A satellite was launched in order to observe the Saturn. At the moment the distance between the satellite and the Saturn was

10 km with an attractive force 10,000 N. While after 20

seconds, the distance decreased to 5 km, what is the force

then (in N)?

Ifeel like lily and ledbetter had a fair pay act just because it was necessary especially at those times

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.
