Question: The quality of a partial vacuum refers to how closely it approaches a perfect vacuum. Other things equal, lower gas pressure means higher-quality vacuum. For example, a typical vacuum cleaner produces enough suction to reduce air pressure by around 20%. Much higher-quality vacuums are possible. Ultra-high vacuum chambers, common in chemistry, physics, and engineering, operate below one trillionth (1012) of atmospheric pressure (100 nPa), and can reach around 100 particles/cm3. Outer space is an even higher-quality vacuum, with the equivalent of just a few hydrogen atoms per cubic meter on average. According to modern understanding, even if all matter could be removed from a volume, it would still not be "empty" due to vacuum fluctuations, dark energy, transiting gamma rays, cosmic rays, neutrinos, and other phenomena in quantum physics. In the electromagnetism in the 19th century, vacuum was thought to be filled with a medium called aether. In modern particle physics, the vacuum state is considered the ground state of matter.
Try to answer this question if possible: If all matter is removed from a vacuum, would it be empty space?
Answer: it would still not be "empty"
Question: The American Idol Songwriter contest was also held this season. From ten of the most popular submissions, each of the final two contestants chose a song to perform, although neither of their selections was used as the "coronation song". The winning song, "The Time of My Life", was recorded by David Cook and released on May 22, 2008.
Try to answer this question if possible: What was the name of the first song released by David Cook after winning American Idol?
Answer: The Time of My Life
Question: The archipelago has a wet oceanic climate with pleasant temperatures but consistent moderate to heavy rainfall and very limited sunshine, due to the persistent westerly winds. The number of rainy days is comparable to the Aleutian Islands at a much higher latitude in the northern hemisphere, while sunshine hours are comparable to Juneau, Alaska, 20 farther from the equator. Frost is unknown below elevations of 500 metres (1,600 ft) and summer temperatures are similarly mild, never reaching 25 C (77 F). Sandy Point on the east coast is reputed to be the warmest and driest place on the island, being in the lee of the prevailing winds.
Try to answer this question if possible: What has a wet oceanic climate with unpleasant temperatures?
Answer: unanswerable
Question: While they have played in suburban Foxborough since 1971, the New England Patriots of the National Football League were founded in 1960 as the Boston Patriots, changing their name after relocating. The team won the Super Bowl after the 2001, 2003, 2004, and 2014 seasons. They share Gillette Stadium with the New England Revolution of Major League Soccer. The Boston Breakers of Women's Professional Soccer, which formed in 2009, play their home games at Dilboy Stadium in Somerville.
Try to answer this question if possible: What league do the new England patriots belong to?
Answer:
the National Football League
