IB Friction Lab Write Up 3. The slope of my graph represents the constant value for myu as the Normal Force and the force of friction are constantly changing. 4. The kinetic slope is the biggest by far because it represents the less coefficient of friction it has to overcome to move easier. 5. According to my data table‚ an increase in weight always‚ without fail‚ creates a greater force of friction. 6. An increase in weight does not affect the coefficient of friction by also increasing

Introduction Enzymes are proteins that are involved in all the chemical processes in living things. As they are made of proteins they are affected by pH and temperature. Enzymes are catalysts; they speed up chemical reactions without being changed themselves. Digestive enzymes speed up the breakdown of large food molecules into smaller ones so that the blood can absorb them. Enzymes turn a large starch molecule into thousands of tiny glucose molecules. Enzymes end in ’ase’. There are thousands of

It represents the “backbone” of scientific research‚ as well as a useful method in everyday decision making. The steps involved in the scientific method would include‚ but not be limited to‚ the following: 1. Statement of problem 2. Information gathering on research 3. Formulation of hypothesis/possible

factor given the characteristics of labor-intensive industry. Cultural similarities between India and US includes that they were both British colony‚ hence sharing same language. Not only software programming adopted the English language‚ but also opened up the consulting business model for implementation and future opportunities to expand the market need. Furthermore‚ the lack of infrastructures in India could set back the investment. Such barrier was compensated by the government incentives such as tax

on the filter paper. Caution should be used as the root tips are very fragile 5. Transfer one of the garlic root tips to the clean microscope slide. Cut about 2-3 mm from the rounded growing tip. Keep this growing tip and discard the rest. 6. Break up the root tip with the mounted needle (this is called maceration). Add one small drop of toluidine blue and leave to stain for 2 minutes 7. Cover with the cover slip and blot firmly with several layers of filter/ tissue paper and press gently to spread

a. The beak size of 12 mm is relatively shallow compared to the available range from 10 mm to 30 mm. b. The shallow beak size of 12 mm is not suited for the hard seeds that are available because of the low rainfall of 20 cm. 3. The beak size went up on the islands as time progressed because only hard seeds were available to the finches. Therefore the average beak size increased over time because the trait of larger more deep beaks were more suitable for survival in the given environment. As more

Littlefield Simulation Write-up December 7‚ 2011 Operations Management 502 Team 9 Littlefield Lab We began our analysis by searching for bottlenecks that existed in the current system. It was easily identified that major issues existed in the ordering process. Without calculations‚ you could tell the reorder point was too low since the historical plots showed inventory levels at zero for two or more days at a time. The number of jobs in customer orders showed correlating spikes at the same

The Tegan / Hrad Write-Up SECTION 1: Was outsourcing the A/P project the right move for Tegan given the other possible alternatives? Outsourcing has seemed to acquire a rise in popularity and usage in our modern times. Outsourcing involves entering into a contract in which an in-house company process‚ or processes‚ is ultimately handed over and dealt with from a third party’s perspective. I would have to say that there are three primary‚ helpful factors to outsourcing‚ especially when it comes
