It also provides other services to its employees such as hospitals and several fire stations that serve both the company and its surrounding residential areas. The company has employed various forms of telecommunication such as the use of emergency telephone help lines in order to cater for the safety of its workers, the public and even the environment in case of a disaster (Comer 2006). In maximizing the extraction and use of oil and gas, the company has integrated detailed electronic and human networks. A well established fiber optic technology system that supports high bandwidth voice and data communications has been set up enabling authorities to monitor performance of sea operations from land. It also operates a radio mobile network for its operational areas. A detailed company website is also another means by which the company is able to advertise its products and services to the entire world. This lessens time and distance barriers enabling the company to survive in the current competitive marketplace. In regard to the rapidly changing technological environment, ABC communications would like to offer a proposal for the assessment of in-place telecommunication equipment to determine whether they are effective, efficient and economical. This will ensure that the company is up to date with the current telecommunication advancements as it involves analyzing the future viability of the current systems in place while scrutinizing their impact on the achievement of organizational goals. Achievement of the above will entail the following:Advertising Looking for report on communications media? Let's see if we can help you!

The Physics of a Car Collision

The Physics of a Car Collision During a car crash, energy is transferred from the vehicle to whatever it hits, be it another vehicle or a stationary object. This transfer of energy, depending on variables that alter states of motion, can cause injuries and damage cars and property. The object that was struck will either absorb the energy thrust upon it or possibly transfer that energy back to the vehicle that struck it. Focusing on the distinction between  force  and  energy  can help explain the physics involved. Force: Colliding With a Wall Car crashes are clear examples of how Newtons Laws of Motion work. His first law of motion, also referred to as the law of inertia, asserts that an object in motion will stay in motion unless an external force acts upon it. Conversely, if an object is at rest, it will remain at rest until an unbalanced force acts upon it.   Consider a situation in which car A collides with a static, unbreakable wall. The situation begins with car A traveling at a velocity (v) and, upon colliding with the wall, ending with a velocity of 0. The force of this situation is defined by Newtons second law of motion, which uses the equation of force equals mass times acceleration. In this case, the acceleration is (v - 0)/t, where t is whatever time it takes car A to come to a stop. The car exerts this force in the direction of the wall, but the wall, which is static and unbreakable, exerts an equal force back on the car, per Newtons third law of motion. This equal force is what causes cars to accordion up during collisions. Its important to note that this is an idealized model. In the case of car A, if it slams into the wall and comes to an immediate stop, that would be a perfectly inelastic collision. Since the wall doesnt break or move at all, the full force of the car into the wall has to go somewhere. Either the wall is so massive that it accelerates, or moves an imperceptible amount, or it doesnt move at all, in which case the force of the collision acts on the car and the entire planet, the latter of which is, obviously, so massive that the effects are negligible. Force: Colliding With a Car In a situation where car B collides with car C, we have different force considerations. Assuming that car B and car C are complete mirrors of each other (again, this is a highly idealized situation), they would collide with each other going at precisely the same speed but in opposite directions. From conservation of momentum, we know that they must both come to rest. The mass is the same, therefore, the force experienced by car B and car C is identical, and also identical to that acting on the car in case A in the previous example. This explains the force of the collision, but there is a second part of the question: the energy within the collision. Energy Force is a vector quantity while kinetic energy is a scalar quantity, calculated with the formula K 0.5mv2. In the second situation above, each car has kinetic energy K directly before the collision. At the end of the collision, both cars are at rest, and the total kinetic energy of the system is 0. Since these are inelastic collisions, the kinetic energy is not conserved, but total energy is always conserved, so the kinetic energy lost in the collision has to convert into some other form, such as heat, sound, etc. In the first example where only one car is moving, the energy released during the collision is K. In the second example, however, two are cars moving, so the total energy released during the collision is 2K. So the crash in case B is clearly more energetic than the case A crash. From Cars to Particles Consider the major differences between the two situations. At the quantum level of particles, energy and matter can basically swap between states. The physics of a car collision will never, no matter how energetic, emit a completely new car. The car would experience exactly the same force in both cases. The only force that acts on the car is the sudden deceleration from v to 0 velocity in a brief period of time, due to the collision with another object. However, when viewing the total system, the collision in the situation with two cars releases twice as much energy as the collision with a wall. Its louder, hotter, and likely messier. In all likelihood, the cars have fused into each other, pieces flying off in random directions. This is why physicists accelerate particles in a collider to study high-energy physics. The act of colliding two beams of particles is useful because in particle collisions you dont really care about the force of the particles (which you never really measure); you care instead about the energy of the particles. A particle accelerator speeds up particles but does so with a very real speed limitation dictated by the speed of light barrier from Einsteins theory of relativity. To squeeze some extra energy out of the collisions, instead of colliding a beam of near-light-speed particles with a stationary object, its better to collide it with another beam of near-light-speed particles going the opposite direction. From the particles standpoint, they dont so much shatter more, but when the two particles collide, more energy is released. In collisions of particles, this energy can take the form of other particles, and the more energy you pull out of the collision, the more exotic the particles are.
