QUES: In 1926 Joseph P. Maxwell and Henry C. Harrison from Bell Telephone Laboratories disclosed that the recording pattern of the Western Electric "rubber line" magnetic disc cutter had a constant velocity characteristic. This meant that as frequency increased in the treble, recording amplitude decreased. Conversely, in the bass as frequency decreased, recording amplitude increased. Therefore, it was necessary to attenuate the bass frequencies below about 250 Hz, the bass turnover point, in the amplified microphone signal fed to the recording head. Otherwise, bass modulation became excessive and overcutting took place into the next record groove. When played back electrically with a magnetic pickup having a smooth response in the bass region, a complementary boost in amplitude at the bass turnover point was necessary. G. H. Miller in 1934 reported that when complementary boost at the turnover point was used in radio broadcasts of records, the reproduction was more realistic and many of the musical instruments stood out in their true form.
What happens when frequency decreases in the bass?

ANS: recording amplitude increased

QUES: Historically, there has been much dispute over whether such a thing as a vacuum can exist. Ancient Greek philosophers debated the existence of a vacuum, or void, in the context of atomism, which posited void and atom as the fundamental explanatory elements of physics. Following Plato, even the abstract concept of a featureless void faced considerable skepticism: it could not be apprehended by the senses, it could not, itself, provide additional explanatory power beyond the physical volume with which it was commensurate and, by definition, it was quite literally nothing at all, which cannot rightly be said to exist. Aristotle believed that no void could occur naturally, because the denser surrounding material continuum would immediately fill any incipient rarity that might give rise to a void.
What did Greek philosophers believe could not occur naturally?

ANS: unanswerable

QUES: Thus, Buckingham Palace is a symbol and home of the British monarchy, an art gallery and a tourist attraction. Behind the gilded railings and gates which were completed by the Bromsgrove Guild in 1911 and Webb's famous façade, which has been described in a book published by the Royal Collection as looking "like everybody's idea of a palace", is not only a weekday home of the Queen and Prince Philip but also the London residence of the Duke of York and the Earl and Countess of Wessex. The palace also houses the offices of the Queen, Prince Philip, Duke of York, Earl and Countess of Wessex, Princess Royal, and Princess Alexandra, and is the workplace of more than 800 people.
Buckingham Palace is also the London Residence for which Duke?

ANS: Duke of York

QUES: In some modern day nations and regions in which Sharia law is ostensibly practiced, heresy remains an offense punishable by death. One example is the 1989 fatwa issued by the government of Iran, offering a substantial bounty for anyone who succeeds in the assassination of author Salman Rushdie, whose writings were declared as heretical.
What author was declared a heretic and had a bounty placed on his head by the government of Iran?

ANS:
Salman Rushdie
