Physics GCSE coursework: Resistance of wire Aim: To investigate if the length of wire affects its resistance. Prediction (Hypothesis): I predict that the longer the wire the higher the resistance‚ and the shorter the wire the lower the resistance. Knowledge: Resistance is that property of electric components that turn electric energy into heat in opposing the passing of an electric current.It can be beneficial‚ as in electric heaters‚ or a pest‚ as in light bulbs‚ where the heat

Wind the wire around the PVC pipe. Fix the ends of the wires to the insulation tape. Remove about 3 cm. of insulation from the wire using the tips of the paper knife. Measure the resistance of the wire using the ohm setting on the multimeter

WHAT ARE THE MICRO AND MACRO ENVIRONMENT AFFECTING MARKETING INTRODUCTION A Business principally is the organized effort by individuals in an organization to produce goods and services and to sell these goods and services in a market place to earn a good profit margin. The operating environment for all organizations whether they are commercial‚ charitable‚ governmental‚ or in the public sector more generally‚ is never static and seldom entirely predictable‚ and can therefore profoundly affect a

Factors Affecting Climate There are many different factors that affect climate around the world. The most important factors are:- • Distance From The Sea • Ocean Currents • Direction of Prevailing Winds • Relief • Proximity To The Equator • The El Nino Phenomenon • Recently‚ it has been accepted that human activity is also affecting climate. Distance From The Sea (Continentality) The sea affects the climate of a place. Coastal areas are cooler and wetter than inland areas

carefully. * I am going to only use a maximum voltage of 2 volts. * I will be careful when handling the mains equipment. * I will make sure I have a clear space to work in and nothing on the floor around me. In this investigation‚ I will set up a simple circuit to be able to read the voltage and current when the length of wire changes‚ so I then can work out the resistance. I will be using constantan wire starting of with 1m length and then decreasing it by 0.10m intervals down to 0.20m long. I will not

Riccardo Pelizzo Comparative Government 21 April 2003 Factors affecting Democratization The Third Wave of Democratization‚ written by Samuel P. Huntington‚ analyzes global political development of the late twentieth century. He examines the factors that induce a country to undergo the transition from a non-democratic form of government to a democratic form of government. He claims that there have been three waves of democratization‚ and his book particularly focuses on the third wave which

Factors Affecting Photosynthesis Low light intensity lowers the rate of photosynthesis. As the intensity is increased the rate also increases. However‚ after reaching an intensity of 10‚000 lux (lux is the unit for measuring light intensity) there is no effect on the rate. Very high intensity may‚ in fact‚ slow down the rate as it bleaches the chlorophyll. Normal sunlight (usually with an intensity of about 100‚000 lux) is quite sufficient for a normal rate of photosynthesis. Open and Closed

Factors Affecting Diffusion How does temperature affect diffusion? What is Diffusion? Definition 1: Diffusion is a process where by molecules move from an area of high concentration area to an area of low concentration. Definition 2: Diffusion is an evidence for moving particles. The spreading out of a gas is called diffusion and it takes place in haphazard and random way. Gases diffuse because the particles collide with other particles and bounce of in all directions. For example when

Analyse the relationships between the factors and explain how they can impact on wellbeing. In Maslow’s hierarchy to reach self-actualisation‚ which is at the top‚ you must go through; the physiological needs‚ safety needs‚ social needs‚ esteem needs to then finally reach the top and these all affect your wellbeing. The factors affecting wellbeing are physical‚ emotional‚ economic‚ social‚ spiritual and cultural. These 6 factors contribute to the quality of people’s lives and affect a person’s
