Investigation: how the resistance in a circuit varies with the length‚ thickness and type of wire Introduction A current is a flow of negative electrons around a circuit or electrical pathway. This is measured in how many electrons per second or the charge they are carrying go round the circuit (amps or amperes) Voltage or Potential Difference measures how much energy individual electrons have to use up as they go around a circuit. (Volts) Components in a circuit have a Resistance value which will

In 1990‚ the United Nation Education‚ Scientific and Cultural Organization (UNESCO) launched Education For All (EFA)‚ the movement to provide quality education for all children‚ youth‚ and adults globally by the year 2015. The right to education is universal and extends to all children‚ youth and adults with disabilities. This right is enshrined in the Convention on the Rights of the Child (1989) and the

Resistance to change may be categorized into three groups of factors (Mabin‚ Forgeson & Green‚ 2001): organizational‚ group and individual. Organizational factors are caused by threats presented by unknown or unwelcome organizational structure and process change and threats induced by the environment inside or outside of the organization. Group cohesiveness and social norms under threat and participation in decision-making not properly attended would trigger resistance to change. Individual factors

Anthony Young Partner: Nick Dale TA: Alekhya 6/15/15 The SN2 Reaction: Factors Affecting SN2 Reaction. Introduction In the substitution reactions‚ the leaving group from the substrate is replaced with the nucleophile. Because of the nucleophile it is called nucleophilic substitution. The lone pair of electrons‚ present on the nucleophile is used to create a new bond with the carbon atom‚ from which the leaving group was separated. There are two different mechanisms of nucleophilic substitution: SN1

Among factors influencing choice of restaurants are closeness to residence‚ price of food and quality of food were the most important factors 62 (38%). Twenty-seven (28%) eat in restaurants because of the similarity of the food to that of their home country. Of the most preferred food‚

Batteries‚ Resistance and Current “Battery-Resistor”: Check “show battery” and “show cores”‚ watch what happens‚ adjust some variables 1. Why do electrons (blue dots) move? Draw a diagram of the battery‚ label the flow of electrons. The flow of current (+) is opposite; draw this and note if toward or away from + terminal of the battery. The blue dots indicating the electrons move because there is a voltage across the battery in which the electrons flow away from the positive terminal

Factors affecting the movement of water through osmosis Introduction In this I will be investigating what effects the movement of water through osmosis. Osmosis is the diffusion of water. It is the process in which fluids pass through a partially-permeable membrane. It is the movement of water from high water concentration to low water concentration. Plant cells react to osmosis by hypertonic‚ isotonic and hypotonic. Keywords Hypertonic – is when the water outside of the cell is lower than

parents. Death rates were high and life expectancy was low; life expectancy at birth was in the range of twenty to forty years (most likely around thirty years) until the middle of the eighteenth century. This high mortality was a function of several factors‚ including poor nutrition‚ which led directly to deaths through starvation and indirectly through increasing susceptibility to disease; epidemics; and‚ quite possibly‚ infanticide and geronticide‚ especially during times of food shortage.
