), both members of the Governing Body, and since 2000 by Don A. Adams, not a member of the Governing Body. In 1995, Jehovah's Witnesses abandoned the idea that Armageddon must occur during the lives of the generation that was alive in 1914 and in 2013 changed their teaching on the "generation".

In 1976 whose power in Watch Tower Society was diminished?
What is the answer?
ANS:
president
