input question: Given the background: Centripetal force is, simply, the force that causes centripetal acceleration. Objects that move in uniform circular motion all have an acceleration toward the center of the circle and therefore, they must also suffer a force toward the center of the circle. That force is the centripetal force. For orbiting satellites, such as the moon orbiting the earth or the earth orbiting the sun, the centripetal force is produced by gravity. When an Olympic hammer thrower whirls a massive ball on a chain, the centripetal force is created by the athlete and transmitted by the chain. and the situation: Adam wants to show his little brother a trick. He gets a bucket of water and says to him "I bet i can turn this bucket upside down and no water will fall out". His brother doesn't believe him of course. So Adam takes the bucket by the handle and quickly starts spinning it in a circle. Answer the following question: Will the centripetal force on the bucket increase or decrease as Adam spins it faster????
output answer: increase

input question: Given the background: When the Moon is at first quarter or third quarter, the Sun and Moon are separated by 90 when viewed from the Earth, and the solar tidal force partially cancels the Moon's tidal force. At these points in the lunar cycle, the tide's range is at its minimum; this is called the neap tide, or neaps. Neap is an Anglo-Saxon word meaning "without the power", as in forganges nip (forth-going without-the-power).Spring tides result in high waters that are higher than average, low waters that are lower than average, 'slack water' time that is shorter than average, and stronger tidal currents than average. Neaps result in less extreme tidal conditions. There is about a seven-day interval between springs and neaps. and the situation: Rob was in the East Coast for a month. He had the good opportunity to see various tidal conditions. First he saw the spring tide, which he noted as case A. About a week later he saw the neap tide. He noted that as case B. Rob got curious about the science behind various tidal conditions. Answer the following question: Which case would result in more extreme tidal conditions, case A or case B????
output answer: case A

input question: Given the background: An equilibrium can also be disrupted by the full or partial removal of a reactant or product. If the concentration of a substance is decreased, the system will respond by favoring the reaction that replaces that substance. In the industrial Haber-Bosch process, NH 3 is removed from the equilibrium system as the reaction proceeds. As a result, the forward reaction is favored so that more NH 3 will be produced. The concentrations of N 2 and H 2 decrease. Continued removal of NH 3 will eventually force the reaction to go to completion until all of the reactants are used up. If either N 2 or H 2 were removed from the equilibrium system, the reverse reaction would be favored, and the concentration of NH 3 would decrease. and the situation: Jennifer and Justin are examining the principle of chemical equilibrium in their second year organic chemistry course. They are performing a reaction that involves hydrogen gas and glucose as the starting reactants, and the products formed in the reaction are carbon dioxide and oxygen gas. Jennifer and Justin add the materials, and then wait until the reaction has reached equilibrium. Afterwards, Jennifer removes glucose from her reaction mixture, while Justin removes carbon dioxide from his reaction mixture. Answer the following question: Which person's reaction, Jennifer's or Justin's, will begin producing less oxygen gas????
output answer: Jennifer's

input question: Given the background: The Mercator projection is best within 15 degrees north or south of the equator. Landmasses or countries outside that zone get stretched out of shape. The further the feature is from the equator, the more out of shape it is stretched. For example, if you look at Greenland on a globe, you see it is a relatively small country near the North Pole. Yet, on a Mercator projection, Greenland looks almost as big the United States. Because Greenland is closer to the pole, the continent's shape and size are greatly increased. The United States is closer to its true dimensions. and the situation: Bob is looking at a map with Mercator projection to help him with his geography class. He noticed that Ecuador is within fifteen degrees north or south of the equator, but Norway is farther north of the equator. Bob starts to see how a country's location on a map affects how they look. Answer the following question: Would Norway's shape and size increase or decrease on a map????
output answer:
increase
