The volume of the tank is 1000 L. From earlier experiments it has been determined that 120 grams of new yeast are produced for each kilogram of nutrient that is consumed. In two separate trials, the system is allowed to reach equilibrium. In both trials the nutrient concentration of the inflow is 0.2 kg/L. In the first trial the inflow rate is 1 L/hr, and the system reaches an equilibrium population with 23.5 kg of yeast in the tank. In the second trial the inflow rate is 10 L/hr, and the system reaches an equilibrium population with 15.7 kg of yeast in the tank. What are the values of the constants a and R

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.
