DERIVATION OF FORMULAS constant acceleration In order to be accurate‚ the title of this section should be "One Dimensional Equations of Motion for Constant Acceleration". Given that such a title would be a stylistic nightmare‚ let me begin this section with the following qualification. The equations of motion are valid only when acceleration is constant and motion is constrained to a straight line. Given that we live in a three dimensional universe in which the only constant is change‚ you may

PHY 114: Absorption of Nuclear Radiation Abstract: The purpose of this experiment was to determine the mass thickness attenuation factor for beta rays when they pass through polyethylene sheets of varying thicknesses. This was done by using an apparatus that measured the seven different intensities and then taking these values‚ putting them through a number of calculations and finally generating a graph of ln(I_corr) versus the thickness of the polyethylene sheets. Once this graph

• Profitability Procter & Gamble’s Gross Profit Margin (GPM) increased in 2010 by 2.41%‚ however it decreased in 2011 by 1.34%‚ while Net Sales continued to increase from 2009 to 2011. This trend was due to a price fluctuation in Cost of Goods Sold. The GPM directly affected the Operating Profit Margin (OPM)‚ which also increased in 2010 by 0.25% and decreased in 2011 by 1.14%. The Operating expenses were somewhat stable‚ which resulted in the OPM ratios following a similar trend as the GPM

- Politeness formulas in Arabic: When talking about politeness formulas in Arabic and in English and how they are different‚ it is crucial to take into account the distinction between propositional content of a formula and its illocutionary force potential. A good example showing the relationship between semantic content or propositional content and illocutionary force illustrates in using congratulations in English and “shukran” in Arabic which is equivalent to “thanks”. Sometimes illocutionary
