You walk into a room and notice that there someone is running an experiment involving a spring-mass system. You have no idea when the experiment started, but observe that the mass attached to the spring is oscillating with period 3 (seconds) and that the amplitude of the oscillations remain constant (to your naked eye) while you are in the room. What are two differential equations which model the motion of the mass? One system must be inhomogeneous and the other must be homogeneous. Do not worry about the initial conditions.

Let suppose you roll a die, and it falls into a hidden place, for example under furniture.
Then although the experiment has already been made (the die already has a number to show), that value can not be known, so the experiment was not fully realized.
Then till you see the die's top side, the probability remain p = 1/6.
I see no difference between this and the wave function collapse, at least as an analogy.
Can someone explain a deeper difference?

(Analysis of Transactions' Effect on SCF) Each of the following items must be considered in preparing a statement of cash flows for Cruz Fashions Inc. for the year ended December 31, 2020.

• 1.Fixed assets that had cost $20,000 6½ years before and were being depreciated on a 10-year basis, with no estimated scrap value, were sold for $4,750.
• 2.During the year, goodwill of $15,000 was considered impaired and was completely written off to expense.
• 3.During the year, 500 shares of common stock with a stated value of $25 a share were issued for $32 a share.
• 4.The company sustained a net loss for the year of $2,100. Depreciation amounted to $2,000 and patent amortization was $400.
• 5.Uncollectible accounts receivable in the amount of $2,000 were written off against Allowance for Doubtful Accounts.
• 6.Debt investments (available-for-sale) that cost $12,000 when purchased 4 years earlier were sold for $10,600.
• 7.Bonds payable with a par value of $24,000 on which there was an unamortized bond premium of $2,000 were redeemed at 101.

Instructions

For each item, state where it is to be shown in the statement and then how you would present the necessary information, including the amount. Consider each item to be independent of the others. Assume that correct entries were made for all transactions as they took place.

The purpose of this project is to design an “optimal” paper airplane using a 2-factor factorial experiment (2k) approach. Students will initially perform a 1/8 fractional factorial experiment on a paper airplane design that contains 6 design parameters, each design parameter containing two possible factors.

Using the interaction effects from the fractional factorial experiment, students will select the best combination of design parameters to create the “optimal” paper airplane. Experiments will be performed to assess the performance of this “optimal” design.

Your objective is to maximize the flight time. This will be assessed using maximum average distance traveled by the airplane in four trials.

Materials and Equipment:

• • Paper of varying thickness
• • Scissors
• • Flat working surface
• • Ruler

Design parameters / factors:

1) Paper Type

2) Length of Wing

3) Width of Body

4) Length of Body

5) Wing Type (Angled or Non-Angled)

6) Paper Clip

Recommended Protocol:

Part A : Assembling and testing initial airplane designs; results will be concluded out of class using Minitab, Excel, etc.

Part B: Develop and test the new airplane design using results of DOE from week 1.

Procedure:

Part A: Creation of Initial Airplane

Eight paper airplane designs will be created as defined below. The designs will vary based on the 6 design parameters. Trials will then be performed to assess the performance of each design. The performance measure of interest is the average distance traveled by the airplane in four trials.

Determine the Number of Trials Required:

Knowing that the experiment is a 2k fractional factorial design; and that 1/8 of the number of trials is acceptable; and that there are 6 factors and 2 responses; what is the number of required airplanes which need to be created?

Plane Design:

As stated before, this experiment is a 2-factor factorial experiment. The only factors for this experiment are high and low level values/characteristics.

Recording Distances:

Knowing that 4 trials is acceptable, complete 4 runs with each airplane, then find the average distance covered by the airplane. Record these distances in a table for each model.

Determining Effects of Control Parameters:

Which control parameter or parameters had the greatest effect? And why?

Part B: Creation of Improved Airplane Design

Based on the most influential variables and the interaction effects, create the “ultimate” paper airplane. Re-run the experiment 4 times and note the distances. Conclude in the lab write-up the change you made to the airplane, and whether your resultant design effected the distance of your airplane.

Part 1: Programming – Income Tax Application

1.1 Problem Statement

Due to upcoming end of financial year, you are being called in to write a program which will read in a file and produce reports as outlined.

Inputs:

The input file called IncomeRecord.txt contains a list of Annual income records of employees in a firm. Each record is on a single line and the fields are separated by spaces. The names of the fields are:

Employee ID number - Integer 

Employee Last name - String 

Employee First Name - String 

Annual Income - Double

An example record may have the following form:

10001 Smith Will 30000

10002 Sivo Maika 100000

10003 Deo Amit 25000

Note: This is just sample data, there will be more records for the other employees.

1.2 Program Specifications:

Your program should be able to process the following commands. i.e. Program should provide user with the following menu

. I. Read employee data. (from file IncomeRecord.txt)

II. Print all employees’ data. (on a new Window/Form)

III. Calculate the income tax for all and store it in an array.

IV. Display the employee data including the income tax. (on a new Window/Form)

V. Exit program.

1.2.1 Explanation of each menu item.

1. Read employee data You must create and use appropriate arrays to retrieve all the information about employees from the file IncomeRecord.txt

2. Print all employees’ data. This menu item should open a new window/form and simply print the contents of the arrays created in suitable format on the screen. You must display all fields and records.

3. Calculate the income tax for all and store it in an array. For this assignment, to calculate income tax, a 5% tax rate applies across the board to all income amount. A message should be displayed at the end to indicate that the calculation was completed successfully.

4. Display employee data including Income Tax. Display the ID, last name, first name, annual income, and the income tax calculated for all employees. This information should be displayed in a new window/form.

Sample output based on the data provided above:

10001 Smith Will 30000 1500

10002 Sivo Maika 100000 5000

10003 Deo Amit 25000 1250

5. Exit program This is when program should end.

Splish Company began operations on January 2, 2016. It employs 8 individuals who work 8-hour days and are paid hourly. Each employee earns 11 paid vacation days and 7 paid sick days annually. Vacation days may be taken after January 15 of the year following the year in which they are earned. Sick days may be taken as soon as they are earned; unused sick days accumulate. Additional information is as follows.

Splish Company has chosen to accrue the cost of compensated absences at rates of pay in effect during the period when earned and to accrue sick pay when earned.

Prepare journal entries to record transactions related to compensated absences during 2016 and 2017.
