The Atwood Machine Lab

Objective The objective of this experiment is to study Newton’s Second law of motion utilizing the Atwood Machine and to show that the acceleration is proportional to the force causing the motion. Theory Newton’s second law of motion states that the acceleration of an object is directly proportional to the net force acting on the […]

Weapons of Mass Deception: the Uses of Propaganda in Bush’s War on Iraq

Weapons of Mass Deception: The Uses of Propaganda in Bush’s War on Iraq – By Sheldon Rampton and John Stauber As the Bush Administration’s rationales for going to war with Iraq continue to unravel, questions are ‘finally’ being asked about how they got into the mess in the first place. How could an invasion of […]

Determination of the Molar Mass of a Dibasic Acid

A dibasic acid is one in which there are two hydrogen atoms which can be donated as protons (H+):- If a solution of this dibasic acid is titrated with a standard base, the concentration of the acid solution can be determined and ultimately so can the molar mass. PROCEDURE APPARATUS * Weighing scales * Weighing […]

Hydrated Iron 2 (ii) Sulphate Formula

Hydrated FeSO4 can come in many hydrated forms. Using two methods for better accuracy and to make a comparison, I will deduce the number of water molecules per mole of a hydrated iron(II) sulphate sample.Method 1: FeSO4. nH2O(s) � FeSO4(s) + nH2O(l) =dehydrating the FeSO4 by evaporating the water and calculating the mass lost. Hazards […]

Charge to Mass Ratio of the Electron

Charge to Mass Ratio of the Electron Thomas Markovich and John Mazzou Departments of Physics University of Houston Houston, TX 77204-5006 (Dated: September 23, 2010) We sought to reproduce the experiment ? rst preformed by KT Bainbridge to determine the charge to mass ratio of the electron. In this paper, we derived the relationship between […]
