A simple way to model air pollution over a city is with a box model that assumes complete mixing and limited capability for the pollution to disperse horizontally or vertically except in the direction of the prevailing winds. An example is a town located in a valley with an inversion layer above it that prevents vertical convection. This inversion is at an altitude of 0.25 km. There is a wind entering the town at a speed of 2.00 m/s; the town is 20.0 km wide perpendicular to the wind and 25.0 km long in the direction of the wind; carbon monoxide is being emitted in the town at a constant rate of 60.0 kg/s. Assume the carbon monoxide has a decay rate coefficient of k = 0.10/hr. What is the steady-state concentration of cartoon monoxide in the town (in ppmv)? Suppose a nearby storm passage causes the wind speed in the town to suddenly to 10.0 m/s. What is the carbon monoxide concentration two hours later? Solution steady state concentration of carbon monoxide is =60/25 =2.4 one hour late the concentration will be zero....... .

A simple camera telephoto lens consists of two How far behind the concave lens should the film be placed? Express your answer using two significant figures concave lens with a focal length f210.1 cm The object to be photographed is 4.01 m in front of the objective lens. cm Submit Part B What is the linear magnification of this lens combination? Express your answer using two significant figures. Solution The image from the first (convex) lens is formed at a distance i1 from the object 1/o1 + 1/i1 = 1/f1 1/401 + 1/i1 = 1/39 i1 = 43.2 cm This image is formed 43.2 - 36.0 = 7.2 cm behind the second lens. That becomes the virtual image of the convex lens at i2 = -7.2 cm. The object for that image is 1/o2 + 1/i2 = -1/f2 1/o2 - 1/7.2 = -1/10.1 o2 = 25.1 cm o2 is actually the image of the lens system (interchange object and image in the concave lens formula). Image i1 has magnification 43.2/401 = 0.108, and the image i2 has magnification 25.1/7.2 = 3.5. Overall magnification is 0.108*3.5 = 0.378 .

A priniciple purpose of a representation letter from management is to: Solution Management representation is a letter issued by an auditor\'s client to the auditor in writing as one of audit evidences. The date of the document must not be later than the date of audit work completion. It is used to let the client\'s management declare in writing that the financial statements and other presentations to the auditor are sufficient and appropriate and without omission of material facts to the financial statements, to the best of the management\'s knowledge. it is a form letter written by a company\'s external auditors, which is signed by senior company management. The letter states that all of the information submitted is accurate, and that all material information has been disclosed to the auditors. The auditors use this letter as part of their audit evidence. The letter also shifts some blame to management, if it turns out that some elements of the audited financial statements do not fairly represent the financial results, condition, or cash flows of the business. .

A process or task in Linux is represented by a Answer data structure. Solution Linux can manage the processes in the system, each process is represented by a task_struct data structure (task and process are terms that Linux uses interchangeably). The task vector is an array of pointers to every task_struct data structure in the system. Each process on the system is in exactly one of five different states. This value is represented by one of five flags: TASK_RUNNING: The process is runnable; it is either currently running or on a runqueue waiting to run.This is the only possible state for a process executing in user-space; it can also apply to a process in kernel-space that is actively running. TASK_INTERRUPTIBLE: The process is sleeping (that is, it is blocked), waiting for some condition to become true or a signal is received. When this condition exists, the kernel sets the process\'s state to TASK_RUNNING. The process can awake and become runnable if it receives a signal. TASK_UNINTERRUPTIBLE: This state is identical to TASK_INTERRUPTIBLE except that it does not wake up and become runnable if it receives a signal. This is used in situations where the process must wait without interruption or when the event is expected to occur quite quickly. Because the task does not respond to signals in this state, TASK_UNINTERRUPTIBLE is less often used than TASK_INTERRUPTIBLE6. TASK_ZOMBIE: The task has terminated, but its parent has not yet issued a wait4() system call. The task\'s task structure must remain in case the parent wants to access it. If the parent calls wait4(), the task structure is deallocated. TASK_STOPPED: Process execution has stopped; the task is not running nor is it eligible to run. This occurs if the task receives the SIGSTOP, SIGTSTP, SIGTTIN, or SIGTTOU signal or if it receives any signal while it is being debugged. .

Crystal clear water sports has 14,000 shares of $1 par value common stock outstanding. Crystal Clear distributes a 10% stock dividend when the market value of its stock is $20 per share. Journalize Crystal Clear\'s declaration of the stock dividend on July 15 and distribution on July 31. What is the overall effect of the stock dividend on Crystal Clear\'s total assets? What is the overall effect on total stockholder\'s equity? Solution Date Account heads Debit Credit 15-Jul To record declaration of stock dividend Retained earnings (14000 * 10% = 1400 * $20) 28000 Stock dividend distributable (1400 * 1) 1400 Paid in Capital in excess of par (1400 * 19) 26600 31-Jul To record distribution of stock dividend Stock dividend distributable (1400 * 1) 1400 Common stock account 1400 2. Unlike cash dividend, stock dividend involves no distribution of assets or liabilities. So, it has no effect on the Assets or Liabilities 3. Stockholders\' equity, also called owners\' equity, is the surplus of a company\'s assets over its liabilities. Cash dividends reduce stockholders\' equity by distributing excess cash to shareholders. Stock dividends distribute additional shares to shareholders and do not affect the balance of stockholders\' equity. Net worth (Share capital + retained earnings) is not affected. It is an inter change of Numbers between the two. Equity capital balance is increased and retained earnings balance is reduced .

Critical thinking question: what structural features (hint: there are four) do all ten of these opioid drugs have in common? Opioids Opioids are a powerful class of alkaloids that act on the central nervous narcotic analgesics. All opioids presumably bind to the same mu-opioid receptor sites in the brain and spinal cord. The most prevalent naturally occurring isolated from the opium poppy-is morphine (named after Morpheus, the sod of dreams). A methoxy derivative of morphine that is also isolated from opium poppy is codeine, which is both less addictive and less effective as a reliever than morphine. By contrast, the diacetyl derivative of morphine (heroin) isanalgesic not only a more powerful as a narcotic but also more addictive than morphine Many other synthetic derivatives of morphine are opioid agonists that are used as narcotic analgesics (including oxycodone, oxymorphone, hyd system as a plant-derived nitrogenout bases that have pronounced physiologial acevity on humans the arcotic a drug dhas numbs the ngonisa molecule that combines antagonist a molecule that inhibits senses and induces stupor a druE hat with a receptor to initiate and meperidine), while others (such as methadone and buprenorphine) are used to treat opioid addiction.

Create a polynomial function that meets the following conditions. Explain how you created your polynomial. 4. Degree 3, 2 positive real zeros, 1 negative real zero, 0 complex zeros. Polynomial: Solution Polynomial may be : f(x) = -x^3 + x^2 + x - 1 Reasoning : the number of positive roots of the polynomial is either equal to the number of sign differences between consecutive nonzero coefficients. so here has two sign change(the sequence of pairs of successive signs is -+, ++, +-). So it has 2 positive roots. for negative root we change the signs of the coefficients of the terms with odd exponents, i.e., apply Descartes\' rule of signs to the polynomial f(-x), to obtain a second polynomial f(-x) = x^3 + x^2 - x - 1 it has 1 sign change so f(-x) has one positive root so f(x) has 1 negative root. .

Contrast the argument that terrorist acts are easy to predict with the argument that they cannot be identified or predicted. Write it 4-5 paragraph with resources(References). Solution By using technology it was easy to predict the terrorist acts. This is because terrorists use social media sites for communication and now-a-days there are many pattern recognization and data mining algorithms are implemented to identify the words and to predict the next action of the terrorists reference:http://www.iflscience.com/technology/how-technology-help-predict-terrorist-attacks/ And even though advancement of technology cannot predict the terrorist act all the time, because if the terrorists are at one place then they don\'t use the internet or social media sites, so there will be no chance of prediction. But NSA, which have access to almost every device in the world can easily predict the action of every human being in the world and there are many other security agencies like NSA also can do this thing. Majorly, technology plays an important role in identifying or predicting the action of terrorists .

Constants Part A By measurement you determine that sound waves are spreading out equally in all directions from a point source and that the intensity is 2.7x10-2 W/m2 at a distance of 4.5 Im from the source What is the intensity at a distance of 3.5 m from the source? Express your answer using two significant figures W/m2 Submit Incorrect. Try Again; 6 attempts remaining Part B How much sound energy does the source emit in one hour if its power output remains constant? Express your answer using two significant figures Submit Solution Part A. Intensity is given by: I = P/A = P/(4*pi*r^2) Since Source is same at both distance, So Power is constant, which means intensity is inversely proportional to square of distance from source. I2/I1 = (r1/r2)^2 I2 = I1*(r1/r2)^2 I2 = 2.7*10^-2*(4.5/3.5)^2 I2 = 4.5*10^-2 W/m^2 Part B. Power of source will be P = I*4*pi*r^2 P = 2.7*10^-2*4*pi*4.5^2 P = 6.87 W Now energy is given by: E = Power*time E = P*t t = 1 hr = 3600 sec E = 6.87*3600 E = 24732 J = 2.5*10^4 J Please Upvote. .
