Two identical metal spheres attract each other with a force of 7.00 × 10−6 N when they are 3.00 cm apart. The spheres are then touched together and then removed to the original separation where now a force of repulsion of 2.00 × 10−6 N is observed. What is the charge on each sphere after touching and before touching?

Using a table of standard electrode potentials, decide which of the following statements is completely true.

A. Cu2+ can oxidize H2, and Fe can reduce Mn2+ .

B. Ni2+ can oxidize Cu2+, and Fe2+ can reduce H+ .

C. Fe2+ can oxidize H2, and Fe2+ can reduce Au3+ .

D. Br2 can oxidize Ni, and H2 can reduce Mn2+ .

E. H + can oxidize Fe, and Ni can reduce Br2.

Answer: E.. but why? can you explain why A-D are incorrect and why E is right. I know it has something to do with how they are positioned on the standard reduction potential list, but I dont understand the concept, which I will need to know for my exam. thank you!

The State Patrol Ticket Processing System

The purpose of the state patrol ticket processing system is to record driver violations, to keep records of the fines paid by drivers when they plead guilty or are found guilty of moving violations by the courts, and to notify the court that a warrant should be issued when such fines are not paid in a timely manner. The system does not maintain data on accidents, insurance, driving history and driver's licenses. These data are managed in separate systems and can be accessed by the State Patrol ticket processing system.

The data used by the ticket processing system involves driver data, officer data, and court data. The system creates and maintains ticket data. Driver data used includes license number, name, address, date of birth, date licensed, and so on. Court and officer data include the name and address of each respectively.  Ticket data created includes ticket number (each is unique and preprinted on each sheet of the officer's ticket book), location, ticket type, ticket date, ticket time and fine amount. Data related to ticket processing such as trial (plea date, trial date, verdict, fine amount), payment (amount and date paid), and warrant (date, type) are also recorded.

Each driver may have zero or more tickets, and each ticket applies to only one driver.

Other System Requirements:

1. When an officer issues a ticket to a driver, the ticket is also entered into the system. A new ticket record is created.
2. The driver can pay the fine online using the ticket number.
3. In some cases, the driver claims innocence by requesting a trial online. The system will then looks up driver, ticket, and officer information, and sends a ticket details report to the appropriate court.
4. The court schedules a trial date and notifies the driver of the date and time.
5. When the trial is completed, the court sends the verdict to the ticketing system. The verdict and trial date are recorded for the ticket. If the verdict is innocent, the system that produces driving record reports for insurance companies will ignore the ticket. If the verdict is guilty, the court informs the driver the amount of fine.
6. If the driver fails to pay the fine within the required period, the ticket processing system produces a warrant request notice and sends it to the court. What happens then is in the hands of the court.

Tasks:

1. Develop a DFD diagram 0 for the use case based on the narratives. Diagram 0 should include major processes in the use case. Group use case steps into a few processes (for example, three or four). Do not model each step. No child diagrams needed.   
2. Develop an Activity diagram for the use case based on the narrative.

Suppose you purchase a ten-year bond with 6 percent annual coupons. You
hold the bond for four years, and sell it immediately after receiving the fourth
coupon. If the bond's yield to maturity was 4.5% when you purchased and 7%
when you sold the bond. What is your annual rate of return on the bond in
each of the following situations:
a) All coupons were immediately spent when received.
b) All coupons were reinvested in a bank account, which pays 2 percent
interest until the bond is sold.

The bubble sort described in AS 7e is inefficient when perform on a larger array. To improve the efficiency, we have to observe the basic mechanism of Bubble Sort.

Each inner loop of the Bubble sort always move the largest item on the unsorted left side to the sorted right side.

When a list is sorted, we say the list is in ascending order by convention.

We can enhance the efficiency of traditional Bubble sort by making only one swapping per inner loop iteration. To accomplish this, the following simple modifications are applied:

1. The inner loop is to find the index of the largest item inside the unsorted region.
2. The outer loop is to swap the largest item with the rightmost unsorted item, and then the right most unsorted item becomes the newest sorted item.
3. The array started as one big unsorted region; each inner loop iteration move one unsorted item to become a sorted item.
4. The number of comparisons is the same as the standard bubble sort, however, the number of swaps are reduced to no more than once per inner loop and no more than n times for the entire sort.

Hint:
The inner loop finds the index of the largest item of the unsorted region and performs no swap operation.
The outer loop index to track the range of "unsorted region."

Example of Sorted vs Unsorted region through each inner iterations:

4, 3, 5, 7, 2, 9, 1  unsorted | sorted

4, 3, 5, 7, 2, 1| 9 (1st iteration)
4, 3, 5, 1, 2| 7, 9 (2nd iteration)
4, 3, 2, 1| 5, 7, 9 (3rd iteration)
1, 3, 2| 4, 5, 7, 9 (4th iteration)
1, 2| 3, 4, 5, 7, 9 (5th iteration)
1, 2, 3, 4, 5, 7, 9 (6th iteration)

Designing and implementing a C++ structure data type - Monthly Budget

Remember to use correct code formatting and documentation.

A student has established the following monthly budget:

Budget Categories       Budgeted amount

-----------------------------------------------------

Housing                  $ 580.00

Utilities                   $ 150.00

Household Expenses    $ 65.00

Transportation           $ 50.00

Food                      $ 250.00

Medical                  $ 30.00

Insurance                $ 100.00

Entertainment           $ 150.00

Clothing                  $ 75.00

Miscellaneous           $ 50.00

----------------------------------------------------

Write a program that declares a MonthlyBudget structure designed with member variables to hold each of these expense categories. The program should define two MonthlyBudget structure variables budget and spent. The first MonthlyBudget structure variable budget will contain (ie., be assigned) the budget figures given above. Pass this first structure >budget variable to a function displayBudget that will display the budget categories along with the budgeted amounts.

The second MonthlyBudget structure variable spent will be passed to another function getExpenses that should create a screen form that displays each category name and its budgeted amount, then positions the cursor next to it for the user to enter the amounts actually spent in each budget category during the past month.

Finally, the program should then pass both structure variables budget and spent to a function compareExpenses that displays a report indicating the amount over or under budget the student spent in each category, as well as the amount over or under for the entire monthly budget.

You may design your own user-input interface but you must use a structure and must implement the three functions listed above. The format of the monthly budgeted report should appear as similar as possible to the sample output shown below.

HINT: Use the setw and right manipulators to right-justify dollar value outputs in function compareExpenses.

INPUT VALIDATION: Do not accept negative values for the users actual expenditure inputs in function getExpenses.

A sample test run using the Code::Block IDE-CompilerHere is your monthly budget for YEAR 2020:

Please make sure to declare your struct above your function prototypes and include appropriate function documentation as needed. You may use pointers or constant reference parameters when passing the structure variables to the functions mentioned above. DO NOT use global variables.

Your assignment for this program is to evaluate a numeric expression in postfix notation using a dynamic (pointer based) stack. As stated in the handout, in order to evaluate a numeric expression, a compiler converts an infix numeric expression to postfix notation and then it uses an algorithm and a stack to evaluate the expression. Your program should implement the pseudocode algorithm described in the attached handout.

Your program will read and evaluate expressions stored in an input file (infile.txt). The process will continue until the end of file is read. After each expression is read and evaluated, the expression and its value should be output to a text file using the following format.

                        EXPRESSION: XXXXXXXXXXXXXXXXXXXXXXXXXXX

                        VALUE:XXXXXX

You may assume all expressions in the file will be in postfix notation. You may also assume that the expressions will only have the following operators: +, -, *, /. The variables found in the expressions will be either A, B, C or D. No other variables will be used. The variables should be assigned the following values in your program:

                                    A = 14.0, B = 16.0, C = 20.0, D = 30.0

Assume that all variables will be uppercase. You may store the expression in a string and extract one character at a time. Please use the data file shown below for the program run.

Output your run to another file.

Please note: Your stack should include a working destructor.

infile.dat

DCA-+

ABC-+

ABCD*+A/-

AB-CD+*

Hint: You can use this code to help you input the string and process each character in the string.

while(!in.eof()){

            in>>s; // s is a string, read the entire string on the line

                // process each character in the string using s.length() and a for loop

            for (int i = 0; i < s.length(); i++)

                    //check to see if the character is an operator (+,-,*,/)

                    // or operand A,B,C,D

                    if(s.substr(i,1)==                  ) // use the handout algorithm for the rest

    }

Given s, declared as a string then s.length() returns the number of characters in the string; s.substr(i,1) returns the character in the ith position of the string. The string library contains the length and substr methods; substr(i,n), another method, will return n characters starting at position i of a string.
