Nuclear Power Stations 8.4.1: The firing of neutron at a heavy nucleus may result in the nucleus splitting‚ releasing free neutrons and lighter nuclei; which can then collide with other nuclei and resulting in the same process. This is a fission chain reaction. 8.4.2: In a fission reaction‚ if you can remove the emitted neutrons from the fissionable material‚ then you can control the rate at which the chain reaction proceeds. A fission reaction whereby the reaction is allowed to proceed without

How should schools prepare children for a globalizing world? The world is changing. As I write this paper there are wars and peace treaties being made‚ children being born and people dying‚ new technologies shared and old technologies lost. The world is changing faster than ever before. The schools of today should be preparing students for the problems of tomorrow. Schools of today should be packed with computers and technology letting children learn in a more modern way. Children should

Errors in Attribution It is human nature for us to think about other people’s actions and intentions and then process what they mean. In this way‚ we form attributions‚ which help us understand others’ purposes and objectives. There are two main types of attributions. The first is dispositional attribution‚ which are assumptions that are made based on someone’s behaviour where a person assumes the behaviour is caused by someone’s personality or character. The second type is a situational attribution

The Chronicle of a Death Foretold by Gabriel Garcia Marquez explores a story through Columbia‚ published in 1981. Colombia’s society revolved around family morals‚ cultural values and religious beliefs. The top priority in society was respecting the idea of ‘honor’‚ which Marquez displays as being immoral. The novella deals with themes based on religion‚ culture and sacrifice. One of the many interesting aspects in the novella is the usage of time. The title of the novella dictates to be a ‘chronicle’

Chemistry Internal Assessment: Determining the Enthalpy Change of a Displacement Reaction AIM: To determine the enthalpy change for the reaction between copper(II) sulfate and zinc. BACKGROUND THEORY: Bond breaking is endothermic while bond forming is exothermic. The reaction between copper(ll) sulfate and zinc is exothermic as the energy required to form the bonds of the products is greater than the energy required to break the bonds of the reactants. In an exothermic reaction‚ heat is

Scarcity -Basic Economic problem - unlimited wants‚ but limited resources The question is: How do we allocate these limited resources? 3 questions that any economic system must answer: - What should be produced - How should we produce it? - Who gets it? Command Economy - You have heavy state involvement - State of ownership of resources and control of production - What should be produced - the state decides - How to produce it - the state decides - Who gets it - the state decides Market
