QUES: Film speed is used in the exposure equations to find the appropriate exposure parameters. Four variables are available to the photographer to obtain the desired effect: lighting, film speed, f-number (aperture size), and shutter speed (exposure time). The equation may be expressed as ratios, or, by taking the logarithm (base 2) of both sides, by addition, using the APEX system, in which every increment of 1 is a doubling of exposure; this increment is commonly known as a "stop". The effective f-number is proportional to the ratio between the lens focal length and aperture diameter, the diameter itself being proportional to the square root of the aperture area. Thus, a lens set to f/1.4 allows twice as much light to strike the focal plane as a lens set to f/2. Therefore, each f-number factor of the square root of two (approximately 1.4) is also a stop, so lenses are typically marked in that progression: f/1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, 32, etc.
A lens with a setting of f/1.4 lets how much to hit the focal plane compared with a setting of f/2?

ANS: twice as much

QUES: Although the Israelites were divided into Twelve Tribes, the Jews (being one offshoot of the Israelites, another being the Samaritans) are traditionally said to descend mostly from the Israelite tribes of Judah (from where the Jews derive their ethnonym) and Benjamin, and partially from the tribe of Levi, who had together formed the ancient Kingdom of Judah, and the remnants of the northern Kingdom of Israel who migrated to the Kingdom of Judah and assimilated after the 720s BCE, when the Kingdom of Israel was conquered by the Neo-Assyrian Empire.
Who assimilated before the 720s BCE?

ANS: unanswerable

QUES: The city's FM radio band features RTE Radio 1, RTE 2fm, RTE lyric fm, RTE Raidio na Gaeltachta, Today FM, 4fm, Newstalk and the religious station Spirit Radio. There are also local stations such as Cork's 96FM, Cork's Red FM, C103, CUH 102.0FM, UCC 98.3FM (formerly Cork Campus Radio 97.4fm) and Christian radio station Life 93.1FM. Cork also has a temporary licensed city-wide community station 'Cork FM Community Radio' on 100.5FM, which is currently on-air on Saturdays and Sundays only. Cork has also been home to pirate radio stations, including South Coast Radio and ERI in the 1980s. Today some small pirates stations remain. A number of neighbouring counties radio stations can be heard in parts of Cork City including Radio Kerry at 97.0 and WLR FM on 95.1.
When were South Coast Radio and ERI running their pirate stations out of Cork?

ANS: 1980s

QUES: Rajasthan is famous for its forts, carved temples, and decorated havelis, which were built by Rajput kings in pre-Muslim era Rajasthan.[citation needed] Rajasthan's Jaipur Jantar Mantar, Mehrangarh Fort and Stepwell of Jodhpur, Dilwara Temples, Chittorgarh Fort, Lake Palace, miniature paintings in Bundi, and numerous city palaces and haveli's are part of the architectural heritage of India. Jaipur, the Pink City, is noted for the ancient houses made of a type of sandstone dominated by a pink hue. In Jodhpur, maximum houses are painted blue. At Ajmer, there is white marble Bara-dari on the Anasagar lake. Jain Temples dot Rajasthan from north to south and east to west. Dilwara Temples of Mount Abu, Ranakpur Temple dedicated to Lord Adinath in Pali District, Jain temples in the fort complexes of Chittor, Jaisalmer and Kumbhalgarh, Lodurva Jain temples, Mirpur Jain Temple, Sarun Mata Temple kotputli, Bhandasar and Karni Mata Temple of Bikaner and Mandore of Jodhpur are some of the best examples.
Which Pali District temple is dedicated to Lord Adinath?

ANS:
Ranakpur Temple
