In a pond containing water, an air bubble is produced at a depth of 70 cm with respect to the surface of the water, if the radius of the bubble is R bubble = 2 cm, it determines the pressure of the air inside the bubble. Consider that the surface tension of water is: γ = 0.0725 N / m

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.
