In a waterfall, water falls 100 ft. Assume all the potential energy change increases its enthalpy (or internal energy, in this case they change by the same amount because this is an incompressible liquid). Assume the specific heat capacity for water is equal to 1.0008 Btu/(lbm·°F). Calculate the temperature rise of the water in °F. (6 points)

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.
