Suppose you have a machine with a metal disk in it mounted to spin about its center. If the disk has a radius of 0.9 meters, and a mass of 5 kilograms, how much force would you have to apply to its edge to get it spinning at 1200 revolutions per minute. Assume the force is applied for 11 seconds. Give your answer in newtons (N).

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
