Ccording to its directional distribution, solar radiation incident on the earth's surface may be divided into two components. the direct component consists of parallel rays incident at a fixed zenith angle θ, while the diffuse component consists of radiation that may be approximated as being diffusely distributed with θ. consider clear sky conditions for which the direct radiation is incident at θ = 30°, with a total flux (based on an area that is normal to the rays) of ir 1000 w/m2, and the total intensity of the diffuse radiation is 1,lif 70 w/m2. sr. what is the total solar irradiation at the earth's surface?

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.
