Linear equation

A rate law is an equation used to determine how much the concentrations of solutions will change as times goes on. In this experiment, the rate changed based on the five degree Celsius temperature change and concentration change in three different reactions. In this lab,…

The rate at which a reaction occurs, referred to as reaction rate, is a type of reaction property that directly measures the extent of a reaction. Changes in concentration affect reaction rates in chemical formulas, and if the reaction is not specifically known, the rate cannot be determined. The rates are given in negative or positive measurements depending on whether the concentration is a reactant or product. Knowing this, the first step in finding the reaction rate would be to determine the…

root is a complex number? Answer: If the equation is 7th degree then it has 7 roots. Those roots can be complex or real. Complex roots always come in pairs, so if it has one, then it has 2, the other one being the conjugate of the first one. This in other words, if one complex root is a + bi, then the other complex root is a – bi. If at least one root were complex, then we would have a minimum of 2 complex roots with a maximum of 5 real roots. The equation can have at most 6 complex roots (3…

Introduction This extended experimental investigation (EEI) investigated the effect in which concentration had on the rate of reaction. The purpose of this experiment is to test different concentrations of hydrochloric acid with sodium thiosulfate and to see how long it would take until the cross underneath the flask is no longer visible through the milky white solution. Collision theory A collision is when two or more object run into each other. But collision theory is, that only some…

To give an another definition of complex number, we have to show z= ew for w, where z is any non-zero complex number. If we assume w = u + iv then eueiv = |z|e^i arg z and this means that |z| = e^u , v = arg z . The equation |z| = e^u is a real equation, so we can write u = ln |z|, where ln |z| is the ordinary logarithm with positive real numbers. Hence, w = u + iv = ln |z| + i arg z = ln |z| + i(Arg z + 2n) , n = 0 , ±1 , ±2 , ±3 , . . .6 We profoundly examined the connection between…

Questions: (a) Show that: (b) What value of ε ss would you expect at 800°C and 16000 psi? A= 0.0043 Using your Larson-Miller curve, what temperature should you use for a life of 20 years at the lowest stress level? For the extensive length of time, a temperature of approximately 25 oC which is close to room temperature. With increasing stress or temperature, what changes will you notice in a typical creep curve? When you increase temperature or stress, the creep curve will increase in…

This paper will study the relationship between a country’s perceived amount of corruption, and how that affects the wages of its domestic workers. The premise behind this paper is that a country that is perceived as being dishonest and corrupt would have lower wages. Corruption in government is seemingly always present in our world. This paper will try to determine if there is a correlation between a country’s perceived corruption and the monthly disposable income its workers earn with…

Variance Decomposition Analysis The variance decomposition analysis has applied to quantify the extent up to which the selected indices one influenced by each other. We can also examine the short run dynamic relationship by variance decomposition. While impulse response functions trace the effects of a shock to one endogenous variable in the VAR, variance decomposition separates the variation in an endogenous variable in to the component shocks to the VAR. Thus, the variance decomposition…

I can see that there appears to be a clear linear trend with a positive relationship. Therefore, it would be sensible to use a linear regression model to investigate the relationship. This shows that as the height of the saplings increases, so does the diameter of the saplings at breast height. The rate of increase is not consistent, and the spread of the data increases as the podocarp height does. An interesting point to note…

FastCat Compensation Case Phase 2: External Competitiveness Presented to Oliver Stoutner, M.B.A. HR Practicum I: Compensation and Benefits MGT 4250-01 Presented By Morgan Tullis Kimberly Bowers Ashlie Hawes Travis Stone Rachel Kipling Step 1: Recommend Strategy for Competitiveness When determining a compensation strategy for FastCat, we decided the best option would be to have a job-based structure. The reason for this is that we want to focus on our internal pay structure and measure them…
