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

Name: Jayanti Magar Title: Observations of Chemical Changes Date: 02/11/015 Pre Lab Questions: Use what you learned in this lab to answer the following questions. A. Suppose a household product label says it contains sodium hydrogen carbonate (sodium bicarbonate). How would you test this material for the presence of sodium bicarbonate? I would add hydrochloric acid (HCl) with carbon dioxide with NaHCO3‚ and it should bubble and form gas. B. You know what color phenolphthalein and bromothymol

Buffers‚ and pH‚ and Diffusion oh my The pH of a solution is the measure of the concentration of charged Hydrogen ions in that given solution. A solution with a pH lower than seven is considered to be acidic. A solution with a higher pH is a base. It is very important for organisms to maintain a stable pH. Biological molecules such as proteins function only at a certain pH level and any changes in pH can result in them not functioning properly. To maintain these constant pH levels‚ buffer solutions

PRE-LAB The purpose of the lab is to determine the moles of hydrogen gas and then molar mass of the metal. First‚ the metal assigned to each group must be weighed out in order to ensure the hydrogen gas produced will not exceed the capacity for the gas measuring tube. Then‚ copper will be wrapped around the metal leaving 6-8cm at the end for a handle. The end wire will be bent into a hook to keep the sample at the bottom of the tube and increase the oxidation rate. A ring stand will need to be

Virtual Lab Unit 3 1. Briefly describe the steps required to aseptically transfer bacteria from an unknown to a tube of liquid broth. You might have to research this using the "T" button (Tell Me More About...) To aseptically transfer bacteria from an unknown to a tube of liquid broth you have to flame the loop or wire before you begin to sterilize it. You then remove the caps from the tubes and flame the mouths of the tubes to prevent air-borne contamination. When all this is done‚ you have to

sciencebyjones.com/safety_rules.htm Thanks to the Flinn Scientific Safety Rules for much of the below. General Guidelines 1. Conduct yourself in a responsible manner at all times in the laboratory. 2. Be familiar with your lab assignment before you come to lab. Follow all written and verbal instructions carefully. If you do not understand a direction or part of a procedure‚ ask the teacher before proceeding. 3. Never work alone. No student may work in the laboratory without an instructor

Red-Black Tree Abstract--In this paper‚ Red-Black Tree is discussed and various operations that can be performed on it are illustrated. The operations include rotation/restructuring (Left-Rotation and Right-Rotation)‚ inserting a node in Red-Black Tree and deleting a node from Red-Black Tree thereby maintaining its Red-Black Properties. I. Introduction A fascinating and important balanced binary search tree is the red-black tree. Rudolf Bayer invented this important tree structure in 1972
