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

The investigation on the average mass of DNA with the mass of banana‚ strawberry and kiwi. Purpose: The purpose of this lab is to investigate the comparison between the amount of DNA per gram of fruit that can be extracted from a banana‚ strawberry and kiwi and to determine which one has more DNA. Hypothesis: The banana genome contains 837 MBPs and the strawberry genome contains 206 MBPs and the kiwi genome contains 128 MBPs. This states that there are more base pairs in a banana genome

esterification reaction that was carried out in this lab is shown in figure 1. It worth mentioning that the by-product of such reaction is water. In organic chemistry‚ the reaction in which water molecule is released is known as condensation reaction (Hornback‚ 2006). Figure1 is drawn using Chem Sketch software. a) b) Figure 1: Typical Fischer esterification reaction (a) in comparison to the specific esterification reaction used in this lab (b) The reaction can also be categorized in terms of

cheese. Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist the further understanding of the gene on LAB be giving different stress

Introduction Chemical kinetics is the study of reaction rates. A reaction rate is the speed of the change in either reactants or products over a period of time. General kinetic rate equation is: Where [A] and [B] are the concentration of the species in the reaction. The variable k is the rate constant‚ which is a function of time and catalyst presence. The variables m and n are the order of reaction for their respective species concentration. The higher the value of the reaction order the

In this lab we are going to be observing the decomposition of piglets over a month’s time. There are theory questions that have been given to us before and after the lab. We look back at our original theory to see where we went wrong‚ and then correct it. The lab was disgusting‚ surprising‚ and very interesting. The first questioned to be answered is which piglet decomposes faster‚ a piglet that is in its natural state‚ that is burnt‚ that is buried‚ and that is buried in a wooden box? With
