Accounting Rate of Return (ARR) ARR provides a quick estimate of a project’s worth over its useful life. ARR is derived by finding profits before taxes and interest. ARR is an accounting method used for purposes of comparison. The major drawbacks of ARR are that it uses profit rather than cash flows‚ and it does not account for the time value of money. ARR is most often used internally when selecting projects. It can also be used to measure the performance of projects and subsidiaries within

Review of Literature: High employee turnover rate is problem and because of this many industries have been suffering from losses in term of money and trained mind as well. Many research have been conducted on these topic to find out all reasons behind high employee turnover rate and suggested different ways to deal with but we know because of globalization over market is dynamic and because of dynamism working

Natural rate of unemployment The natural rate of unemployment (sometimes called the structural unemployment rate) is a concept of economic activity developed in particular by Milton Friedman and Edmund Phelps in the 1960s‚ both recipients of the Nobel prize in economics. In both cases‚ the development of the concept is cited as a main motivation behind the prize.[1][2] It represents the hypothetical unemployment rate consistent with aggregate production being at the "long-run" level. This level

“Countries grow at different rates because they accumulate capital at different rates.” Is this true? Explain your answer. Since the Industrial Revolution‚ economists have attempted to explain why certain countries economies grow at greater rates than others. The post-Keynesian era saw the introduction of the Harrod-Domar model of economic growth. This model explained an economy’s growth rate by observing the level of saving and productivity of capital in the economy. The neo-classical Solow-Swann

initial rate of reaction. I will measure the effect of the enzyme in 5 different concentrations against the controlled variable of the reactant. The enzyme which will be used is different concentrations of potato and the reactant used will be Hydrogen Peroxide. Hydrogen Peroxide which will be the buffer solution is a PH of 7.2. My hypothesis for the experiment is that as the concentration of the enzyme is increased the rate of reaction will be increased‚ producing oxygen at a faster rate. The results

Aim: The rate at which a reaction occurs‚ or takes place‚ is affected by various factors‚ such as the temperature at which the experiment is conducted in‚ the pressure which is given‚ the surface area which is exposed‚ use of catalysts‚ and the concentration. In this investigation‚ I would be investigating the affect of surface area‚ or particle size‚ in the rate at which a reaction occurs. Background Information: The more finely divided the solid is‚ the faster the reaction happens. A powdered

Determination of Rate and Order of a Reaction Results This experiment used a spectrometer to find the wavelength with maximum absorbance in a green food coloring solution. For this particular solution the wavelength was 629.7 nm. The system was then calibrated to that and was set to measure the food coloring and bleach solution. The measured visible light absorbance of the mixed solution was collected over a time of 200 seconds and eight points were then selected and placed into the Absorbance
