Moe is carrying and supporting a large crate by exerting 1000 n. he is walking at constant velocity across a level, horizontal floor. if he covers a distance of 10 meters, how much work does he do on the crate

The work done by a constant force is equal to 

where
F is the magnitude of the force
d is the displacement through which the force is applied

In our problem, the force applied by Moe is F=1000 N, and the distance covered by applying this force is d=10 m. Therefore, the work done by Moe is

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.
