** Atom and Introduction to Nuclear physics ** Introduction Alpha-particle scattering 2.1 Experimental set-up ➢ Alpha particle o is a high-energy helium nucleus with 2 protons and 2 neutrons. o has 2 positive charges. ➢ Gold foil was chosen since it has a high atomic mass. Thin gold foil‚ ~10-6m was bombarded by high-energy alpha particles. ➢ Angular deflections/ scattering of alpha particles were measured by observing

Identity is never static. “No man is an island‚ entire of itself”‚ English poet John Donne once wrote. Nearly four hundred years later‚ in 21st century’s modern society‚ the emotional attachments between individuals have grown even more immense than it ever was. Complemented by the pace of today’s society‚ this complex relationship is further developed. While being influenced by others‚ we undergo psychological changes‚ which will manifest in amendments in

(Chemical Equilibrium) 1. Write the equilibrium constant expression‚ Kc‚ for each of the following reactions: a) 2NO(g) + O2(g) ⇄ 2NO2(g) b) The decomposition of solid potassium chlorate to solid potassium chloride and oxygen gas. c) 4HCl(g) + O2(g) ⇄ 2H2O(g) + 2Cl2(g) d) 2NO2(g) + 7H2(g) ⇄ 4H2O(l) + 2NH3(g) e) H2O(g) + C(s) ⇄ CO(g) + H2(g) f) The reduction of solid copper (II) oxide with hydrogen gas to produce copper metal and water at 500oC. 2.

Understanding Equilibrium in the IS/LM Model 1995 version Prof. Humberto Barreto1 Introduction: This brief work is designed to provide additional ammunition for the student in the ongoing war against IS/LM confusion and ignorance. The author has claimed in his Notes on Macroeconomic Theory (1995) that‚ There should be no mystery or uncertainty surrounding the IS/LM analysis at this point. IS/LM curves are simply a short-cut to finding the equilibrium values for income and interest rate. There

Regents Physics Constant Velocity/ Acceleration Lab 10-3-13 Problem: Graphical Analysis of Constant Velocity and Accelerated Motion. Theory: Gravitational acceleration is constant on Earth g=9.8m/s2 Therefore‚ when the golf ball is dropped‚ the acceleration will be equal to gravitational acceleration agb=9.8m/s2 Given there is no air resistance‚ this means that when the golf ball is dropped from a given distance‚ according to the formulas‚ the golf ball will accelerate

demonstrates the main aspects behind causing inequality between male and female rights in the Arab World. Colp Rubin clearly states based on certified statistical evidence‚ that despite of the basic rights given to females in the Arab region‚ lack in the equilibrium between both genders has still been consistent. She demonstrates her claim by referring to the discriminated political roles given to women in government‚ to the violence and mistreatment caused by peers in the surrounding society‚ and finally in

CHEMICAL EQUILIBRIUM I. Introduction In a chemical reaction‚ when reactants are mixed together in a reaction vessel‚ the whole of the reactants do not get converted into products. After some time‚ there will come a point when a fixed amount of reactants will exist in harmony with a fixed amount of products; neither amount will change anymore. This state is called chemical equilibrium (Birk‚ 1994; Jones‚ 1987; LeMay‚ 2002). There are three characteristics of a system in chemical equilibrium: a. the

Difference between Static and Dynamic RAM The journey of dynamic and static RAM was initiated in 1960s which was readily developed in 1970s. In recent days‚ the technology is much more user friendly. RAM is classified into two types: Dynamic RAM and Static RAM. Static RAM uses a form of flip-flop to circulate data. It uses almost six transistors for its functioning. On the other hand‚ Dynamic RAM (DRAM) is typically charged on the capacitor in it. Static RAM holds the data in the

Equilibrium and Acid Base Test Review: May 2012 Things to know: 1. Explain DYNAMIC EQUILIBRIUM. Why does a reaction at equilibrium look like it is NOT reacting? 2. Are all reactions equilibrium reactions? What assumptions do we make when we say that a reaction does NOT take place or that it is UNIDIRECTIONAL and goes 100% to completion 3. Be able to sketch a graph of the following (assuming that you start with all reactants and no products) : a. A reaction that really doesn’t do anything
