cathodic peak current reveals diffusion controlled reduction. Moreover‚ the electroactive area can be estimated by Randles- Sevcik equation [2] for the modified electrode. The diffusion coefficient of enzymatically oxidized dopamine was obtained from slope of the straight line obtained in the plot Ipc versus υ1/2 (Fig. 4.3.4.1b). The electroactive area of the prepared electrode is calculated by equation [2] and it is 0.0396

Chemistry 1061: Principles of Chemistry I Gas Laws Gas Laws: Pressure‚ Volume‚ and Temperature Introduction Pressure‚ volume‚ and temperature are properties of gases that reveal their relationships when any one of them is varied. Changing the temperature of a gas may change its volume or pressure‚ but how? What are the mathematical relationships between these properties? Are there limits to them? Scientists have discovered through the study of properties of gases that there is indeed a theoretical

the period of the regression? The intercept is 0.0113. Since I calculate the excess return of Boeing and S&P 500 (the return of Boeing minus Rf‚ the return of S&P500 minus Rf)‚ I compare the intercept with 0. The intercept suggest that Boeing’s stock performed 1.13% better than expected. What is the slope of the regression? -What does it tell you about the risk of the stock? The slope of the regression is beta. Beta is a measure of the systematic risk. The slope is greater than 1. When the market

Calculation of compound lenses of A and B The relationship of the focal length is given by equation 5 and using the focal length found in Part I Rearranging the formula and isolating for fc: fc = (f1f2)/(f1 + f2) (equation 7) fc = (11.1cm*11.6cm)/(11.1cm + 11.6cm) fc = 5.67cm The theoretical focal length for the converging lens A and B was 5.67cm. %difference between the theoretical value and experiment

the opportunity to be actively involved in math through data analysis and statistics that are integrated into the curriculum. My hope is to show that these types of activities can be incorporated into an algebra I course as a way of teaching slope‚ y-intercept‚ and linear equations. I plan to teach a unit on linear equations during the third nine weeks of an eighth grade algebra I course next semester. The project will begin with one class learning the material typically covered in most algebra

In an EPS-EBI graphical relationship‚ the slope of the debt ray is steeper than the equity ray. The debt ray has a lower intercept because: A) more shares are outstanding for the same level of EBI. B) the break-even point is higher with debt. C) a fixed interest charge must be paid even at low earnings. D) the amount of interest per share has only a positive effect on the intercept. E) the higher the interest rate the greater the slope. 2. A firm has zero debt in its capital
