rpdf 214 Explain the relative boiling point values for the following compounds. The boiling point of H2S is-60Â°C, whereas that of water is 100Â°C. The boiling point of HF is 19.5Â°C, whereas that of water is 100Â°C. C. (G) (ii) d. (i) (ii) (ii) State whether you would expect borazine to be more or less reactive than Draw out the structure of borazine Give a brief description of the bonding in borazine. benzene. Explain your answer. Using structural diagrams, briefly explain the difference between a silicate and a silicone. Solution 1C) H2S has low boiling point and exist in gas form where as H2O has higher boiling point and it is in liquid state.This is due to the presence of strong intermolecular hydrogen bonding in water. H2S is not having intermolecular hydrogen bonding. HF also having intermolecular hydrogen bonding but having less boiling point thah that of water. HF combines with another one more molecule of HF, where as H2O has extensive hydrogen bonding.Due to this H2O has higher boiling point. .

Virtual Computing Questions.. Answer both questions in 500-600 words What is Xen? Are there other virtualization technologies that are gaining ground? (Perhaps internationally) Solution 1 ) Xen : Xen is an open source virtual machine monitor(VMM) for X86 compatible computers.Xen facilitates to run multiple operating sytem on a single computer with the help of a software layer called hypervisor .Hypervisor act as a traffic cop,directing hardware access and coordinating request from guest operating systems.it can securely execute multiple virtual machines,each runs own its own OS. Xen can run Linux, Solaris,Windows and some of the BSDs as guest on their supported CPU architectures. Xen was first released in 2002. \'Xen source.inc\' and \'Virtual iron software inc\' promoted Xen as a primary open source competitor to commercial virtualization products such as VMWare. Xen released under the terms of GNU General Public Licence, was originally a project at the University of Cambridge. 2 ) Apart from Xen a new virtual machine called KVM ( Kernal-based virtual machine ) gaining more popularity.KVM is a light weight hypervisor for linux. KVM is relatively new comer but its simplicity of implementation and strength and continued support of Linux heavyweights make it worthy for serious consideration. some of other popular virtualization technologies are, oVirt Ganeti Packer Vagrant VirtualBox Xen is a Virtual machine which can run multiple Operating system. this is done with the help of \"hypervisor\". hypervisor act as an intermediatory. It takes request from user and giving access to operating system. Xen can run Linux, Windows, Solaris etc. .

Virtual Computing Question.. Answer the following question that listed below.. also provide one Reference This scenario involves the integrity portion of the CIA Triad. The integrity portion of the triad deals with maintaining the accuracy and trustworthiness of data over its life cycle. Jim, the virtual server manager, wants to send three separate documents to users on his virtual server; one document for each person. Therefore, each document has to travel from the server to a client machine on the network. The virtual machine manager is Oracle VirtualBox and each client has a different operating system on their system: one has Fedora Linux, one has Microsoft XP, and one is running Mac OS X. What will ensure these documents travel to their recipients without being changed en route? What precautions should Jim take before sending them? Also, will one client operating system be more at risk of their packet being sniffed or changed? Solution The docs will be reached on client site without being changed which is ensured by Data Encapsulation provided by TCP/IP Protocol and by resilient and scalable networks, Encryption also plays an important role in this Jim has to take the following steps First use the VPN Second use security concerns like Encryption, password protection It depends upon the schema which a OS applies for data decryption because the data transmission doesnt care about the OS of the Recipient, so the risk always lies on the client side not on the medium .

Ventura Capital is a financier who specializes in capitalizing start-up companies. Andy Preneur is a would-be entrepreneur. He needs capital to start his new business. Andy and Ventura have been negotiating a potential agreement over the last few months. It seems there is only one item unresolved. Ventura wants her investment to remain in the company and earn a preferred dividend of 5 percent, even if Andy no longer needs the money. Andy wants the right to buy out Ventura\'s interest any time as long as the 5 percent return is paid. Role-play this case with another person (does not have to be a classmate, just someone, such as a friend or family member, that can take the opposite position and assist you). When you finish, address the following questions. 1. Which of the four key temperments was most clearly displayed by the other person? Identify specific comments and behaviors to support your assessment. 2. Which of the four key temperments do you think your comments and behaviors most clearly displayed? 3. Do you agree with each other\'s self and other assessments? If not, why do you think you see the behaviors differently? Solution Venture Capitalist is a person who invests money in new ventures where traditional banks and financial institutions donot want to put money. In such a scenerio the entrepreneur who is seeking venture fund is at a receiving end and hence has poor bargaining power. On the otherhand the venture capitalist has higher bargaining power as he is taking risk in putting money in a new untested project. Therefore , if the venture capitalist wants 5% preferred share to continue , perhaps the entrepreneur should agree to it. In the long run if the venture capitalist gets a better opportunity , he will definitely close the preferred stake in the current venture and invest in the new venture. .

VB -What is the primary advantage to defining an interface type in an application? Solution using interface make it possible to treat different type of object the same way. you could define an Interface IDrivable could define method such as StartEngine, MoveFoward, MoveBackward, TurnLeft and TurnRight. you could then have a Car class which implement the IDrivable interface as well as Bike Class. and in your code, you could have a loop to mixed array of Car/Bike and obj[0] = new Car(); obj[1] = new Car(); obj[2] = new Bike(); and have a for (int i = 0; i < obj.Count; i++) { ((IDrivable)obj[i]).Start(); ((IDrivable)obj[i]).MoveBackward(); } This is only a simple application of what an Interface can do ! Upon that few more advantages are:- -Knowing for certain that specific methods and/or properties are available -Ablility to call those methods/properties without knowing anything about the derived class Hope this help! .

Valence electrons are not responsible for A. B. O D. The chemical reactivity of an atom The bo atom The characteristics of an anion or cation The electron affinity of an atom nding characteristics of an E. Why atoms are in the same group on the periodic table Solution Answer is :- C. The characteristics of an anion or cation. The valence electron is mainly responsibe for chemical reaction they involved in the electron transfer and electron acceptor to produce the new molecule. Then the bonding nature of the atom mainly depends on the number of valence electron if it has three elctron then atom having the abilitity to form triple bond. The valence electrons does not provide any idealogy of the charecteristics of the cation and an ion like when it react and or not. Then valence elctron is responsible of the electron affinity and group to place element. same numer of valence electronic atoms are placed in the same group. .

Week 2 Discussion: I need help understanding the following question: Consider the place where you live (city, town, county, state etc.) and think about local housing market, what can we say about Demand and Supply for housing as related to a geographic area? How would we tie this into current economic conditions? Hint: Consider factors (e.g more green jobs, tourism, etc) that contribute to stable/rising housing market and factors (e.g. disaster prone areas, pollution, etc.) that lead to the opposite. You can all use T-I-P-E-N and P-R-E-S-T to explain why housing prices vary from one city to another. Solution One could drive until the household qualifies for a mortgage. The willingness to migrate for affordable housing considerably expands the geography of supply. The result is sprawl. Sprawl bad. The push for greater density is normative, a geographic fetish. Expanding the geography of supply is not OK. Suddenly, the real estate market doesn\'t look so agnostic. Regardless, sprawl is one way a region can deal with a problem of housing affordability. Migration is a lot nimbler than changes to zoning and casting bedroom eyes at real estate developers. I would hope that all readers appreciate that geographic scale impacts the supply of housing. The point of greater density is to make a hot residential neighborhood affordable, not an entire metro area. Proponents of greater density promote the geographic distortion of housing supply, not a less regulated real estate market. The dense mixed-use urban utopia of walkability is this generation\'s suburban idyll. .

We will assume the universe is expanding at a constant rate. At t = t0Â another galaxy is a distance D0Â away from us as shown in the diagram. For the purposes of this exorcise it will be easier to think of the other galaxy being at 0 and we are moving away from it, with us being at location D0Â at t0. 1. If we assume the two galaxies were at the same location a t = 0, find an equation for the distance between the galaxy as a function of time, D(t). 2. Find the speed at which the galaxy are moving apart. 3. At t0Â light leaves the galaxy at 0 headed for us at a speed c. How long does it take the light to reach us? Do not forget to include the fact that we are moving away from the other galaxy, which means the light will have to travel farther than D0Â to reach us. Solution if we assume constant rate of expansion of the universe then for a distance s between two galaxies their rate of seperation is ds/dt = k ( where k is a constant) given distance at t = to is s = Do distance at t = 0 is s = 0 distance at t = t is s = D(t) hence ds/dt = k s = kt + c ( where c is another constant) hence Do = k*to + c 0 = c hence k = Do/to hence s = Do*t/to 1. D(t) = Do*t/to 2. speed at which they are moving apart = v v = ds/dt v = d(D(t))/dt = Do/to 3. at to, light leaves galaxy at x = 0 it reaches us at time t = to + t then time taken for it to travel distace = t distance = Do + v*t hence Do + v*t = c*t hence t = Do/(c - v) = Do/(c - Do/to) .

We normally think of the arts as very different from technologies in spite of the fact that art (with perhaps a few exceptions) is practiced with the help of technology. This practice creates interdependence between technology and art. To what extent does art respond to, or is shaped by, the technology that enables it? To what extent have advanced and accessible digital technologies, such as websites, digital photography, and YouTube, changed the relationship between art and technology? Are these technologies reshaping our attitudes toward artists? Solution Ans; Art, to a very large extent, is shaped by the technology that enables it. In fact it is technology that led to invention of portable paint tubes, a pre-requisite for most art forms. Technology provides a medium, a way to the artists to express themselves. For example silkscreen painting as an art form is a technological find. The digital revolution which is taking place, thanks to the new and emerging digital technologies is strengthening the bond between art and technology. Digital technologies helps artist innovate and apply new methods to present their art. For example \"the petting zoo by mimimaforms\" uses technology to showcase their art work. (this can be viewed on youtube). Yes, these technologies are re-shaping our attitudes toward artists. Earlier artists and their art works were considered exclusive, meant for the rich people. With technologies like websites, youtube etc. even common people belonging to the middle class can have access to the artworks and this has changed attitude as artists and their art works are now considered more inclusive. .

To what extent have advanced and accessible digital technologies, such as websites, digital photography, and YouTube, changed the relationship between art and technology? Are these technologies reshaping our attitudes toward artists? Solution Interest in new technologies on the part of artists has always been an important element of the development of art, but it was only in the 1960s that the creative practices known today as the main reference point for technological art were established. Such new initiatives appeared in the Poland of the 60s, during the Thaw period, when the attitudes towards activities at the interface of art, design, and technological development were much more accepting. This includes, among others, works created at the Polish Radio Experimental Studio, as well as the artistic practices stemming from Mieczysaw Porbski\'s seminars, devoted to the relationship between art, science, and technology (participants included Ryszard Winiarski, Feliks Falk, and Grzegorz Kowalski). 1 Other artistic phenomena involving art and technology include some works created at the Workshop of the Film Form, and the later solo works by such Polish artists as Krzysztof Wodiczko orZbigniew Rybczyski. .

We have two oscillators, used to measure time. One is a vertical mass-and-spring system. The other is a simple pendulum. On earth the two systems have the same period. How do their periods compare on the moon? A. Both periods become longer. B. only the pendulum\'s period becomes longer C. Only the mass-and-spring\'s period becomes longer D. Neither period changes at all. E. none of the above If a mass hangs from a vertical spring and is moving up and down, you take one video of the motion on earth and then take another video of its motion on the moon, can you tell the difference between the two motions? Solution time period of simple pendulam= 2*pi sqrt(l/g) so time period inversly propotional to gravitaion constant. time period of verticle ossilator= 2*pi sqrt(k/m) so time period does not depend on g. we knows g of moon < g of earth. so on moon g is less then that of earth. so g decreases, so time period of pendulam increase as time period of pendulan is inverse of sqrt g. and time period of oscillator remains the same. so option B. only pendulam\'s timeperiod becomes longer. .

S8-6 (Learning Objective 4: Explain goodwill and minority interest) Two accounts that arise from consolidation accounting are goodwill and noncontrolling interest. 1. What is goodwill, and how does it arise? Which company reports goodwill, the parent or the subsidiary? Where is goodwill reported? 2. What is noncontrolling interest, and which company reports it, the parent or the subsidiary? Where is noncontrolling interest reported? Solution a. The Goodwill refers to the Intangible asset, this basically arises when one Company acquires the another Company on premium, the goodwill value arises out of the firm client base, employee relation and Company\'s brand name. The Goodwill is reported in the Balance sheet at the asset side side and is reported by the holding Company, since they consolidate the accounts of all the subsidiary Companies, hence they consolidate the assets size of all the subsidiary Companies. b. The Non controlling interest refers to the minority interest, wherein parent Company holds few of the shares but the impact of that ownership is not very much significant to have a impact over the decisions of the Company. The Non Controlling interest is reported by the parent Company at the Assets side as it is a investment by the parent Company, while preparing consolidated statements. .

rtrs Solution The Round Table on Responsible Soy was founded in 2005 by the World Wildlife Fund and the Swiss supermarket COOP. The aim was to make mainstream soy more responsible. The organisation has since been taken over by the industry and consists mainly of producers, banks, traders and industry. Members are for example Cargill, Monsanto and Syngenta. Shell and BP have also joined, because of the use of soy as a biofuel. Very few organisations from civil society take part. No organisation of small farmers or indigenous people is involved. The only organisations that try to give an independent status to the RTRS are the WWF and the dutch NGO Solidaridad. The latter is at the moment president of the RTRS and is heavily sponsored by the Dutch government for this job. From the start the RTRS has been heavily critisized by a large number of organisations from all countries, including the countries that suffer from soy production. The main critisism is that the soy monocultures can never be responsible and the RTRS is only greenwashing the massive destruction from the production of soy. Even worse, it is paving the way for GM crops. WWF and Solidaridad should seriously reconsider their position and the effect of their actions. .

Why most of alpha particles passed through the foil? Why Some of the alpha particles bounced back from the foil? Q2. Sketch an electromagnetic wave and label the wavelength and an amplitude and which part of the electromagnetic wave provides information about the number of photons? INSRT STD Solution Rutherford experiment overall shows that atom has its most of space empty. And only central part of atom has mass confined of atom in form of nucleus. A. Electrons revolve around nucleus in an atom. The space between the orbitals is empty and that\'s why most of alpha particles passed through the coli. Because they passed through the empty space within the orbitals. B. Some alpha particles were bounced back because they collide with the nucleus which is present in the middle of atom. The mass of atom is in the nucleus so the alpha particles collided and were bounced back. .
