conditions for equilibrium are that the net force acting on the object is zero‚ and the net torque acting on the object is zero. Thus‚ the following objectives were emphasized in this experiment: to determine the equilibrant force using the force table and the component method‚ to determine the unknown forces using the first condition and second conditions for equilibrium‚ to locate the centre of gravity of a composite body‚ and to demonstrate rational equilibrium. 2. Theory Equilibrant is equal

Aspartame: What Is It And What Effects Does it Have on Your Body? Aspartame‚ also known Acesulfame Potassium (Hull‚ 2006)‚ is commonly known by brand names NutraSweet‚ Equal‚ Sweet One and Spoonful. Aspartame is found in thousands of foods‚ drinks‚ candy‚ gum‚ vitamins‚ health supplements and even pharmaceuticals. This artificial sweetener is the most popular in the United States‚ is 200 times sweeter than sucrose the accepted standard for sweetness‚ and is also the most dangerous substance

The Stroop Effect Experiment In 1935‚ John Ridley Stroop conducted the original experiments of the stroop effect. The stroop effect is an effect that occurs when individuals attempt to name the color of words that spell out a conflicting color. Stroop reported an interference effect when individuals were asked to report the color of words presented to them. Stroop collected his data by showing his participants a sheet of paper with printed words on it. He then asked his participant’s to name the

wrote Mindstorms and advocated a revolutionary philosophy in which technology was as seen as a fulfilling two major roles in education: (a) a heuristic role in which the presence of the computer was seen as a catalyst of emerging ideas and (b) an instrumental role in which the presence of the computer would carry ideas into a world larger than the research centres where they were incubated. When the Children’s Machine was published‚ Papert (1993) looked back over the decade since Mindstorms and asked

voltages. The main question of the experiment is “how long will someone continue to give shocks to another person if they are told to do so‚ even if they thought they could be seriously hurt?” (Milgram Experiment‚ 2008). Of course to conduct any experiment‚ you need participants. Stanley Milgram had forty subjects which were all males. According to Milgram they were “recruited via mail and a newspaper ad. They thought they were going to participate in an experiment about ‘memory and learning’” (2008)

Lab Report (Effect of concentration on enzyme activity) Biology Noor Alawadhi 11- KC Introduction: An Enzyme is a protein‚ which is capable of starting a chemical reaction‚ which involves the formation or breakage of chemical bonds. A substrate is the surface or material on or from which an organism lives‚ grows‚ or obtains its nourishment. In this case it is hydrogen peroxide. This lab report will be explaining the experiment held to understand the effects of the changes in the amount of

Procedures for Part A: For Activity A‚ we first tested enzyme activity. First‚ we used an H2O2 syringe to transfer 10 mL of H2O2 into an unlabeled 60-mL cup. Then‚ we used a transfer pipet to add one mL of catalase solution into the unlabeled 60-mL cup that we put H2O2 in. After that‚ we observed the solution for one minute. Then we tested the effect of boiling on enzyme activity. First we used a transfer pipet to transfer 4 mL of catalase into a test tube. After that‚ we placed the test tube filled

competitive market receives $12.50 for each unit it produces and faces an average total cost of $10. At the market price of $12.50 per unit‚ the firm’s marginal cost curve crosses the marginal revenue curve at an output level of 1000 units. What is the firm’s current profit? What is likely to occur in this market‚ and why? Total rev | 12500 | Total costs | 10000 | TC=ATC(Q) = 10 ( 1000) = 10000 Profit=TR-TC = 12500 - 10000 = 2500 In this case‚ the profit is positive however for perfectly competitive markets

The effect of enzyme concentration‚ substrate concentration‚ pH‚ and temperature on the enzyme catalase. Introduction: Enzymes are biological catalysts; proteins and RNA. They are required for most biological reactions and they are highly specific. Each enzyme has an active site. The active site is the spot on the enzyme where a substrate fits in. Substrates binds with enzymes through the active site. Enzymes‚ being highly specific‚ only fit with one certain substrate. Enzymes and substrates

Investigating the effect of pH on the activity of the enzyme catalase. Introduction Hydrogen peroxide (H2O2) is a very pale blue liquid which appears colourless in a dilute solution‚ slightly more viscous than water. It is a weak acid. It has strong oxidizing properties and is therefore a powerful bleaching agent that is mostly used for bleaching paper. Catalase is a common enzyme found in all living organisms. Its functions include the conversion of Hydrogen Peroxide‚ a powerful and potentially
