Figure 2: Standard curve of Average light absorbance by ten different concentration of Methlene Blue. The data is collected from all the groups in the class. All the points in the graph represent the means of all the groups. The figure shows a direct proportion. Its equation for trend line is Y = 23

Model A The very first differential equation that one typically encounters is the equation that models the change of a population as being proportional to the number of individuals in the population. In symbols‚ if P(t) represents the number of individuals in a population at time ‚ then the so called called exponential growth model is: Recall that the general solution of this differential equation is . Recall also that in order to

trials of the reaction were run at different temperatures (over a range of 40.5 ºC) maintaining the reactants concentration constant‚ and the Activation Energy was determined by means of the graphical analysis of the linearized for of the Arrhenius equation. The Activation energy was estimated to be 74kJmol-1‚ which represents a 9.9% error with respected to the accepted value of 82kjmol-1. | Introduction: Chemical reactions are omnipresent.

Metathesis Reactions and Net Ionic Equations Introduction: Metathesis or double decomposition reactions are a reaction in which two compounds react to form two new compounds‚ with no changes in oxidation number. The ions of two compounds exchange partners. AX + BY AY + BX This reaction can occur between two inorganic salts when one product is insoluble in water‚ driving the reaction forward. A typical example is as followed and is considered a molecular equation. BaCl2(aq) + 2AgNO3(aq)

5 Business Entity Concept- The business and the businessman are two different and distinct entities. I.e. that the firm and the partners‚ the company and the shareholders‚ the owners and the organization have their own distinct identities. All accounting is done from the perspective of the business. The accountant regards owners‚ creditors‚ suppliers‚ customers as parties transacting with the business. All transactions are viewed from the point of view of the business. Money Measurement

Study the graph and write an equation to fit the line. Pretend the triangle region is shaded in and change the equation to an inequality describing this region. The diagram is showing the sofas on the x axis and the recliners on the y axis. There are two points on the graph‚ (275‚ 0) and (0‚ 125)‚ so we can compute the slope of this line. The slope is Running Header: TWO-VARIABLE 3 The point-slope form of a linear equation to write the equation itself can now be used. These are

the mechanical side and spring action provided by the synchronous tie wherein power transfer is proportional to sin d or d (for small d; d being the relative internal angle of machines). 3. Because of power transfer being proportional to sin d‚ the equation determining system dynamics is nonlinear for disturbances causing large variations in angle d. Stability phenomenon peculiar to non-linear systems as distinguished from linear systems is therefore exhibited by power systems (stable up to a certain
