...acceleration of -2.5 m s–2 because of a red light and comes to rest. It remains at rest for 45.0 s, then accelerates back to a speed of 25 m s–1 at a rate of +2.5 m s–2. How far behind the train is the car when it reaches the speed of 25 m s–1, assuming that the train’s speed has remained constant at 25 m s–1. Solution:- For the car to stop we used the equation v2=v02 + 2as and v = v0 + at m and s For the car to speed up again, m and time taken, s Total distance moved by car in that time = 125 m + 125 m = 250 m. Total distance travelled by the train = 25 × (10+45+10) = 1625 m Therefore the car is (1625 – 250) = 1375 m behind the train. [Answer: 1375 m] *3. A fugitive tries to hop on a freight train traveling at a constant speed of 6.0 m/s. Just as an empty box car passes him, the fugitive starts from rest and accelerates at a = 4.0 m/s2 to his maximum speed of 8.0 m/s. (a) How long does it take for him to catch up to the empty box car? (b) What is the distance traveled to reach the box car? Solution (a)...

This ranges from electronic products to computer software and even liquid chemicals. Companies need to ensure their products reach their customers in the right quantity, at the right time and the lowest cost to maximize their profits. Logistics component of a company’s operation can be kept in house, if it is considered a key function; otherwise can be out sourced to an established logistics company, such as Federal Express (FedEx). Goods can be delivered via air, sea or land freight. Long distance deliveries use mainly air or sea fright, with land fright deployed when distance is relatively short or as a transfer of cargoes to and from sea ports or airports to the pick-up points or delivery points. Sea freight is the most common mode for transportation for long distance as compared to air freight, mainly due to cost. However, in the case of transporting of liquids, sea freight is perhaps the only mode for long distance. Tanker is the...

...beam, which traveled through air to the receiver. The flexible reflecting diaphragm (which could be activated by sound) was illuminated by sunlight. The reflected light was received by a parabolic reflector placed at a distance of about 200 m. The parabolic reflector concentrated the light on a photo-conducting selenium cell, which formed a part of a circuit with a battery and a receiving earphone. Sound waves present in the vicinity of the diaphragm vibrated the diaphragm, which led to a consequent variation of the light reflected by the diaphragm. The variation of the light falling on the selenium cell changed the electrical conductivity of the cell, which in turn changed the current in the electrical circuit. This changing current reproduced the sound on the earphone. Fiber Optic Technology Fiber Optic is a technology that uses glass as thin as a human hair to transmit data from one place to another by sending pulses of light through an optical fiber. The light forms an electromagnetic carrier wave that is modulated to carry information. A fiber optic cable consists of a bundle of glass threads, each of which is capable of transmitting messages modulated onto light waves. It is widely used for communications, which permit transmits data over longer distances and at higher bandwidths than other forms of communications. Fibers are used instead of metal wires because signals travel along them with less loss, and they are also immune to electromagnetic interference. Fibers...

...Transport Means & Modes 1- Transport Means : These means of transport are : Cars (trucks) , Ships, Trains, Planes and Pipes. These are the means which are used either for carrying people or carrying the goods from one place to another. 2- Transport Mode : Is the mode or the environment in which the mean is running or moving. Thus, we could say that the land roads are the mode for cars, buses and trucks. Sea is the mode for ships and marine crafts. Railway is the mode for trains. Air is the mode for the planes. And finally the pipeline is mode for pipe transportation. First : The Land Roads When building the roads there are certain requirements which should be considered and require special engineers who are specialized in this aspect in order to meet the local and the international requirements and standards which include the speed limits for cars and trucks, number of lanes, width of each lane, the degree of the steeps and the radius of the curves and many other things. Factors to be considered when planning for building a road : The highway roads and those which are designed for heavy lift trucks should pass out towns and cities in order to minimize traffic, noise and pollution inside the towns. When planning for a road or roads network it should be done to be capable of serving the future traffic considering the possibilities of the increasing population, number of cars and trucks and the expected increment in moving goods. Roads should...

The companies’ shipments are transported to its foreign markets by container ships. In Europe, the company ships to Hamburg and Gdansk where independent distribution companies have contracts to deliver its products throughout Europe. Recently, AIAI has been displeased with late deliveries and rough handling of their products. To make matters worse in their European market, trade barriers have fallen in the past five years, and European markets have opened up, and as a result, European businesses have expanded, there is more competition, and their customers have become increasingly demanding and focused on quality. As a result of the expanding European market, AIAI needs to start the process of selecting a new site for its European warehouse/distribution center. The European headquarters for AIAI are located in Hamburg. The VP of Construction and Development in Dayton, Ohio asked the Hamburg office to do a preliminary site search based on five factors: location, geography, transportation, proximity to customers, and costs.

...attention of the Wedding Guest, he starts telling a story about a disastrous journey he took. The Wedding Guest really wants to go party, but he can't pry himself away from this grizzled old mariner. The Mariner begins his story. They left port, and the ship sailed down near Antarctica to get away from a bad storm, but then they get caught in a dangerous, foggy ice field. An albatross shows up to steer them through the fog and provide good winds, but then the Mariner decides to shoot it. Oops.Pretty soon the sailors lose their wind, and it gets really hot. They run out of water, and everyone blames the Mariner. The ship seems to be haunted by a bad spirit, and weird stuff starts appearing, like slimy creatures that walk on the ocean. The Mariner's crewmates decide to hang the dead albatross around his neck to remind him of his error.Everyone is literally dying of thirst. The Mariner sees another ship's sail at a distance. He wants to yell out, but his mouth is too dry, so he sucks some of his own blood to moisten his lips. He's like, "A ship! We're saved." Sadly, the ship is a ghost ship piloted by two spirits, Death and Life-in-Death, who have to be the last people you'd want to meet on a journey. Everyone on the Mariner's ship dies.The wedding guest realizes, "Ah! You're a ghost!" But the Mariner says, "Well, actually, I was the only one who didn't die." He continues his story: he's on a boat with a lot of dead bodies, surrounded by an ocean full of slimy things. Worse, these...

...comparison with space travel to other bodies in the same star system. It is invariably more difficult, as the time and distance scale for such an endeavour is almost unimaginable Why we want to visit other stars? The group identified five key factors as high-level motivations for the exploration of distant space: • Human survival: ideas related to creating a legacy for the human species, backing up the Earth’s biosphere, and enabling long-term survival in the face of catastrophic disasters on Earth. • Contact with other life: finding answers to whether there is other life in the universe, whether “intelligent” life exists elsewhere in the galaxy, and at a basic level, whether we are alone in the universe. • Evolution of the human species: exploration as a human imperative, expansion of human understanding and consciousness through space exploration. • Scientific discovery: breakthroughs in scientific understanding of the natural universe, a pursuit for knowledge. • Belief and faith: a search for God or the Divine, a need to explore beyond Earth’s atmosphere as a part of natural theology or as found through religious revelation. These drivers for exploration were identified through group discussion as the most significant, high-level reasons why human societies and individuals would undertake the exploration of space over long timescales and distances. Survival was identified as a driver for space exploration through the potential to ensure human survival in the face...

...College of Distance Education NAVAL WAR COLLEGE Newport, R.I. An Analysis of the Argentine Center of Gravity in the Falkland/Malvinas Conflict By R. Walker A paper submitted to the faculty of the Naval War College in partial satisfaction of the requirements of the Department of Joint Military Operations The contents of this paper reflect my own personal views and are not necessarily endorsed by the Navy War College or the Department of the Navy 05 Aug 2007 On 2 April, 1982 Argentine forces invaded and captured the Falkland Islands. On 5 April, British Task Force 317 sailed from Portsmouth, England towards the South Atlantic. From 21 April, Argentine and British forces fought air, land and sea engagements on and around the Falklands, resulting in an Argentine surrender on 14 June. The Argentine military was hampered by many self-inflicted obstacles and did not achieve much operational success. The one area in which the Argentines did well was in their application of air power. In this air power we find the Argentine Center of Gravity; the Super Entendard aircraft armed with the AM.39 Air to Surface Exocet missile. This system alone had the ability and the opportunity to change the outcome of the conflict. The land and sea elements of the Argentine forces could not be considered as a Center of Gravity for many reasons. While the Argentines had a fairly capable navy, Admiral Woodward, the...

...way to the Revolutionary war where submarines were used to plant explosives on British ships. Then During the Civil War Submarines were very dangerous but used to liberate southern ports. Fast forward to the Great Wars Submarines revealed their true power in attacking surface ships. Today Submarines can strike land, air, surface ships, and other deep diving submarines making them the most versatile vessel in the United States Navy. They now also have the capabilities to gather intel from safe distances in the middle of the ocean. The Seawolf Class is arguably the most valuable and multipurpose Class of submarines ever created. It was original intent was to combat the cat and mouse submarine chase that was taking place with the Soviet Union during the Cold War. Unfortunately, when the first was commissioned in 1997 the Cold War was long over. These multibillion dollar submarines are no longer being made due to the hefty manufacturing price. However, there are still three Seawolf submarines that are commissioned in the fleet. One of them being the Jimmy Carter which is known to be the predecessor to the Seawolf Submarine Class in the Los Angeles Class. According to military.com the...

...Military Technology Technology in the military has greatly increased strength and eased the ranking among world powers and effected the development of new military weapons. The term "Survival of the fittest" means that the strong will succeed but the meek will not, this is the case with military technology. The U.S. has the best technology in the world, therefore we are the highest military power. Technology is a very important part of warfare. Technology is driven by the military. The army's race during the cold war, spawned some of the greatest technical achievements in human history. Space travel for example is a result of the X-plane project. The Internet was produced by the military as well. If we stop investing in military technology, we risk our safety. If other nations had more advance technology than we do, they would have more power than we do. If that was to happen, we face the threat of that nation taking over us. Military technology may be divided into five categories. Offensive arms harm the enemy, while defensive weapons ward off offensive attacks. Transportation technology moves soldiers and weaponry; communications coordinate the movements of armed forces; and sensors detect forces and guide weaponry. There are many types of technological developments in the military happening at all times. They range from new aircraft to sophisticated guidance systems. Teams of specialists work for years to develop some of our simplest equipment. These people's...
