C++ language, only math equation, no code.

A Box on a slope slides under the following force F = m*g*sin(theta) - 0.2v(t). Assume m = 1kg and g=10 and theta = 30'. We want to simulate the slide using dt = 0.1 second interval. This means update frame rate is 10 per second. Initial speed is 0. After 2 seconds we like to know what is the current position and speed of the box. We want to do this using Explicit Euler(EE), Semi-Explicit Euler(SE), and Verlet Method for updating at each frame.

a) What are the update equations for EE method?

b) What are the update equations for SE method?

c) What is the update equation for Verlet method? How do you choose the initial first 2 positions in this method?

d) Provide a table showing updates per frame for each method. This means there are 3 columns, one for each method, and there are 20 rows for 20 frames to comprise 2 seconds of updates. Which method is more out of sync with the other 2 methods?

e) What is the maximum speed of decent of the box on the slope? why? (hint. Use analytical way to argue what is the maximum speed)

In C++, please build a simple Distance Vector program that will communicate with N partners and do the following. (NOTE: All connections between a server and clients should be TCP/IP socket.)

1. You will run N instances on your machine
2. Each instance will run on a different port (instance 1 will run on port 18181, instance 2 on port 18182, instance 3 on port 18183, etc)
3. The program will start by reading in the appropriate neighbors file and vector file.
4. The program will ONLY read vectors where the fromNode is equal to that node. For instance, node 1 will only read in vectors where node1 is the fromNode.
5. The program will support the following requests from clients:
   1. Show files at the server’s current directory: ‘print’
      1. This will print the current vector table on a node.
      2. ONLY print valid vectors (don’t print uninitialized ones)
   2. Download files: ‘refresh’
      1. This will force the current node to send its vector table to all its neighbors.
   3. Upload files: ‘update’

1. This will be of the form: Update fromNode toNode cost
2. Update checks that the toNode is the current node. If it is not it is ignored
3. Update then checks if the toNode-fromNode exists in vector table. If it does not it is added and neighbors are notified
4. If the pair is in the table, and if the new cost is less than the old cost, that cost is stored and the neighbors are notified.

the following information is relevant:

1. at the date of acquisition, the fair value of sontic's assets were equal to their carrying amounts with the exception of an item of plant which had a fair value of $2 million in excess of its carrying amount. it had a remaining life of five years at the date (straight line method depreciation is used) sontic has not adjusted the carrying amount of its plant as a result of the fair value exercise

2.sales from pretice in the post acquisition period were $8 million sontic made a mark up on cost of 40% on these sales. prentice had sold $5.2 million (at cost to prentice)of these goods by 30 September 2017. 3. sontic's trade receivables at 30 September 2008 include $600000 due from prentic which did not agree with prentic's corresponding trade payables. this was due to cash in transit of $200000 from prentice to sontic, both companies have positive bank balance

3.other than where indicated , statement of profit or loss items are deemed to accrue evenly on a time basis 5. prentice has a policy of accounting for any non controlling interest at fair value . the fair value of the non controlling interest at the acquisition date was $5.9 million

You are asked to design a relational database for a simple course registration software application for your school. The relational database must have the following information about the student, the course, and the registration, respectively

1. StudentID, FirstName, LastName, DataOfJoining, and Major
2. CourseNumber, CourseName,InstructorName, StartDate, EndDate, NumberOfCredits
3. ReferenceID, StudentID,CourseID, DateOfRegistration

Apply the following constrains while designing the database

1. Each student in the database must be uniquely identifiable
2. Each course listed in the database must be have unique CourseNumber
3. Each course registration must have unique ReferenceID.

A student can take multiple courses, but each course must be registered separately, and the following two rules must be applied

1. A student can do multiple course registrations
2. There can be many courses and a course can appear multiple times in the registration process.

Using pen and paper draw an Entity Relations Diagram (ERD) for the above application, then take a picture of it and submit. You may follow the below Steps for completing this assignment

Step 1: Identify the entities and their attributes involved in the given business.

Step 2: Write the entity names and their attributes along with the data type as tables.

Step 3: Identify the primary key fields and mark them as PK.

Step 4: Read and understand the business rules. Then, create natural relations between

entities that can capture the business rules. Identify the foreign key fields and mark them as FK.

Create an application to simulate a bank ATM and you must combine graphical interfaces using Swing or AWT and relational databases.

We will have a Bank Accounts database. Each account will have an account number, the name of the owner and the account balance.

The program must allow the following options:

a) Create an account: request the account information and save it in the database.

b) Enter the ATM: it will allow you to request the account number and will go to the next part of the program.

c) Close an account: delete it from the database

d) Exit

The second part of the program will perform the typical tasks of an ATM. It must perform the following:

a) See the account balance: Display the balance of the account. (The account has already been previously registered)

b) Deposit a money in the account: request the value to deposit and increase the balance in that value.

c) Withdraw money: request the value to be withdrawn, and if there is sufficient balance, this balance decreases in the value to be withdrawn.

d) Transfer money to another account: request the number of the other account and the value to be transferred, and if the other account exists and the balance is sufficient, decrease the source account by the indicated value and increase the balance of the other account by The transferred value.

e) Exit.

The program must be written in Java and you can use a desktop database (Access or H2 or Derby or Sqlite or HSQLDB) or a client-server database (MariaDB, MySQL or PostgreSQL).

In your opinion, what role does culture play in international expansion by a corporation? Your journal entry must be at least 200 words. No references or citations are necessary.

Write a one-page paper describing, discussing, and analyzing LIFO and FIFO. Research and include other sources. Include a title page, reference page, in-text citations.
