complying with your responsibilities under your legal expenses insurance policy ROAD ACCIDENTS: CAUSES‚ CONSEQUENCES AND PREVENTION We are going to discuss the CAUSES‚ CONSEQUENCES and PREVENTION of ROAD ACCIDENTS. Road accidents also called traffic collision are caused by humans when they overlook laid down rules and regulations governing the use of roads. According to the population reference Bureau “an estimated 1.2 million people are killed in road crashes each year and as many as 50 million are injured”

MEDIUM ACCESS CONTROL PERFORMANCE IN SATELLITE COMMUNICATION ABSTRACT MAC protocols are designed to coordinate the transmission of packets‚ retransmission of damaged packets‚ and resolution of collisions among stations during a contention period . The MAC protocols include fixed assignment protocol‚ demand assignment protocol‚ random access protocol‚ reservation protocol‚ hybrid of reservation protocol and random access protocols and adaptive protocols.

structure of the atom. Exactly seventy years later scientists and engineers at the European Organization for Nuclear Research (CERN) launched the Large Hadron Collider (LHC) which was designed to achieve quite the same purpose as Rutherford’s‚ particle collisions. However‚ this time the collider was not a simple particle emitter set up on a laboratory table but a circular tunnel of a 17 mile circumference that spread under villages and cow pastures of the French-Swiss border. Built with the collaboration

Chapter 9 IMPULSE AND MOMENTUM COLLISION PROBLEMS A tennis ball and racket collision: a microscopic view COLLISION: FORCE VS TIME GRAPH A large force exerted during a small interval of time is called an impulsive force. LINEAR MOMENTUM The product of the particle’s mass and velocity is called the linear momentum p = mv As a vector quantity‚ the momentum can be represented in terms of its components: px= mvx py= mvy ALTERNATIVE FORM OF NEWTON’S SECOND LAW F = ma = m(dv/dt) =

INTRODUCTION During collisions involving two bodies‚ equal and opposite forces are set up between them. These impact forces influence the subsequent motion of the bodies. Momentum of the system (consisting of both bodies) is preserved if both bodies are free to move in space. This is because there is no external forces act on the system. The forces acting between the bodies during the small interval of time when they are in contact cause changes in the velocities of each separate body. An

greater than one another. Collision model provides characteristics of chemical reaction. Molecules must collide in order to react; and Characteristics such as higher concentrations‚ high temperature‚ etc. plays the role of increasing the speed of reaction or having more collisions. Scientists use collision model to understand why some molecules react and some do not. Also see how strong collision can break the bond of molecules to produce the product. molecules collision needs energy to break bonds

According to collision theory‚ should the surface area increase the amount of collisions increase increasing the rate of reaction. Therefore‚ my hypothesis is that when the surface area increases the rate of reaction increases. Background information: “Collision theory is a theory proposed independently by Max Trautzin 1916 and William Lewis in 1918‚ that qualitatively explains how chemical reactions occur and why reaction rates differ for different reactions. The collision theory states

affect the reaction. The collision theory explains that in order for a reaction to occur‚ reacting particles must collide with one another. An effective collision makes reactants result in a reaction and for to be successful two things must happen‚ the correct orientation of reactants‚ and the sufficient collision energy. The orientation of reactants explains that reacting particles must collide with the proper orientation relative to one another‚ for sufficient collision energy‚ it explains that
