Now that you are familiar with vector spaces, try determining if other sets of objects meet the requirements (or not). For example, the set of integers, the set of rationals, the set of positive continuous functions on a closed interval. Do these meet the definition of a vector space? If not, why? Can you think of other examples from your past? Thank you. Solution set of integers are not vectors space .......becaue . take any integer say ; 6. now take any real number say; 3/5 but; 3/5*6 = 18/5 .......but this is not an integer .so ; it is not closed under scalar multiplication . so; set of integers are not a vector space set of ; rational are also not vector space . because; take any a rational ......2 now you take a real number (scalar)Â Â Â Â Â Â squreroot(2) . now; swqurt(2) *2 = an irrational number . so; rational are not alosed under scalar multiplication. positive continuos functions are not vector space under addition because ......in this case there will no inverse of any given function.also; positive conctinuos functions are not vector space under multiplication:) because if .......Â Â f and a is any negative real number then a*f = is a negative continuos function :) again it is not alosed under scalar field. now you can construct a vector space . it is ........ set of all 3 cross 3 matries which are invertioble .......under matrix multiplication . good luck!!!!!!!!!!!!! .

Nuclear disarmament should result in the retrieval of large amounts of plutonium from nuclear weapons that are being destroyed. Suggest one method for disposing of this plutonium and one method for repurposing this material. Some people have suggested that radioactive waste should be shot to the sun or outer space. List two reasons that this is not an attractive disposal method. Solution There are several methods to dispose of nuclear waste. However all methods have certain advantages and disadvantages. We cannot use storage containers to dispose plutonium because of its great half life of around 24000 years. We can bury it deep down but it has been proved dangerous . Plutonium can be used to power the reactors but it is a lot more expensive then we think. It is better to dispose off plutonium in water ponds and make use as needed. Why disposing nuclear waste in space is not a good option ????? It would be too costly, but there is a bigger reason not to launch nuclear waste into space: safety. The failure rate may be good enough when the only lives at stake are those who willingly went aboard, but when there is a chance that an explosion in the atmosphere will disperse nuclear waste over a wide area, the failure rate must be much, much lower. It would be a very, very, very bad idea to leave nuclear waste in LEO, so you would actually need to blast it off to deep space. This is exponentially more expensive. Further, if we balst it into space, the material may make an orbit around earth which will affect the incomping sunlight and may enter earth\'s atmosphere because of high half life .

NO2 is a yellow gas responsible for the brownish haze that builds up periodically over large cities like Los Angeles. NO2 readily decomposes to NO + O in sunlight (a reaction called photodissociation ). NO2 + hv -> NO2* -> NO + O ground state excited state You can assume the relevant part of the molecular orbital diagram for NO2 (HOMO and LUMO) closely resembles the diagram for O3, shown above (although the number of valence electrons is not the same). b. Which electronic transition (movement of electron from one orbital to another) accounts for the yellow color? c. Explain why the excited state molecule is more likely to undergo photodissociation than the ground state. Solution Nitrogen dioxide has one unpaired electron which makes very reactive.nitrogen dioxide gas is also very toxic. When heated to higher temperatures its color becomes dark and eventually brown gas. When it is cooled down, the color becomes yellow then more paler and subsequently colorless. The color of nitrogen dioxide gas is consequence of absorption of light in 400- 500 nm region. The brown color is complimentary color of green - blue color which is absorbed at 400- 500nm. The transition is likely to be n??* . .

No need for any sort of explanation. Please only a straightforward answer with no additional explanation. As few steps as possible. Kindly type clear. Solution (a) Hume-Rothery rules named after William Hume Rothery are the set of rules which states the conditions in which an element can dissolve in a metal resulting in the formation of a solid solution. There are two set of rules: 1. Substitutional Solid Solutions 2. Interstitial Solid Solutions There are different rules for both types of solid solutions. (b) Frenkel defect is a defect which occurs in crystalline solids when an atom or ion(normally cation) leaves its own lattice site and occupy an interstitial site thus resulting in the vacant site. This defect occurs in lattice structures which are relatively open and possess low coordination number. (c) A Schottky defect is a vacancy defect in ionic solids. It occurs when an equal number of anions and cations are missing from the lattice. It occurs in ionic compounds of high coordination number in which anions and cations are of the same size. (d) Domain boundaries can carry information and act as memory devices. Domains are bulky objects in which large response to changing external fields is due to change in volume which results in the movement of domain boundaries. .

olecular Forces liquid and sold states, molecules are held together by attractions called intermolecular forces. There are several types of intermolecular forces London dispersion forces, found in all substances, resuit fom the motion of electrons. These work to atract both polar and nonpolar molecules to one another via instantaneous dipole moments Dipole-dipole forces arise from molecular dipole moments lon-dipole forces result from the interaction of an ion and a molecular dipole attraction of a hydrogen atom bonded to a small highly electronegative atom (N, O, and F) and the unshared electron pairs of another electronegative atom cal propertles such as beiling point, melting point, vapor pressure, viscosity, and surface tension are all affected by the strength of the intermolecular forces within a subatance Part A Mhat happens to these physical propetios as the shengh of intermnoleoula forces increases?

Often in science it is helpful to talk about a representative example of the objects or phenomena being studied. However, you must always keep in mind that the average case is not always representative. For example, our Sun is often described as an \"average\" star in the Milky Way. In what sense is this statement true? In what sense is this statement seriously misleading? Do you think it is useful to characterize the stars in the Milky Way by simply citing our \"average\" Sun? Solution Our galaxy is comprised of millions of stars spread over tens of thousands of light years and each of these has planets of their own. Stars are divided into classes and ours is a G class in the middle of its lifespan, there are tons of different types of stars from blue giants, red giants, hypergiants, neutron stars, white dwarfs, red dwarfs, brown dwarfs and a thousand others. However the Sun is a very average star indeed there is nothing special about it other than having a planet orbiting it with life on it. It was born out of the ashes of other stars before it and will die like its predecessors to become part of other star billions of years from now. The Sun is not anything special at all it is a main sequence star but if it makes you feel better the majority of the stars are dwarfs in our galaxy however in relative terms the Sun is still very average. I don\'t know what makes you think this is misleading because that idea that we are special or our sun is died out a long time ago with the rest of the religious bigots and narrow minded individuals of past centuries. .

Obstacles in EHRs Implementation Discuss the major local, national, and international obstacles to implementing standardized terminologies within EHRs. Solution there are many obstacles in implementing the EHR in a real world. they are it is very costly process so many are not willing to change in their working environment technicakl skills are recquired softwares related to the EHR should be developed technical barriers organizational limitations and their attitude and behaviour of that people there is no sharing and accessing of data in state wide national wideor international wide to help the patients when necessary every people health data must be stored in the digital form so that it will be helpful for the doctors to know the report of the patient but maintaining every people record from the starting of their life is very difficult because the volume ofthe data is very huge and the velocity of the data is also becomes huge. so there are technical limitations and we have to over come the problems by using big data,map reduce,haoop programs. .

o be (11) Explain why an object (like a pencil) that is partially submerged in water appears to be bent. Solution The reason behind this phenomena is refraction of light in two medium.. The light as we know needs a medium for its propagation. Every medium has its own refractive index which is usually taken with respect to air. For sake of simplicity the refractive index of air is taken as unity. When we see any object, the light from that object travels through medium of air and reaches to our retina. The light has its specific wavelength and speed during its propagation. When an object is placed such that it is in two medium, the light travels from both the media before reaching our eye. Here the two media are air and water. Water has higher refractive index than air which causes refraction. Due to the change in medium the speed of light decreases. The refraction causes difference in speed of light the pencil like object kept in water appears to be bent or broken. .
