of thousands of people that used them. The weeks in my first year of high school sped past as I balanced the workloads of my online and school courses. Calculus and Mechanical Physics confronted me one semester; in another, I tackled Differential Equations and Computer Security. Completing these courses not only gave me the knowledge that I had craved, it also exposed me to mindsets of people across the globe. As we worked side by side to tackle difficult problems or finish group projects, I…

This movie has begun in Princeton University on September 1947. It starts with a class of guys listening to a professor on how each of the guys in the class was awarded a scholar ship to study in Princeton. Then there comes a guy name John Nash, who is the main character in this movie. From this, it will tell a story about John Nash and will also talk about his disorders in this movie. The group of guys that where in the class are now outside and talking to each other and getting to know with…

Kwong equations are mainly used as they are simple and a temperature-dependent correction is used for EOS constant A. van der Waals Equation van der Waals proposed the first cubic EOS in 1873. The van der Waals EOS gives a simple, qualitatively accurate relation between pressure, temperature, and molar volume. P=RT/(V-b)-a/V^2 where a is “attraction” parameter, b is “repulsion” parameter, and R is universal gas constant. Comparing this equation with the ideal gas law,P= zRT/v, we see that the…

Testing the Validity of the Approach of Using Hydrogen and Helium Emission Spectra with the Rydberg Equation to Determine the Ionization Energy of Helium Michelle Plavnik Department of Chemistry, Emory University, Atlanta, GA, 30322, United States PAGE 2 ABSTRACT: The purpose of this lab is to determine how accurate the Rydberg equation is at modeling helium transitions and finding the ionization energy from those transitions. To accomplish this aim, the spectra of hydrogen and helium were…

intake 2000 calories per day. My dairy food plan recommends that I have 6 ounces of grains, 2.5 cups of vegetables, 2 cups of fruits, 3 cups of dairy, and 5.5 ounces of protein foods. According to the Harris- Benedict Equation to calculate the Resting Energy Expenditure (REE), the equation is: 655+(9.6 x weight in kg) + (1.8 x height in cm) – (4.7 x age in years) 655+(9.6 x 48 kg) + (1.8 x 156 cm) - (4.7 x 21) 655+460.8 + 280.8 -…

The Concept of Happiness Happiness is finding satisfaction in everyday life. There are many factors that, added together, equal happiness. That particular equation is unique to each individual. Many times happiness is sought in material things. Happiness can not be bought, it is free. It can not be touched, but can be felt and it can not be borrowed, it should be owned. Even though there is not a single definition, or formula, for happiness, there are several common factors that most…

Equation of trendline 1 calculation: m= rise/run = 12/15 = 0.8 c= 5.9 y= 0.8x + 5.9 Equation of trendline 2 calculation: m= rise/run = 25/45 = 0.5 c= 17.6 y= 0.5x +17.6 Point of intersection: Equate both trendlines to find point of intersection 0.8x + 5.9 = 0.5x + 17.6 x= 39 Since x=39, x2= 9 as x2 represents x in descending order. R2: R2 for trendline 1 = 0.98 Correlation coefficient for trendline 1= 0.96 R2 for trendline 2 = 0.98 Correlation coefficient for trendline 2= -0.99 Ratio…

Examples and Solutions Example 1: Given Equation: MnO4- + S2-  Mn2+ + S0 Balance the equation by using the ion-electron method. Step 1 Oxidation: S2-  S0 Reduction: MnO4-  Mn2+ Divide into two half reactions. Identify the element that is being oxidized and the other being reduced. (Use the entire ion or molecule.) Step 2 Oxidation: S2-  S0 Reduction: MnO4-  Mn2+ Balance all the elements (other than oxygen and hydrogen). Step 3 Oxidation: S2-  S0 Reduction: 8H+ + MnO4- …

The Drake Equation Introduction: The Drake Equation is an elaboration of the Principle of Mediocrity; an expression that determines the probability of the discovery of extraterrestrial life within the entirety of the unknown universe. This equation combines the things science knows and does not know to come to the equivalent of N, if N is the number of intelligent species in the universe that are communicating amongst each other right now. The Principle of Mediocrity is essentially…

The formulas for parametric equations of x(t) and y(t) are; x(t)=Position Point+ V_AB t & y(t)=Position Point+ V_AB t . The formula to determine the distance of two different points is; d_AB=√((x_B-x_A )^2+ (y_B-y_A )^2 ). Additionally, the most important is to note that the value…
