The Relationship between Risks and Rate of Returns

The risk and rate of return, as discussed in business, are directly proportional. It means that as the risk increases, the rate of return increases while as the risk declines, the rate of return decreases as well (Christoffersen, 2012). Therefore, an individual willing to invest must take a decision based on both the risk and rate of return analysis to achieve a high return at a lower risk. Investors are likely to prefer investment decisions that yield high rates of return at minimal risks. The term risk defines the capability of acquiring loss below a person’s investigations. On ...

Introduction: All most all metals are unstable when exposed to air. This is because of the tendency of the metal to be converted into its oxidized form on reaction with air. When compared to zinc, iron has a greater tendency to form oxidized form and thus has greater susceptibility to corrosion. The ability of metals to react with air varies and this determines their relative stability. As zinc is much stable when compared to iron, it is used to galvanizing iron pipe, thus preventing contact of iron with air and water that contains dissolved air. Brass is an alloy ...
