The trans-siberian railroad is the longest single railroad in the world. starting in moscow, the tracks stretch 9,354 km across the siberian frontier to vladivostok, at the edge of the pacific ocean. if you were to leave moscow and travel on the railroad with an average speed of 90.0 km/h, how long would it take for you to reach vladivostok?

The key to stability is feedback between the reservoir and the fluxes into and/or out of the reservoir. assume that the rate of outflow from a reservoir depends on the size of the reservoir according to the following relationship: outflow rate= k x (size of reservoir), where k is a constant. a reservoir of water has a volume of 5000 liters, and the rate of outflow at steady state is 25 liters per minute. what is k? (give both the numerical value and its units.) what is the residence time? what is the relationship between k and the residence time?

Elements on the periodic table are ordered according to their
