an object's weight is caused by a downward force of gravity of 10N. A man lifts the object by applying an upward force of 30N. At the same time, a second man exerts a horizontal force of 50N on the object by pulling it along the ground. 1. draw a labelled force diagram to indicate how the force's are applied on the object.​

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.
