Silica gel is slightly acidic. Will this cause an acidic compound to run faster or slower in a given mobile phase vs a similar basic compound? Why? Solution SiO2 is an acidic compound.when SiO2 in water gives acid H2SiO3. In acidic or basic condition, mainly depends upon polarity. Polar compounds easily hydrogen bonding with silica gel and make highly mobile phase polar. Polar.compounds bind with silica gel easily whereas nonpolar compounds easily will come in the column chromatography..

The functions f_1, f_2, ..., f_m defined on the interval I are said to be linearly dependent on I if at least one of them can be expressed as a linear combination of the others on I. Equivalently, they are linearly dependent on I if there exist constants c_1, c_2, ..., c_m, not all zero, such that c_1 f_1 (x) + c_2 f_2 (x) + middot middot middot + c_m f_m (x) = 0 for all x I. Otherwise, they are said to be linearly independent on I. Show that the functions f_1 (x) = e^x f_2 (x) = e^-2x f_3 (x) = 3e^x - 2e^-2x are linearly dependent on (-infinity, infinity). Solution Given that f1(x) = ex , f2(x) = e-2x and f3(x) = 3ex - 2e-2x Then there exists non-zero constants C1 = - 3 , C2 = 2 and C3 = 1 such that C1f1(x) + C2 f2(x) + C1f3(x) = 0. Hence The functions f1( x) = ex , f2(x) = e-2x and f3(x) = 3ex - 2e-2x are linearly dependent for all x *( - , ).

Compare and contrast the main approaches for developing a WBS. Which approach do you feel is most user-friendly? Explain your answer. Solution The main approaches for WBS development are as follows: 1. Deliverable based approach: The project team works as per the functional components of the products. Here the process are compiled and accomplished as per the elements that constitutes the complete project. 2. Task Based: The tasks to create the project deliverable are first identified and are prioritized. This is also known as verb based method. 3. Time based: The projects are divided as per the completing and delivery time so that the projects that are to be delivered first can be worked upon by the team. 4. Cost based. The project is defined in terms of cost. The following methods are used for developing a WBS: 1. Top-Down Approach: The steps involved in the top-down process are as follows: This approach is appropriate when the project members are greenhorn to WBS development and the project\'s nature is complex and ambiguous. 2. Bottom-Up Approach: The steps involved in the bottom-up process are as follows: This method is applicable when the nature of the project, project scope, and life cycle is clear. Bottom-up method is more user friendly as the appropriate templates and organizational standards are available..

***please help! READ the grading criteria*** HW5: Weekly Timesheet CSS 161 Fundamentals of Computing By: Hansel Ong Summary In HW3, you created a program that allows the user to enter time worked on a week-by-week basis Such a system calculated any hours worked over 40 hours a week as overtime. However, this means that an employee could work 12 or 20 hours once a week, 4 hours the rest of the week, and not be paid overtime at all. Let\'s fix this problem in this homework. For simplification, let\'s limit the number of weeks the user can enter to two weeks maximum. Note also that any hours worked in a day beyond 8 hours should be regarded as overtime hours. Estimated Work Needed This assignment took me about 30-45 minutes to write (not including challenges, but including testing, commenting, and cleanup) in less than 200 lines of code In other words, you should expect to spend between 135 to 450 minutes working on this assignment. If you\'ve spent more than 7.5 hours working on this assignment, then you are likely struggling with loops and/or arrays and should re-read the lecture slides and attempt the exercises within seek help from your fellow classmates, myself, your lab instructor, QSC tutor as well as online resources. Skills Expected All the skills from previous Assignment(s) Arrays File I/O Assignment Description Write a program that does the following Provide the following \"main menu\" to the user (Create a method for each of the choices): o (1 point) Enter/Edit Timesheet o (1 point) Display Timesheet o (1 point) Print Paystub (End Program) o (1 point) Keep presenting this menu to the user until user asks to print a paystub For \"Enter/Edit Timesheet\" o (1 point) Ask the user which week the user would like to edit (1 or 2) (1 point) Return to \"main menu\" if user chooses anything other than 1 or 2 o (2 points) Display each day of the week (M, Tu, W and the number of hours worked for each day (display 0 by default until user has entered a value) (2 point) Allow the user to edit hours for specific days of the week (1 point) Return to \"main menu\" if user enters an invalid day of the week or invalid hours of the day Solution // Paystub.java import java.util.Scanner; public class Paystub { static int insuranceDeduction = 25; static int regularHours1 = 0; static int overtimeHours1 = 0; static int regularHours2 = 0; static int overtimeHours2 = 0; static int[] week1 = new int[7]; static int[] week2 = new int[7]; public static int mainMenu() { System.out.println(\"\ \ --------------Main Menu----------------\"); System.out.print(\"1.

In 1972 the small kingdom of Bhutan, in Asia, developed a measure of output that included “Happiness.” In class we also saw that former Senator Robert F. Kennedy criticized GDP for its inability to take into account the quality of life of a nation’s citizens. In 2013, President Obama has appointed you to look into developing a new measure of the nation’s overall economic well- being called the Gross Domestic Happiness Indicator (GDHI). What would you include in this new measure and how will you incorporate existing measures of GDP into the GDHI? Solution Ans I will include Gdp per capita, measures of social support, life expectancy at birth, corruption and nepotism, freedom to choose,pollution, public goods, environmental goods in thus measure. Gdp per capita is the existing measure that I will utilize..

How do you do the last page?. How do you make the picture with the trail. I\'ve coded everything but that need help with how to change the numbers in the matrix to produce the correct trail. Coded in C please. How Do u code the function ask of on the last page? CS 100 Project Six-Fall 2016 Project Ovenicy: The world is not flat, despite what the Flat Earth Society hupsLAww:a.theflatearthsociety.org) says. There are lots of hills and valleys out there. Given this, mankind has spent considerable time and effort measuring the exactelevation above sea level for each on the earth You can view these elevation maps as a two- dimensional grid. A sample elevation shown below: 100 110 120 105 115 100 105 115 110 100 105 115 95 120 120 98 95 110 125 130 135 100 110 120 130 135 145 Obviously, elevations get higher in the mountains, and approach zero as you near the ocean. This program reads a set of elevation data and: 1. Generates a simple image from this clevation data, a black-and-white image where higher clevations have a darker shade than lower elevations. 2. Identifies a path across this grid. The path can be North-to-South, South-to-North, East-to-West, or West- to East. To find this path, you vant to minimize your clevation gain (climb). In other words, you don\'t want to walk uphill any more than necessary. Instead, you want to go as much as possible, a steep downhill path is viewed as optimal. You will generate a second image file with the recommended trail. To generate a black-and-white (grayscale) picture of this elevation data, we will use a graphics format that uses ASCII (text files. Most graphics programs use binary files (gif,jpeg, etc) which promote smaller fle sizes. Since this is just CS 100, well stick with ASCII (text) files, even though they take more space. The ASCII format we use is called pgm, and is shown P2 at the right. The first line is always P2. After that, you width inpix have three values (width, height, grayscale levels that pixels value (always 2SS for this project) maximum grayscale can be on a single line or separate lines. Finally, you pixel-11- intensity pixel-1-2-intensity pixel-1-3-intensity have the actual pixel values for each pixel in the image. pixel-2-1-intensity pixel2-2-intensity pixel-2-3-intensity A pixel with a value of 0 is black (absence of light and a pixel with a value of 255 is white (all light pielN-1 intensity pixelN-2- intensity pixel-N-3intensity This project involves taking a set of elevations and making a grayscale image from these elevations, and then drawing a second image that includes a trail across the grid. You are crcating two PEm images. Both of these images will use 255 as the maximum grayscale value (values range from 0-255) The first image is simply a map of the clevations. So that we can mark a visible trail on this map part two), we will map all the clevations in our input file to a value in the range of 55255. By doing this, placing a trail of color 0 (black) is easily visible o.

How do auditors gain an understanding of the internal controls in an IT environment? Solution The control environment is the foundation on which an effective system of internal control is built and operated in an organization that strives to (1) achieve its strategic objectives, (2) provide reliable financial reporting to internal and external stakeholders, (3) operate its business efficiently and effectively, (4) comply with all applicable laws and regulations, and (5) safeguard its assets. Most of the well-publicized failures (including not only Enron and WorldCom, but also the governance failures that led to the 2008 financial crisis) were, at least in part, the result of weak control environments. The control environment includes the following elements: • Integrity and ethical values. • Management philosophy and operating style. • Organizational structure. • Assignment of authority and responsibility. • Human resource policies and practices. • Competence of personnel. Central to any approach to auditing the control environment is the assessment of risks from failure of each one of the six individual control environment elements as defined in the glossary of the Standards. Upon determining the risks relating to each one of the six control environment elements, the chief audit executive (CAE) may consider including in his or her annual audit plan one or more failures can miss the fundamental aspects of the organization’s foundation..
