Hiroshima1 essays

Hiroshima1 essays On August 6, 1945, a B-29 bomber named Enola Gay dropped an atomic bomb, "little boy" on Hiroshima, Japan. Hiroshima had been almost eradicated with an estimated 70-80,000 people killed. Three days later, a second, more powerful bomb was dropped on the Japanese city of Nagasaki, killing over 100,000 people. Since Japan was economically and militarily devastated by the late summer of 1945, the use of the atomic bombs on an already overcome Japan was unnecessary and unwarranted in bringing about a conclusion to the war in the Pacific. By the end of the war, the U.S. forces had pushed the Japanese far back into their country, leaving them no access to any resources from the Indies. Japanese cities and factories were being endlessly bombarded by American bombers. Louis Morton, an author on the situation felt that since ". . . The Pacific Fleet had driven the Imperial Navy from the ocean and planes of the fast carrier forces were striking Japanese naval bases in the Inland Sea. . . Clearly Japan was a defeated nation."1 The decision to use the atomic bomb was validated by the U.S., who said that the force was necessary to end the war, which, in turn, would save lives of both American and Japanese soldiers. However, many believe that since Japan was already of the verge of surrender when the bombs were dropped, this argument cannot be morally validated. If Japan was almost beaten by August 1945, many say that the reason the U.S. dropped the bomb was simply to test it on living humans. Aside from the ground test in the New Mexico desert, no one knew what destruction atomic weapons were capable of. Throughout the war, the city of Hiroshima had been left virtually untouched by U.S. attacks. It is inferable, then, that the United States government hoped to see the full effect of nuclear power by detonating the atomic bomb on this locality, as they could be sure that any damage was from the atomic bomb alone. A similar reasoning ...

How To Calculate Percent

How To Calculate Percent Calculating percent is a fundamental math skill, whether youre taking a class or just living life! Percentages are used to make car and house payments, calculate tips and pay taxes on goods. Percent calculations are fundamental to many classes, especially science courses. Heres a step-by-step tutorial on how to calculate percent. What Is Percent? Percentage or percent means per one hundred and expresses the fraction of a number out of 100% or the total amount. A percent sign (%) or the abbreviation pct is used to denote percentage. How To Calculate Percent Determine the total or whole amount. Divide the number to be expressed as a percent by the total.In most cases, youll divide the smaller number by the larger number.Multiple the resulting value by 100. Example Percent Calculation Say you have 30 marbles. If 12 of them are blue, what percent of the marbles are blue? What percent are not blue? Use the total number of marbles. This is 30.Divide the number of blue marbles into the total: 12/30 0.4Multiple this value by 100 to get the percent: 0.4 x 100 40% are blueYou have two ways to determine what percent are not blue. The easiest is to take the total percent minus the percent that are blue: 100% - 40% 60% not blue. You could calculate it, just like you did the initial blue marble problem. You know the total number of marbles. The number that is not blue is the total minus the blue marbles: 30 - 12 18 non-blue marbles.The percent that is not blue is 18/30 x 100 60%As a check, you can make sure the total of blue and non-blue marbles adds up to 100%: 40% 60% 100% Learn More How To Calculate Mass PercentHow To Calculate Percent Composition by MassPercent Error CalculationVolume Percent Concentration
