1. Calculate the acceleration for the two sets of data you recorded and compare these values to those obtained by measuring distance and time using percent error. Cite two factors that may cause discrepancies between the two values. 2. Calculate the tension in the string for the falling washers. Show all calculations. From these two values, and the one where the masses were equal, what trend do you observe in the tension in the string as the acceleration increases

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.
