** 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

thought of all the physics that is involved in the game of golf? Golf is a game of precision and the smallest miscalculation could mess up a shot. (Real World Physics 2009) The physics of a proper golf swing is more complicated than you might think. You might think that this game is as simple as swinging a club and hitting the ball. But in fact‚ there is a lot more to it. First of all there is the importance of a good technique of coarse‚ but there is also a lot of interesting physics that goes into

The Law of Conservation of Mass Goals: 1. To identify the parts of a chemical equation. Students need to identify subscripts‚ coefficients‚ reactants‚ products‚ chemical formulas‚ and chemical symbols 2. To appreciate that scientific discoveries are often the result of inquiry. 3. to distinguish between an element‚ a compound‚ and a mixture (and between heterogeneous and homogeneous mixtures) 4. To balance a chemical equation in order to prove that the Law of Conservation of Mass works quantitatively as well as conceptually

Physics 4052 Spring 2004 Y. Kubota K. Wick Project Proposal for Physics 4052 Introduction You must begin to think about a possible experimental project to carry out next semester (Physics 4052). The reason for this is two-fold: first‚ it will introduce you to the process of proposal writing‚ which is an unavoidable and very important part of modern experimentation‚ and second‚ it will enable us to make any necessary plans for procuring equipment. To start you thinking about this process‚

20 THINGS YOU CAN DO TO CONSERVE ENERGY Whenever you save energy‚ you not only save money‚ you also reduce the demand for such fossil fuels as coal‚ oil‚ and natural gas. Less burning of fossil fuels also means lower emissions of carbon dioxide (CO2)‚ the primary contributor to global warming‚ and other pollutants. You do not have to do without to achieve these savings. There is now an energy efficient alternative for almost every kind of appliance or light fixture. That means that consumers

Physics of a Guitar (Rough Draft) The guitar is the most played instrument in the music world. The oldest surviving guitar is thought to be made around 1776 in Italy by Gaetano Vinaccia. Though‚ the guitar looks like a simple instrument to construct or play there is a lot of physics behind the creation of it‚ from the strings to the air inside‚ the anatomy‚ and the sound spectrum. There are three types of guitars that are made: nylon acoustic‚ steel-string‚ and electric. Acoustic guitars produce

WATER CONSERVATION IN CHILE How often do we think about water? By Cristián Bravo Galarce Have you ever wondered how long you can live without drinking water? It is not a difficult question if you know a little bit about yourself. When it is hot‚ you need to drink water; when you eat‚ you need to drink water. However‚ you can live without having a shower; let us make it clear‚ you are going to be the one who is there‚ alone‚ nobody is going to like you but you can survive anyway. Water is the

involves physics. Physics is all around. For instance‚ you may go to Six Flags and do not analyze how physics helps the machines you ride in operate. Have you ever asked yourself how a roller coaster works? Would roller coasters safely run without the knowledge that physics offers us? The answer is no. Roller coasters are driven by physics; it mobilizes and gives its riders amusement through forces such as inertia‚ gravitation‚ and centripetal forces and utilizes different types of energies such as

Plasma Complexity! Plasma is said to a substance similar to gas in which a certain portion of the particles are ionized. The basic premise is that heating a gas dissociates its molecular bonds‚ rendering it into its constituent atoms. Further heating leads ionization‚ turning it into plasma: containing charged particles‚ positive ions and negative electrons. The presence of a non-negligible number of charge carriers makes the plasma electrically conductive so that it responds strongly to electromagnetic

Importance for Wildlife Conservation * Maintains ecological balance & the organisms have their unique positions in food chains‚ food webs which keep ecological balance. * Wild life contributes to the maintenance of material cycles such as carbon and nitrogen cycles. * For improvement and progress in agriculture‚ animal husbandry and fisheries the genes from wild life preserved as gene bank are utilised in breeding programmes. * Wild life provides a number of useful products like food‚ medicine
