** Atom and Introduction to Nuclear physics ** Introduction Alpha-particle scattering 2.1 Experimental set-up ➢ Alpha particle o is a high-energy helium nucleus with 2 protons and 2 neutrons. o has 2 positive charges. ➢ Gold foil was chosen since it has a high atomic mass. Thin gold foil‚ ~10-6m was bombarded by high-energy alpha particles. ➢ Angular deflections/ scattering of alpha particles were measured by observing

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;

There is a first time for everything. Some first time experiences aren’t so important while others we will never forget. One first time experience I will never forget is the first time I went skiing. I remember being lifted on the ski lift chair. The memory of being on top of the high hill with the feeling I am going to puke will be with me forever. The most memorable moment of this whole experience will be the first time I went speeding down the hill and thinking I am going to hit a tree and die

PHYSICS II ELECTRICITY‚ MAGNETISM‚ SOUND‚ AND LIGHT SERIES CIRCUIT In this unit you’ll begin learning how to analyze circuits. Circuit analysis means looking at a schematic diagram for a circuit and computing the voltage‚ current‚ or power for any component in that circuit. Closely related to the task of circuit analysis is the task of troubleshooting‚ which means figuring out what is wrong in a circuit that is not working correctly. Analyzing and troubleshooting go hand in hand; when a circuit

blanketed by two and a half feet of snow. It was a mild Sunday in early February and I had been on a pair of skis all morning. I had progressed fast enough throughout the day that I had built up a false sense of confidence‚ as it was only my first day of skiing. Confidence that was short lived when faced with the biggest challenge yet‚ an intermediate level ski run that required a controlled precision I had not yet developed. Down the slope I went quickly accelerating to a blaring speed‚ I rounded the first

know why I have never read a book about skiing before there is not much to it but going up and down mountains. That’s not much of a fun book now is it? Wait! Don’t stop reading yet it gets better. As the story begins the motive behind Steff’s journey is to prove she is just as worthy as any “man” mainly her father who she inspires to impress including obtaining his approval. I found the writing a bit philosophical the book’s main focus goes beyond just skiing to what Steph was learning about herself

Experiment 9: THE TANGENT GALVANOMETER; PURPOSE: In this experiment we will measure the magnitude of the horizontal component of the Earth’s Magnetic field by the use of an instrument called a tangent galvanometer. INTRODUCTION: A tangent galvanometer consists of a number of turns of copper wire wound on a hoop. At the center of the hoop a compass is mounted. When a direct current flows through the wires‚ a magnetic field is induced in the space surrounding the loops of

Nordic skiing has changed my life. When I was young I did not think I was capable of performing in such an intense sport. I saw women with such strength and power‚ gliding effortlessly across the snow. I wanted to be like them‚ but I lacked the confidence‚ and I was hesitant to leave my comfort zone. I wanted to stay in a corner of the world where there was no pressure and nothing was expected of me. I joined BSF when I finally realized that I would only feel pressure if I put it upon myself. Since
