Answers: 1.Define what a philosophy is and the job it serves in venture the executives. Venture Methodology This is identified with the arrangement of practices, methods and the strategies that contain all the directing procedures for the individuals who are dealing with the undertaking the executives. They are not apparatus explicit rather they are the product dependent world with the strategy of the association undertaking and the board programming device that are interwoven. With the adjustment in the building and the development, there are diverse administration forms where the framework can work with better administration. (Cooper, 2016). For this, there is a need to concentrate on the product advancement and IT activities with the goal that it is anything but difficult to think about in the middle of the techniques for dexterous, cascade and so forth. Job in Project Management With the changed philosophies, there are steps which incorporates the commencement, arranging, executing, controlling and afterward shutting the work.

The business chips away at the monotonous and the other utilitarian exercises to deliver the items with simple way to deal with the specialized and task the executives techniques. The essential limitation for this is the degree, time, quality and spending that should be set with the streamlining of distribution for all the vital sources of info and afterward applying them to address the issues and the targets.

The boundaries are set apart with the capacity identified with the individuals, innovation, correspondence and the assets that would prompt keep up the undertaking the board practice with the ability to stamp the solid and the unbending philosophy. 2.Choose two techniques from this rundown to look into The dexterous strategy is the best which chips away at giving the quick and the ceaseless conveyance of the item for the client. It deals with the customary strategy like the cascade and the other straight procedures which are significant for characterizing the necessities dependent on the start and the finished result arrangement. The Agile is characterized through the finished result and afterward beginning where there is an appropriate portrayal of the prioritization procedure. There are non-static prerequisites, adaptability, steady change to deal with the correspondence approach with the improved culture and procedures. (Gregory et al., 2016). The product improvement works with the methodology that holds the various sorts of the ventures, where the clients can deal with the lightweight undertaking the board so they can convey the work in the short time span than the interest of Agile. The Agile chips away at the people and the connections over the procedures and the apparatuses, where the working programming is set with far reaching documentation. The joint effort with the client and afterward reacting to the adjustment in the plans is significant. There are requirements for estimating the extraordinary deftness in the necessities and afterward setting the short-named conveyance cycles and the dynamic group culture which is prohibitive for the on-time genuine correspondence. The cascade model is the one which is for the enterprises and to chip away at the product improvement with development. It moves in the direction of the turn of events and how they can deal with the elevated level stages where: The prerequisites particulars are required. Structuring Development Reconciliation Testing and investigate Establishment and support. The cascade model incorporates the venture the executives strategies where each progression is pre-arranged and laid in the correct way. (Ahimbisibwe et al., 2017) Through this, there are potential outcomes to roll out any improvements in the clients needs and work on the groupings of the undertakings which are hard to oversee, something else. This needs to deal with the product advancement ventures with the improvement through the fixed stages and the straight courses of events. Here, the emphasis is likewise on holding fast to the necessities and conveying the venture in single with the long cycle. The necessities are set to characterize the highest point of the cascade where each stage should be finished before the following stage can start. The cascade approach is where the result on the one stage goes about as the contribution for the following stage in consecutive way. After the arrangement is seen as affirmed, at that point there is an almost no degree to adjust to the plans t ill there are changes dependent on the solicitations change. the venture works through the stream from the prerequisites, with structuring usage and testing. The single cycle approach in the cascade is to keep up and ponder the degree to adjust to the various changes with the scorn in the offices which are wasteful. The Waterfall techniques can be effectively working and anticipating when the necessities are fixed with the well-documentation and clear system arrangement. For this, the cascade additionally need to furnish with the final products for the financial plan and the course of events with specific degree limits. Likenesses and contrasts between them both. Advantages over cascade model and nimble model 3.Finally, recognize how your picked philosophies and procedures identify with the task life cycle (PLC): The light-footed programming improvement deals with the various arrangements of qualities and standards which is for the product advancement till there are necessities to deal with the arrangements. It accompanies the synergistic exertion for self-association of the cross-useful groups, where there are support arranging, transformative turn of events and simple conveyance with progress. The structure is characterized dependent on the product improvement and afterward dealing with the collective impact that would advocate the arranging, adaption and afterward setting the reaction to change. The strategies are portrayed through the rising fast application improvement and iterative methodology. The undertakings are conveyed for the particular highlights where the people and the associations resemble the co-area and the pair programming. (Mitsuyuki et al., 2017). The client coordinated effort is likewise for the prerequisites that can't be simple assembled in the first place however they are because of the different components like the client communication and reaction to the change. Here, the prescient arranging is for the versatile programming improvement measurements where the customary cascade model backings the prescient methodology. Here, the prescient models and the anticipating depends on the prerequisite examination and the arranging. This aides in dealing with the progressions according to the component necessities. The client cooperation is significant in the spry approach for the open correspondence with limited documentation highlights for the joint effort. There are approaches for the product advancement to advance the collaboration and broadly educating, where the usefulness depends on the turn of events and exhibit of the procedures. (Merhout et al., 2017). The asset necessities are required which are least and appropriate for the fixed or the evolving prerequisites. The light-footed model likewise chips away at the exacting conveyance the board pro cedure where the usefulness is mapped to convey and deal with the changes in accordance with comply with all the necessary time constraint. This relies upon the client collaboration with the more elevated level of the individual reliance where there is a chance of least documentation created. The cascade model chips away at the venture lifecycle where the structuring approach is set to deal with the various procedures with simple portrayal of the necessity examination, framework planning, execution and the testing. The prerequisite social affair and the investigations is for the arrangement that should be assessed dependent on the contributions from the framework plan and setting the little projects which are called units. The following stage joining forms are through the coordination and testing that would be significant for the utilitarian and the non-practical prerequisites. The item sending is done through the client condition where the upkeep comes up when the customer condition is set to fix the issues and the patches are discharged, from that point. The product of the cascade model chips away at the prerequisites which are plainly reported, clear and fixed, with the items steady and justifiable innovation. (Poston et al, 2016). This would permit the departmentalisa tion and controlling the calendar with legitimate cutoff times for each phase of advancement so the item can without much of a stretch be set through the improvement procedure. This moves from the idea, structuring and the usage, testing and establishment that would wind up at the activity and ready to keep up with the unmistakably characterized stages. (Vijayasarathy et al., 2016). Through this, there is a chance of the advancement where the application is set in the testing stage which isn't reported in an appropriate way, and sums to the high dangers References Ahimbisibwe, An., Ahimbisibwe, A., Daellenbach, U., Daellenbach, U., Cavana, R. Y., Cavana, R. Y. (2017).

Atom Model Theory - Free Essay Example

History of the model of the atom The atomic theory is developed since 2000 years ago the Greek philosopher Democritus proposed that there was a limit to how small one could be divide matter, this smallest matter indivisible particle was called atom. However this atomic theory of Democritus was criticized by Aristotle who proposed a model based on four basic elements of earth, air, fire and water. Aristotles view held for the next 2000 years as it better suited religious beliefs of the time. In 1801, an English teacher named John Dalton proposed his atomic theory which stated matter is composed of all small indivisible atoms, elements contain one type of atom; different elements contain different atoms, compounds contain more than one type of atom. In 1904, British physicist J.J Thomson and others demonstrated that cathode rays (electrons) were present in all matter. Thomson proposed that the atom was a sphere of positive charge in which embedded were rings of negative charges (electrons) , like plums in a pudding. Lather on, in 19 century, the discoveries of radiation leads to a new progress of Physics. We knew that certain elements emitting radiation, this suggested that atoms are no longer indivisible and not indestructible, as proposed in Daltons atomic model. Radiation provides an important tool for the study of matter. In 1911, Rutherford first suggested the use of alpha particles to probe the internal structure of the atom. Finally, the nucleus and its pr otons were discovered. Rutherfords scattering experiment Ernest Rutherford, directed an experiment to Hans Geiger and Ernest Marsden in 1909, in which the newly discovered alpha particles (Helium nuclei) were fired at a thin gold foil layer which only a few atom thick. At that time the atom was thought to be analogous plum pudding by Thomson with a negative charge (the plum) throughout the positive sphere (the pudding). Most of the alpha particle passed through with no or only very small deflections in a vacuum (see figure), as would been excepted on the Thomson model of the atom current at the time. About 1 in 8000 was deflected through angles greater than 90 degree. The result was so unexpected that Rutherford was very unexpected that Rutherford was promoted to writeà ¢Ã¢â€š ¬Ã‚ ¦.it was almost incredible as if you fired a 15 inch shell at a piece of tissue and it came back and hit you. Therefore Rutherford concluded that majority of the mass of the atom was concentrated in the nucleus. The small size of the nucleus explain ed the small number of the alpha particles that were repelled each other in this way. Rutherford showed that the size of the nucleus was less than about 10 -14m. Bohrs model, how it fit experimental observation Accelerated electrons emitted and lose energy which predicted by Predicted by Maxwell and confirmed by Hertz, however the electron doesnt spin into the nucleus because of energy losing. Later on, In 1903.H.G.J Morseley found simple, regular relationship between the frequencies of X-ray emission line, thus it provided an evidence to support Bohrs model. Scientist began to work on an alternating model to replace it. Bohrs postulates In 1913 the Danish physicist Niels Bohr (1885~1992), put forward some radical propositions to account for the discrepancies between Rutherfords model of the atom and the available experimental evidence. Bohrs postulates are 1. Electron can remove in certain allowed orbitsstationary states (energy) without radiating energy. 2.when an electron falls from a higher energy level to a lower energy level, it emits energy that is quantised by the plank relationship E2- E 1= hf. 3. Augular momentum (mvr) is quantised and can only take values of the nh / 2à Ã¢â€š ¬ when n is the principal quantum number. The first postulate account for the stability of the atom. However why the these stationary state excited was unknown. They exist was a fact. The second postulate explains the line emission spectra. Emission (or absorption) of Energy is discontinuous and corresponds to a transition between two stationary states. Since the energy can be quantized, the emission, the frequenc y of the emitted (or absorbed) radiation is predetermined. A transition between different states will lead to difference frequencies or colours. The third postulate effectively sets limits on the radius of the allowed orbits. Bohrs model Bohr realised that if his model was correct, each atom would have a spectral fingerprint to the differences between electron energy level in that atom. The Rydberg equation which also known as Balmer equation, has given him evidence for the quantised emission of the energy from hydrogen atom, leading him to going on to further his model and define his postulate. So the hydrogen spectrum was very significant to the development of Bohrs model of the atom, because without the understanding of it, Bohr may not continue his work of the model. Produced and observable when hydrogen gas was excited by the addition of energy. The equation in the original form was modified by Rhydberg until it worked and could be applied to explain the spectrum of hydrogen by using integer values of n, only as suggested by Bohr in his postulates. Quantum number and quantum changes Its possible to determine the energy of each orbit using Bohrs model and from this construct an energy level Figure for hydrogen. The figure below shows the energy these energy levels. Alternatively a transition between stationary states can be show in figure. B. The Balmer series of lines occurs when the electrons fall to the n=2 level from n=2 level n=3,4,5 and 6 levels. This is illustrated differently in figure. B. How Bohr describes the hydrogen spectra Bohrs model of the atom wad quite similar to that of Rutherfords with two important differences firstly, it assisted positions to the electrons, but secondly the electron energy level s were quantised. This was radically new, the idea that electrons had energy states and could absorb and emit energy to change states, and had no evidence. Bohr realised that if his model was correct, each atom would have a spectral fingerprint to the differences between electron energy level in that atom. The Rydberg equation provided him evidence for the quantised emission of the energy from hydrogen atom. It leads him to going on to further his model and defines his postulate. So the hydrogen spectrum was important to the development of Bohrs model of the atom. The energy levels describe by Bohr is clearly marked. According to Bohr, the Balmer series (shown on the bottom of the diagram as the hydrogen spectrum) was cause by changing energy levels, in the process releasing light. As sho wn, larger energy changes produce more energetic photons, as seen in Balmers series, as further, this diagram shows how the Balmer series is formed by successive electron transition to the 2ndshell (transition to other shell produce additional lines named after their discoveries.) This is a great achievement that the Bohr s model is able to provide a physical basis for the Balmer series formula. From his second postulate E f- Ei= hf. (i) states for initial energy level (f)states for final energy level Ei=1/ni2E1and Ef=1/nf2E1 hence: hf =1/ nf2E1-1/ ni2E1=(1/ nf2-1/ ni2) E1 And since c=fA=A=c/f the expression reduces to 1/A=E1/hcX(1/ nf2-1/ ni2) where R states for Rydbergs constant, RH(hydrogen)1.097X 107m-1. By using the mixture of classical physics and quantum physics, Bohr was able to define the equation for the spectral lines of hydrogen. He didnt know why the electrons obeyed his rules. These were purely empirical results. Problems with the model For all the success, the Bohr model of the atom had serious limitations: It and ad hoc mixture of classical and quantum physics; it allows some laws of the classical physics held and others did not. Hydrogen has only one electron, and Bohrs postulate are only able to explain it. It cant work fo r multi-electron atoms. It could not explain the relative intensities of the spectral line; some lines were more intense to the others and it was not known why this should occur. Certain spectral line were foun of a number of very fine and close lines and the cause of these hyperfine spectral lines could not be explained. The splitting of spectral lines when the sample was placed in a magnetic field (called the Zeeman effect, and discussed below) could also not be explained. The postulates faced a problem that it is suited for larger atom. Hydrogen is the simplest atom containing only one electron. Similarity He+and Li+have one electron. Bohrs model works with theses atom and ions . In all the other atoms however the electron interact with each other. In a larger atoms the outer electrons are shielded from the nucleus by the inner electrons. Interaction between electrons also result in different energy levels. The affect Bohrs model to the extent that the spectra of multiple electrons could not be explain. When the spectrum of the hydrogen was examined it was noted that the emission line varied in intensity. Some were quite intense and others were less intense; some were sharp and some were boarder. The following figure. illustrate these differences. Bohrs model could not explain these features but later it was explained that electron orbited in a ellipse and not in a circles. As the developing of the light spectroscopes improved it was found that some of the spectral lines were made up with hyperfine lines. This suggestion spitted Bohrs energy level theory; however there was no explanation for this. The Zeeman Effect Zeeman Effect occurred when a magnetic field us pass through a discharge tube. The magnetic field increased the hyperfine splitting of spectral lines, further breaking them up. As the limitation, Bohrs model was unable to explain the experimental evidence. In 1896 a Dutch physics Pieter Zeeman (1865-1943) found that when he placed a source of sodium light between the poles of a strong magnet the lines split into three or more. This could not explain by Bohrs model, The spectral line of some elements can even split to 15 lines. This is called the anomalous Zeeman effect. It cant be explain by that time, and it leads to the new developing of the model to explain it. This begin with the work of de Broglie. The following is the formal definition of Zeeman Effect: The splitting of single spectral lines of an emission or absorption spectrum of a substance into three or more components when the substance is placed in a magnetic field. The effect occurs when several electron orbi ts in the same shell, which normally have the same energy level, have different energies due to their different orientations in the magnetic field. A normal Zeeman Effectis observed when a spectral line of an atom splits into three lines under a magnetic field. Astronomers can use the Zeeman Effect to measure magnetic fields of stars. The following diagrams shows the normal spectral line and the Zeeman effect. References Textbooks 1. Excell HSC physics by Neville Warren published in 2007 2.
