Moment of Inertia and Rotational Motion Garret Hebert PHY 2311 Tues 1:00 garret.hebert@hindscc.edu Abstract: During this lab we will study what rotational Inertia is and how different shapes of masses and different masses behave inertially when compared to each other. We will specifically study the differences of inertia between a disk and a ring. We will use increasing forces to induce angular acceleration of both a disk and a ring of a certain mass. We will then then measure the differences

Outline the main features of experimental social psychology and consider the influences that led to its emergence. What do you think are its strengths and weaknesses? Psychology was originally a branch of Philosopy‚ according to Hollway (2007). As more emphasis was placed on following scientific methods and principles‚ psychologists began using laboratory experiments to carry out research into individual behaviours. Experiments were considered to be more objective when considering individuals

Quasi-Experimental Research vs. True Experiments Unit 9 November 18‚ 2012 Introduction I will compare and contrast quasi-experimental research and true experiments by addressing their weaknesses and strengths. Throughout my project I will give a detailed description of my experimental method used‚ as well as a thorough justification of why I selected this method as well as my sampling plan. I will also identify the target population

In Meghan Daum’s article “Using privilege as a weapon”‚ she tactically begins with insults thrown at her before. She says these insults in a brief and concise way. Furthermore‚ she makes being “an ugly hobbit” or “whore” not have much importance. Daum’s sincere response lets her audience know that she experiences“not-so-nice” insults in the past. Even so‚ insults do not define her nor matter to her. Daum’s main point for resurrecting past insults are not for comedic value‚ but for a bigger issue

affected by changes in pH. The most favorable pH value— the point where the enzyme is most active—is known as the optimum pH. This experiment was conducted to determine the effect of pH reaction rate on an enzyme‚ catalase‚ from yeast. The experimental results indicate that the catalase worked best at a neutral pH level of seven (7). Introduction An enzyme is a protein molecule that serves as a catalyst. “The basic function of an enzyme is to increase the rate of a reaction; most cellular reactions

Enzyme Activity Lab Hypothesis: 1] Are enzymes reusable? Yes‚ enzymes are reusable. 2] Which of the following do you think contain catalase? [Manganese dioxide‚ chicken meat‚ apple‚ carrot‚ potato‚ or chicken liver] I think that the manganese dioxide‚ apple‚ and carrot contain the catalase. 3] Would grinding the materials affect enzyme activity? I think that grinding the materials will increase enzyme activity. 4] Would temperature affect enzyme activity? I think that

determine how different abiotic conditions affect the rate at which enzymes accelerate/cause reactions In this lab students measured the height of the foam after catalysis between catalase (enzyme) and 7 other (solutions) to determine which solution had the fastest reaction rate.. The control variable of the experiment would be the solution of only hydrogen peroxide‚ water‚ and catalase. The independent variables of the experiment were the abiotic factors such as PH level‚ temperature‚ and the amount

Purpose: To find out the densities and to find out the name of the unknown metals. (Based on the extensive and intensive properties) Check up the words mass‚ volume‚ density‚ extensive properties‚ and intensive properties. Where do the units for mass and volume) come from and what do they mean? What is the density of distilled water? What is Archimedes principle? Does temperature affect the density of a solid? Liquid? Gas? Materials: Safety glasses‚ 10‚ 25 or 50 mL graduated cylinders

Experimental Research PSY/285 I have chosen to describe the study to be performed by the pharmaceutical company that wants to test a new sleep aid. Before they engage in human studies the researchers must determine what they want to prove exactly. Since the goal of the drug is to promote better sleep habits‚ the hypothesis for this study would be that individuals taking this new aid will fall asleep faster and stay asleep longer than they did before they started taking the drug

ERROR ANALYSIS Error analysis emerged with the growing criticism of constrictive analysis. It was S.P Corder who first advocated in ELT and Applied linguistics community the importance of errors in language learning process. Corder (1967) mentions the paradigm shift in linguistics from a behaviouristic view of language to a more rationalistic view and claims that in language teaching‚ one noticeable effect is to shift the emphasis away from teaching towards study of learning. Corder further
