Context and question: New York City has a high degree of income disparity as indicated by its Gini Coefficient of 0.5 for the city overall and 0.6 for Manhattan. The disparity is driven by wage growth in high-income brackets, while wages have stagnated for middle and lower-income brackets. In the first quarter of 2014, the average weekly wage in New York County (Manhattan) was $2,749, representing the highest total among large counties in the United States. In 2013, New York City had the highest number of billionaires of any city in the world, higher than the next five U.S. cities combined, including former Mayor Michael R. Bloomberg. New York also had the highest density of millionaires per capita among major U.S. cities in 2014, at 4.6% of residents. Lower Manhattan has been experiencing a baby boom, with the area south of Canal Street witnessing 1,086 births in 2010, 12% greater than 2009 and over twice the number born in 2001.
By 2013, which city had the most billionaires living in the city?
Answer: New York City
Context and question: Equivalently, the smallness of the Planck constant reflects the fact that everyday objects and systems are made of a large number of particles. For example, green light with a wavelength of 555 nanometres (the approximate wavelength to which human eyes are most sensitive) has a frequency of 7014540000000000000♠540 THz (7014540000000000000♠540×1012 Hz). Each photon has an energy E = hf = 6981358000000000000♠3.58×10−19 J. That is a very small amount of energy in terms of everyday experience, but everyday experience is not concerned with individual photons any more than with individual atoms or molecules. An amount of light compatible with everyday experience is the energy of one mole of photons; its energy can be computed by multiplying the photon energy by the Avogadro constant, NA ≈ 7023602200000000000♠6.022×1023 mol−1. The result is that green light of wavelength 555 nm has an energy of 7005216000000000000♠216 kJ/mol, a typical energy of everyday life.
Which light wavelength is the human eye no longer able to see?
Answer: unanswerable
Context and question: Britain now threatened to withdraw its subsidies if Prussia didn't consider offering concessions to secure peace. As the Prussian armies had dwindled to just 60,000 men and with Berlin itself under siege, Frederick's survival was severely threatened. Then on 5 January 1762 the Russian Empress Elizabeth died. Her Prussophile successor, Peter III, at once recalled Russian armies from Berlin (see: the Treaty of Saint Petersburg (1762)) and mediated Frederick's truce with Sweden. He also placed a corps of his own troops under Frederick's command This turn of events has become known as the Miracle of the House of Brandenburg. Frederick was then able to muster a larger army of 120,000 men and concentrate it against Austria. He drove them from much of Saxony, while his brother Henry won a victory in Silesia in the Battle of Freiberg (29 October 1762). At the same time, his Brunswick allies captured the key town of Göttingen and compounded this by taking Cassel.
How many troops did Frederick have left?
Answer:
60,000 men
