QUES: In 1961, Nasser sought to firmly establish Egypt as the leader of the Arab world and to promote a second revolution in Egypt with the purpose of merging Islamic and socialist thinking. To achieve this, he initiated several reforms to modernize al-Azhar, which serves as the de facto leading authority in Sunni Islam, and to ensure its prominence over the Muslim Brotherhood and the more conservative Wahhabism promoted by Saudi Arabia. Nasser had used al-Azhar's most willing ulema (scholars) as a counterweight to the Brotherhood's Islamic influence, starting in 1953.

What religious group was Nasser seeking to marginalize?
What is the answer?
ANS: Muslim Brotherhood
QUES: The "orange peel" effect on vinyl records is caused by worn molds. Rather than having the proper mirror-like finish, the surface of the record will have a texture that looks like orange peel. This introduces noise into the record, particularly in the lower frequency range. With direct metal mastering (DMM), the master disc is cut on a copper-coated disc, which can also have a minor "orange peel" effect on the disc itself. As this "orange peel" originates in the master rather than being introduced in the pressing stage, there is no ill effect as there is no physical distortion of the groove.

What is the expected finish of a vinyl record?
What is the answer?
ANS: mirror-like
QUES: For maximum life, capacitors usually need to be able to handle the maximum amount of reversal that a system will experience. An AC circuit will experience 100% voltage reversal, while under-damped DC circuits will experience less than 100%. Reversal creates excess electric fields in the dielectric, causes excess heating of both the dielectric and the conductors, and can dramatically shorten the life expectancy of the capacitor. Reversal ratings will often affect the design considerations for the capacitor, from the choice of dielectric materials and voltage ratings to the types of internal connections used.

What percentage of voltage reversal will an over damped DC circuit experience?
What is the answer?
ANS:
unanswerable
