A 64.7-kg skateboarder starts out with a speed of 2.44 m/s. He does 119 J of work on himself by pushing with his feet against the ground. In addition, friction does -257 J of work on him. In both cases, the forces doing the work are non-conservative. The final speed of the skateboarder is 7.88 m/s. (a) Calculate the change (PE_f - PE₀) in the gravitational potential energy. (b) How much has the vertical height of the skater changed? Give the absolute value.

Changes in Accounting Principle

Gaubert Inc. decided in March 2017 to change from FIFO to weighted-average inventory pricing. The company reported 2017 income as $30,000. Gaubert’s pre-tax income, using the new weighted-average method in 2015 would have been $35,000 ($5k higher than reported).

In 2016, if the new inventory method had been used, Income would have been $27,000 ($3k higher than reported).

What is the proper disclosure of this event?

Changes in Accounting Estimate

Arcadia HS, purchased equipment for $510,000 which was estimated to have a useful life of 10 years with a salvage value of $10,000 at the end of that time. Depreciation has been recorded for 7 years on a straight-line basis. In 2017 (year 8), it is determined that the total estimated life should be 15 years with a salvage value of $5,000 at the end of that time.

Calculate the depreciation expense for 2017

Correction of Errors

In 2018, Hillsboro Co. determined that it incorrectly overstated its accounts receivable and sales revenue by $100,000 in 2017. In 2018, what is the adjusting journal entry in order to correct for this error (ignore income taxes)?

Need urgently, please do it as soon as possible i have only 40 min for this task ( Doing in Java).

Question no 1: Solve completely.

a) Define the following concepts with proper syntax, where required. Also, write why we use these concepts (for last three bullets).

 Execution process of java program

 Copy constructor

 Instance and class variable

 Access specifiers

b) Write a program to print the area of a rectangle by creating a class named 'Area' having two methods. First method named as 'setDim' takes length and breadth of rectangle as parameters and the second method named as 'getArea' returns the area of the rectangle. Length and breadth of rectangle are passed through constructor.

Consider the cell described below at 251 K:

Pb | Pb²⁺ (1.47 M) || Fe³⁺ (2.11 M) | Fe

Given the standard reduction potentials found on the sheet attached to the exam, calculate the cell potential after the reaction has operated long enough for the [Fe³⁺] to have changed by 1.078 M

The use of assistive technology has had a huge impact on disabled individuals. Please discuss the benefits, as well as some potential issues, in the application of assistive technologies with this population. Include your operational definition of assistive technology in your response.

Thank you.

3. How is the purchasing and receiving function supposed to work for the Food and Beverage category – i.e., how is it designed to operate? What steps are different from the other categories? Again, a process flow map is helpful along with a specific example of something they might buy (i.e., salmon from Alaska or oranges from CA). Be sure to include the relationship with Safeway and how that works.

Find a 13-bit burst error polynomial that cannot be detected by the CRC-8 check. The burst error polynomial must have the form E(x) = x^12 + … + 1, and the terms x^k for k = 1, 2, …, 11 can have a coefficient of either 0 or 1. Here is a 13-bit burst error polynomial that can be detected: x^12 + x^8 + x^2 + x + 1. The CRC-8 generator polynomial is x^8 + x^2 + x + 1. (By a 13-bit burst error we mean that there has been a burst of energy that causes noise on the communication channel during the span of 13 bits. For example, the energy may drive the voltage to a high value for all 13 bits. Some of those bits might have been 1’s (and represented by the high voltage), so the energy does not cause those bits to be in error. So, assume the first and thirteenth bits are incorrect, and the bits in between those two end points may or may not be in error.)

1. You are the director of operations of a large airport. Discuss the above statement showing how far it is reflected in your day to day work. 2. The Information Super-highway is widely used in modern airports. Discuss how the Information Super-highway is useful in the following domains: a) Communication b) Security

We want to develop a sales system for a mobile shop. The system should keep information about the mobile phones available at the shop. the system should allow the user the ADD new mobile phones, one at a time, along with their features. The system should also allow to search mobile phones , update their information, and delete them (one by one). Try to provide different criteria for search. When the system starts, it should load the information about the mobile phones forma file. if the file doesn't exist, the system should create the file. The system should provide a (console based) menu to interact with it. The system not use any arrays and all the changes should be reflected in the file.

Describe the three main types of referential actions (cascade, restrict, set null). How do you use these in your work?

I have a problem with the code for my project. I need the two clients to be able to receive the messages but the code I have done only the server receives the messages. I need the clients to be able to communicate with each other directly not throught the server.

The requirements of this "local chat" program must meet are:

1. The chat is performed between 2 clients and a server.

2. The server will first start up and choose a port number. Then the server prints out its IP address and port number.

3. The client then will start up and create a socket based on the information provided by the server.

4. Now the client and the server can chat with each other by sending messages over the network.

5. The client/server MUST be able to communicate with each other in a continuous manner. (e.g. One side can send multiple messages without any replies from the other side)

6. There is no requirement on what language you use to implement this project, but your program should call upon the socket API for UDP to realize the functionality.

7. You should demonstrate your project using two machines (one for the client and one for the server. Pick your virtual machine as the client to communicate with your actual machine, which is server in our project).

8. You need to open at least 2 cmd window in your virtual machine to demonstrate multiple machine communicate with your server machine (actual machine)
