VAN DE GRAAFF GENERATOR This is a machine that can build up high voltages of the order of a few million volts. The resulting large electric fields are used to accelerate charged particles (electrons, protons, ions) to high energies needed for experiments to probe the small scale structure of matter. Principle 1. Skin effect 2….

2. 1 Motors use the effect of forces on current-carrying conductors in magnetic fields 2. 1. 1 The motor effect The motor effect is where a force acts on a current-carrying conductor in a magnetic field. The right hand palm rule is used to find certain properties: fingers point to magnetic field, thumb points in…

The claw or the formation of making one with your hands is an amazing tool to help get a grip of an object or prey, or even to break something to get the materials inside. Humans even use this technique by using their index finger and thumb at a very young age to show affection…

Introduction             Electroplating can be defined as the deposition of a metallic coating through the subjection of an object with a negative charge to a solution containing a salt containing positive metal ions. Under the influence of an electric charge, the positive ions are attracted to the negatively charged object where they are reduced hence…

Experiment 5: RC Circuits Abstract The purpose of this lab is to learn and understand RC Circuits. An RC circuit is composed of at least one resistor and at least one capacitor. A capacitor is composed of two plates with either air or an insulator also known as a dielectric between the plates. We do…

Introduction: The purpose of this article is to criticize Kurt Lewin’s model of change. I will shows how successful change can be encouraged and facilitated for long-term success. The article compares the characteristics of Lewin’s Three-Step Change Theory. According to me Kurt Lewin’s theory is agoal and plan oriented because it only consider about change…

Introduction Statics is a branch of Mechanics that studies the forces and their effects in rigid bodies in balance. Just like humans, objects and buildings need a skeleton too. This is known as the structure. Bridges, amusement parks, chairs, and many other objects that surround us, have structures, if they didn’t they wouldn’t be able…
