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

Lab Exercise 2.03: Recognizing External Connections Is it possible to plug any cable into the wrong connector? If so‚ which one(s)? What do you think would happen if you plugged something into the wrong connector? Answer- Yes‚ the mouse and keyboard connectors. If they plug into the wrong connector‚ the device will not work.

Stoichiometric Analysis Formal Lab Report I. Purpose- The purpose of this lab is to show stoiciometric reactions and relationships first hand. It also increases our level of understanding about the complicated relationships in chemical reactions and in stoichiometry. II. Introduction- In chemical reactions and formulas there are various relationships between masses of reactants and products. The study of these relationships is called stoichiometry which is derived from the Greek words stoichein

Water Analysis Lab Report Purpose: In this lab we will be testing a number of water samples. These water samples come from various water sources. Each of these water samples will undergo four different tests. The four tests include a pH test‚ a conductivity test‚ a total and phenolphthalein and alkalinity test‚ and a total hardness test. This lab requires comprehension of lab material and techniques learned in prior labs (Kippenhan‚ 2012). Procedure: Each

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

Analysis: In this lab we measured the rate of respiration of germinating mung beans and germinating peas at room temperature and 10 degrees Celsius. The rates of respiration at room temperature were higher than the rates of respiration in cold water. The reaction rate of the germinating peas at room temperature was .0125 ml/min and the reaction rate of the peas at 10 degrees Celsius was .0095 ml/min. The same is true for the germinating mung beans. At room temperature the rate of reaction was .0105

LAB 3: QUALITATIVE ANALYSIS Part 2- ANIONS Sameera Feroz Butt Lab Partner: Ram Soni Thursday January 30‚ 2014 Leilani Morales CHEM1131-02 OBJECTIVE The objective of this experiment was to use qualitative analysis to determine the chemical characteristics of four known anions by systemic confirmatory testing. The chemical characteristics observed were to be used to identify an unknown sample. Sulphuric acid was to be added to a carbonate solution and an effervescent reaction would

Lab 5 The Diffraction Grating Chinua McDonald Objective: To measure the wavelength of light with a diffraction grating. Theory: The two types of diffraction gratings are the transmission and reflection gratings. They are made by ruling on a piece of glass or metal a number of evenly spaced lines with a fine diamond point. Diffraction phenomena can be analyzed in terms of Huygens’ principle‚ according to which every point on the wave front of a wave should be considered as a source

indicated by a very pale pink color. To calculate the molarity of NaOH‚ the following equation was used MNaOH x VNaOH = MKHP x VKHP therefore the molarity was .125 M. INTRODUCTION This lab experiment covers the preparation of standard solution and the acid/base titration. The first part of the lab is to prepare a standard solution of Potassium hydrogen per. A standard solution is a solution of known concentration‚ in which it is prepared using exacting techniques to make sure that the molarity
