As defined in Chapter 7, the work done by a force on an object is equal to the force times the displacement times the cosine of the angle between the force and displacement vectors (W=F·d cos(θ)).
Suppose you are supporting a 1.56-kg block. What is the gravitational force (magnitude and direction) acting on the block?

If you lower the block a distance of 0.208 m, what is the work done by the gravitational force as you lower the block?

What is the value of the angle θ (in degrees – do not enter units)?

What is the change in the gravitational potential energy as you lower the block 0.208 m? (If the potential energy increases, the answer should be positive. If the potential energy decreases, the answer should be negative.)

Let’s switch gears and ask about the electrical force on a charged object. Suppose you have a region where the electric field has a magnitude of 23.1 N/C, the field points straight down, and the field is uniform (ie., the magnitude and direction are the same everywhere in this region). You place an object which has a charge of +0.251 C in this field. What is the magnitude and direction of the electric force acting on the object?

Suppose you lower the object a distance 0.208 m (in the same direction the field is pointing). What is the work done by the electrical force as you lower the block?

What is the change in electric potential energy as you lower the object 0.208 m? (If the electric potential energy increases, the answer should be positive. If the electric potential energy decreases, the answer should be negative.)

Although “it is impossible to prepare a response to something that has not been considered in advance”, still we work on resilient engineering as, a system is resilient to the degree to which it rapidly and effectively protects its critical capabilities from disruption caused by adverse events and conditions. RE can provide society and its critical infrastructure with means, methods and technologies to overcome unexampled events with as less harm as possible and to come out even stronger and better prepared afterwards. There are 4 R’s that are critical to the resilience engineering. Q1. There are 4 R’s that are critical to the resilience engineering. Explain them with some examples. Q2. There are 4 Strategies to increase system resilience given them in book. What strategy is most applicable to you as a software programmer and why? Q3. How do you think resilience will be different for technical systems vs sociotechnical systems? Q4. Out of three levels of security I.e. Infrastructure security, Application security and Operational security, we can only deal with application security. Although it is the area we work on, but overall security of even our application depends upon the organizational security policies. Do you agree? Comment using an example. Q5. There are 4 types of security threats namely, Interception, interruption, modification and fabrication. As a software programmer, what threat is the one you may work to avoid and how? Q6. There are 10 Design guidelines for security engineering given in the book. Which you think is the most important and should be used in your everyday software development practices.

Company A has a market value of equity of $2,000 million and 80 million shares outstanding. Company B has a market value of equity of $400 million and 25 million shares outstanding. Company A announces at the beginning of 2019 that is going to acquire Company B.

The projected pre-tax gains in operating income (in millions of $) from the merger are:

The projected pre-tax gains in operating income are expected to grow at 4% after year 2023. The company is using a discount rate of 8% to value the synergies. The marginal corporate tax rate is 35%.

Company A has decided to pay a $300 million premium for Company B. Assume that capital markets are efficient and that there is a 100% probability the deal will be closed.

If Company A were to offer 0.80 share of Company A for each share of company B, by how much the price per share of Company A would change at the time of the announcement of the acquisition?

Q.10

Women have been encouraged throughout the world to be entrepreneurs. Many reasons, some of them being to support themselves and their families; to attain the fulfillment of having started something on their own and to satisfy their desire for financial independence. Women not only create jobs for themselves and others, but also work toward growing their businesses, and constantly innovating new products and services. One such example was the partnership venture of Ms. Amna, Ms. Saeeda , Ms. Sana and Ms. Iba. This partnership firm was called as “The Beauty Salon”. Based in Qurum since inception in 2015, this SME concentrated on providing various cosmetic and beauty treatments to its clients. The company closed doors to all its clients in 2020 due to death of one of its partners, Ms. iba

You are an Independent advisor based in Muscat and is required to advise the partners of the above firm in detail about all the possible ways that this partnership could be amended. For each of the amendments, you are required to explain the procedure in detail.                               

On January 1, 2015, a machine was purchased for $94,500. The machine has an estimated salvage value of $6,300 and an estimated useful life of 5 years. The machine can operate for 105,000 hours before it needs to be replaced. The company closed its books on December 31 and operates the machine as follows: 2015, 21,000 hrs; 2016, 26,250 hrs; 2017, 15,750 hrs; 2018, 31,500 hrs; and 2019, 10,500 hrs. Compute the annual depreciation charges over the machine’s life assuming a December 31 year-end for each of the following depreciation methods. (Round answers to 0 decimal places, e.g. 45,892.)

Assume a fiscal year-end of September 30. Compute the annual depreciation charges over the asset’s life applying each of the following methods. (Round answers to 0 decimal places, e.g. 45,892.)

Part B: Based on the financial statements that were prepared with this data, complete the following financial ratio calculations and provide a narrative discussion of these results as compared to industry averages (provided.)

Ratios required:

Ratio Industry Average

1. Profit margin 3.2%

2. Return on assets (use ending assets) 6.0%

3. Return on common equity (use ending common equity) 15.6%

4. Receivable turnover (use ending receivables) 8.5 x

10. Debt to total assets (use ending assets) 37.0%

Your solution should include the required ratios for each year and then provide a narrative discussion regarding the results as they compare to the industry averages. This analysis should discuss whether or not Smith's Inc. is better or worse than the industry average but it should not stop there. You should also include a discussion as to why or how the difference can be explained, i.e., the reason for the variance. The final solution is to be provided in the Word document, with the module and part clearly identified. The narrative discussion will reference the appropriate ratio and the comparison to the appropriate industry average.

Is there a difference between community college statistics students and university statistics students in what technology they use on their homework? Of the randomly selected community college students 67 used a computer, 86 used a calculator with built in statistics functions, and 22 used a table from the textbook. Of the randomly selected university students 40 used a computer, 88 used a calculator with built in statistics functions, and 39 used a table from the textbook. Conduct the appropriate hypothesis test using an αα = 0.01 level of significance.

1. What is the correct statistical test to use?

   • There is sufficient evidence to conclude that the distribution of the technology that community college statistics students use for their homework is the same as the distribution of the technology that university statistics students use for their homework.
   • There is insufficient evidence to conclude that type of student and type of technology used for statistics homework are independent.
   • There is sufficient evidence to conclude that type of student and type of technology used for statistics homework are dependent.
   • There is insufficient evidence to conclude that the distribution of the technology that community college statistics students use for their homework is not the same as the distribution of the technology that university statistics students use for their homework.
   • There is sufficient evidence to conclude that the distribution of the technology that community college statistics students use for their homework is not the same as the distribution of the technology that university statistics students use for their homework.
