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

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

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

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

tries to regain its initial size‚ hence applies a counter force on the load‚ which is called the restoring force of the spring (Ahmad‚ Z etc‚ 2007). When a mass is suspended from a spring and the system is allowed to reach equilibrium‚ Newton’s Second Law tells us that the magnitude of the spring force equals the weight of the body. Therefore‚ if we know the mass of a

1. What are the spring constant (k) is for spring 1 and spring 2? What are the units of k? Which spring is stiffer? Fs= kx k is the spring constant and it is measured in N/m or in kg•m/s2 Spring constant for Spring 1= .49=k(.01)= 49 k=49 N/m Spring constant for spring 2= .49=k(.02)= 24.5 k=24.5 N/m Spring 1 is stiffer; you can see that by the smaller change in spring length‚ and the higher spring constant. 2.

PHYSICS PROJECT TO STUDY THE OPTICAL LENS OF A HUMAN EYE Eyes are organs that detect light‚ and convert it to electro-chemical impulses in neurons. The simplest photoreceptors in conscious vision connect light to movement. In higher organisms the eye is a complex optical system which collects light from the surrounding environment; regulates its intensity through a diaphragm; focuses it through an adjustable assembly of lenses to form an image; converts this image into a set of electrical signals;
