What is the potential energy of a 150 kg diver standing on a diving board that is 10 m high? the potential energy is j

The formula for potential energy would be PE = mgh Where: m is the mass; g is the acceleration due to gravity, and h would be height. So plugging in the data: PE = 150kg × 9.8 m/s^2 × 10m = 14700 Joules would be the potential energy for this problem.

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.
