You are told to move charge Q a distance of 1.0 m so as to cause the greatest increase in its electrical potential energy. In which direction do you move it? b. What is the electric field 0.10 m from a point charge Q1 which carries a charge of 0.20 ?C? x 10P N/C away from Q1 C. What is the initial acceleration of an electron when placed in an electric field at a point where the electric field strength is 6.7 x 105 N/C? A/ x 1017 m/s2 d. 10.0 m 6.0m - The electric field at point P in the diagram is 8500 N/C directed to the right. What is the size and polarity of charge q2? Solution here, a) the electrical potential energy , PE = k * q1 * q2 /r q1 - fisrt charge q2 - seccond charge r - sepration between the charges for maximum increase in potential energy the change in distance between the charges must be decreased the charge Q must be moved along the line 4 .

John Corporation has three investments that are classified as noncontrolling. 1.A bond investment, purchased on Jan 1, 2014 and maturing on Dec. 31, 2020. They purchased them to help out the company and the interest income was quite high. 2. An investment in Mark Company stock, purchased on Dec. 1, 2014 because the price was low and John Corp. had some excess cash to invest. John Corporation\'s investment manager did not like taking risk or playing the market on an active basis. 3. An investment in 25% of the stock of Smith Company, a new customer who was experiencing management difficulties that affected their profitability. John Corp. intended to keep this investment for as long as it took to stabilize the company. Answer the following questions about these investments. 1. The investment in bonds should be classified as: Select one: a. held-to-maturity securities b. trading securities c. significant influence securities d. available-for-sale securities 2. The investment in Mark Company stock should be classified as: Select one: a. trading securities b. available-for-sale securities c. significant influence securities d. held-to-maturity securities 3. The investment in Smith Company stock should be classified as: Select one: a. held-to-maturity securities b. trading securities c. available-for-sale securities d. significant influence securities Solution Bonds are d. available-for-sale securities Reason is that they were bought to help out other company rather than making money out of it. Investment in Mark company is reffered to as d. held-to-maturity securities Investment in Smith Company is reffered to as d. significant influence securities as these stocks amount to 25%. Stock holing of 20 to 50% is refferef to as Significant influence securities. .

John Smith worked in the stockyard of a large building supply company. One day he unexpectedly left for California, never to return. His foreman seized the opportunity to continue to submit time cards for John to the payroll department. Each week, as part of his normal duties, the foreman received the employee paychecks from payroll and distributed them to the workers on his shift. Because John was not present to collect his paycheck, the foreman forged John Solution In the given circumstances, these two internal controls can be implemented to prevent & detect fraud- 1. The practice of giving paychecks to the foreman should be done away with. Instead each employee should personally visit the payroll department, put his signature and then collect his or her paycheck. 2.For attendance purpose also the employees should visit the payroll department where the time keeper will personally accept each one\'s time card. Time card furnished through a colleage or friend should never be accepted. .

John has tremendous technical skills and frequently comes up with valuable ideas. However, he has little idea how to promote it within the organization. John is a good example of a. an inventor. b. an idea champion. c. a sponsor. d. a critic. e. an in-transition employee. Solution a. Inventor is the one who develops and understands technical aspects of idea. Inventor has no knowledge or less knowledge of converting the idea into a business. Though John has a tremendous technical skills but he has little knowledge of promoting the idea. Thus, he is an INVENTOR. .

Joe Frecaso was recently hired as the controller for Larson Cement Company after the previous controller was killed in a boating accident in Biscayne Bay. That controller had been with the company since it first opened its doors. Joe spends most of his time in the back office that has a panoramic view of Solution 1. Frank and Joe have realized that the checks payable to Mary Waters is being done fraudently. Betty is responsible for the checkbooks and she keeps the checkbook locked in safe. So it is quite clear that Betty has been fraudently writing the checks being paid to Mary Waters and Frank and Joe are quite on target at this assumption. However, they could do better by confronting Betty and initiating a legal suit against her for causing losses to the company. They should be more aggressive and action-oriented than just putting a camera at her office and conducting an audit. She should be immediately confronted, enquired upon and if found guilty of these wrong doings should be immediately fired. Subsequently, legal action should be taken against her. 2. Clearly the internal control processes is quite weak at Larson\'s Cement. Joe, as the controller, should be knowing the accounting and finance department\'s workings in and out. However, he was shocked to learn about the account being overdrawn. Its just Frank, the current CEO, who seems to be hands on. Other employees also need to be more hands on, specially Joe who is responsible for the company\'s control process. Its no excuse that Betty is responsible for the checks, so she should be the only one having information about them. This is a clear gap in the control system of the company, inviting wrong doings by the employees. This gap needs to be filled. .

Java Write a method that takes as a parameter a one dimensional array of characters and moves all characters â€™*â€™ to the end (high indexes) of the array. If the original array is â€™aâ€™ â€™bâ€™ â€™*â€™ â€™dâ€™ â€™zâ€™ â€™*â€™ â€™*â€™ â€™pâ€™ then your method should produce â€™aâ€™ â€™bâ€™ â€™dâ€™ â€™zâ€™ â€™pâ€™ â€™*â€™ â€™*â€™ â€™*â€™ The relative positions of the other characters should remain unchanged. REMEMBER : Write a complete method (including methods signature with parameters and return type). DO NOT write a complete program with main, etc. Your method should manipulate the array that is passed to it. Solution public class MoveStar { public static void moveStar(char[] arr){ if(arr == null) return; int j = -1; for(int i=0; i<arr.length; i++){// skipping star if(arr[i] !=\'*\'){ arr[++j] = arr[i]; } } while(++j < arr.length)// filling remaining position with * arr[j] = \'*\'; } public static void main(String[] args) { char[] arr = {\'a\', \'b\' ,\'*\' ,\'d\' ,\'z\',\'*\', \'*\' ,\'p\'}; moveStar(arr); for(char c: arr) System.out.print(c+\" \"); } } .

For each pair of substance identify the substance that is likely to have the lower vapor pressure. Using IMF to explain your reasoning. a. CO 2 or XeF 2 b. CH 3 OH or CH 3 -O-CH 3 Solution Always remeber VAPOUR PRESSURE TENDS TO DECREASE AS THE INTERMOLECULAR FORCES INCREASES. a. CO 2 and XeF 2 both are non polar but in case XeF 2 there are more lone pairs on the central atom which cause lone pair-lone pair repulson and bonds are easily broken so XeF 2 will have less intermolecular force of attraction while CO 2 having low vapour pressure as double bonds are holding 2 oxygen atoms to carbon atom having higher intermollecular force so CO 2 will have low vapour pressure. b.CH 3 OCH 3 will have the higher vapor pressure. . CH 3 OH can hydrogen bond. CH 3 OCH 3 is polar (bent shape around the oxygen), so dipole-dipole forces will be the strongest forces in this compound. .

For Contingent Liability: When do you disclose it? When do you record it? When do you ignore it? Solution Contingent liabilites can be divided into three classifcations: -Remote - There is a remote possibility that this will become a liability. A perfect example of this would be a frivolous lawsuit filed against your company with no sound legal reasoning. Those that are remote should be ignored. -Possible - It is possible for this to become a liablity, but possibly not during this accounting cycle. Many companies list these possible liabilites in the footnotes of their year-end financial statements, but are not show on any of the actual statments as a liability. If it is possible, it should be disclosed. -Probable - In this circumstance, the proposed liability is more than likely going to become a current or long-term liability. This may include an out-of court settlement where the company will be forced to pay a sum of money. Because it is probable, it should both be disclosed and recorded on the financial statements. Hope this helps! .

For each of the abstract data types (ADTs) that we have analyzed in this class we have implemented each of them in two different ways (Array-Based and Link-Based). Describe each of these implementations and discuss the differences between them. Solution Abstract data types can be implemented using array or linked list. but there are some major differences. linked list have some advantages over array. an array has some demerits. but a linked list overcomes all these demerits. Difference between Array Linked list : Array is a collection of homogeneous elements.it is a linear data structure. array have fixed size. once its size is declared, it cannot grow or shrink in size during execution. it has static memory of allocation. it stores data in contiguous memory locations. array is easily accessible. but it is difficult to perform insertion and deletion operations on an array.because during insertion or deletion each element after the specified element need to be moved one position right or left. Linked list is another way of storing elements in memory.it is a collection of data items called nodes. each node is divided into two parts called data field and pointer field. data field contains the element and pointer field contains the address of the next node in the list. the pointer field of the last node contains null value. it is a non-linear data structue. it doesn\'t require contiguous memory to store data in memory. it has dynamic memory of allocation. a linked list can grow or shrink in size during execution for its lifetime. the operations like insertion and deletion is easy to perform on linked list. because it stores data in non-contiguous memory location,so shifting of elements is not required. **************** THANKS ********************** PLS GIVE GOOD FEEDBACK********************************************* .

For each form of transport plot the value of overall benefits against cost and hence identify the forms of transport that lie on the efficient frontier Solution Of course, no matter what form a tax takes, it is still a transfer payment-whether a direct tax on income or an indirect tax such as a sales tax, an excise tax, or a tariff or duty on an imported input for production. But some caution is advisable here. Taxes that are treated as a direct transfer payment are those representing a diversion of net benefit to the society. Quite often, however, government charges for goods supplied or services rendered may be called taxes. Water rates, for example, may be considered a tax by the farmer, but from the standpoint of the society as a whole they are a payment by the farmer to the irrigation authority in exchange for water supplied. Since building the irrigation system reduces national income, the farmer\'s payment for the water is part of the cost of producing the crop, the same as any other payment for a production input. Other payments called taxes may also be payments for goods and services rendered rather than transfers to the government. A stevedoring charge at the port is not a tax but a payment for services and so would not be treated as a duty would be. Whether a tax should be treated as a transfer payment or as a payment for goods and services depends on whether the payment is a compensation for goods and services needed to carry out the project or merely a transfer, to be used for general social purposes, of some part of the benefit from the project to the society as a whole. .

Fluctuation in inflation can occur in the short or long term. For examle, rice levels can increase and decrease on a month to month aisis and we can also evaluate inflation rates over time. Therefore, while it may be hard to redict the economic change it can be tracked over different time periods. One way we can think about inflation is that because of a loss in purchasing ower, there is basically a lower payout to investors. Are there any investing strategies that can be taken in order to rotect against this risk? Solution Investing startegies that can be taken to protect against inflation risk:- 1) Investing smartly in all types of investements like shares, real estate and golds . It will reduce the risk of inflation. 2) Short term investement in stocks and booking the profit instead of long terms. 3) Bonds are the most sensitive in the inflation, we should be extra careful with that. 4) Investors should maintain the portfolio highly flexible and liquidable during inflation. .
