Hace 1 día · Physical, or absolute, water scarcity is the result of a region’s demand outpacing the limited water resources found there. According to the Food and Agricultural Organization (FAO) of the United Nations, around 1.2 billion people live in areas of physical scarcity; many of these people live in arid or semi-arid regions.
Hace 4 días · Electrolysis, process by which electric current is passed through a substance to effect a chemical change. The chemical change is one in which the substance loses or gains an electron (oxidation or reduction). Learn more about electrolysis in this article.
The solutions are obtained by replacing \(t\) with \(−t\). The solutions, orbits and direction fields can be seen in Figures 2.8-2.9. This is once again a node, but all orbits lead away from the equilibrium point. It is called an unstable node or a source. Figure 2.8. Plots of solutions of Example 2.6 for several initial conditions.
