Consider a satellite of mass ms in circular orbit around Earth, a distance h above Earth's surface. Assume the Earth is a sphere with radius Re and mass Me.
(a) As the satellite travels in circular orbit, will its speed increase, decrease, or remain constant? Explain.
(b) The only force acting on the satellite is gravity, so the satellite is in freefall. Why doesn't the satellite get closer to Earth's surface?
(c) Determine the ratio of the force of gravity on the satellite while in orbit to the force of gravity on the satellite while on the surface of Earth. Simplify your answer; no complex fractions! Give your answer in terms of Re and h.
(d) Starting with Newton's second law, determine an equation for each of the following quantities. Give your answers in terms of Me, Re, h, and the universal gravitation constant G.
(i) the freefall acceleration of the satellite,
(ii) The orbital speed of the satellite,
(iii) the period of orbit, which is the time it takes the satellite to complete one orbit around Earth.
(e) Determine the work done by gravity as the satellite moves through one-half of its circular orbit.
(f) Consider a near-Earth orbiting satellite (h=0.10Re) that is inhabited by astronauts.
(i) Determine the ration of the freefall acceleration of an astronaut in this circular orbit to the freefall acceleration of an astronaut on Earth.
(ii) If that astronaut weights 150 pounds on Earth, how large is the force of gravity on her in orbit? Is she "weightless"?

Leyton and Dustin run a service station in a country town, the service station sells petrol and a number of other goods, which are displayed near the cash register and outside the office. Leyton and Dustin are partners in the business, though they have an old written agreement that states that neither will order goods or services over the value of $3,000 unless the contract contains signatures from both partners.
Leyton has been approached by a supplier of magazines who offers the business the delivery of 100 copies of a particular publication each month. Leyton convinced that the magazine is popular and will make some money, signs a contract with a promise to pay $5,000 in instalments for the delivery of the magazines.
The magazines arrive and Dustin is very upset, first because the magazine is quite unsuitable for display in the business and may result in a loss of customers if they see this publication, but he is also upset that Leyton has made an agreement without consulting him. There is an argument between the partners and Leyton takes sick leave and stays at home to recover from the stress of the argument. In the meantime, Dustin communicates with the supplier of the magazines and declares that the agreement to supply the publication is invalid due to a breach of the partnership agreement, and that the magazines will be returned and no payments will be forthcoming from the business.
Explain, with reference to partnership law:

Instructions
Use the same organization as in previous weeks' projects. Research the ethical challenges regarding employees (i.e., diversity, discrimination, sexual harassment, privacy, employee theft, bad leadership, etc.) that your chosen organization has faced over the past five to ten years and that they should prepare to face in the next five to ten years. Once you have developed a list of challenges, consider how having faced those challenges (or knowing that you will be facing them) will impact and be impacted by the social cause you've selected.
Tasks:
Propose your findings on the ethical challenges faced by your
organization in recent history and the near future. Be sure to:
Analyze ways in which each challenge was (and/or could be) appropriately handled and areas for improvement.
Evaluate the ethical/moral aspects of your organization that protected it from ethical challenges in the past and could protect it in the future.
Assess how ethical challenges and handling of ethical challenges could positively or negatively impact the charitable cause you've selected and how the selection of your social cause could positively or negatively impact the organization and its employees.
Submission Details:

CORPORATE VALUATION
Brandtly Industries invests a large sum of money in R&D; as a result, it retains and reinvests all of its earnings. In other words, Brandtly does not pay any dividends, and it has no plans to pay dividends in the near future. A major pension fund is interested in purchasing Brandtly's stock. The pension fund manager has estimated Brandtly's free cash flows for the next 4 years as follows: $2 million, $6 million, $11 million, and $15 million. After the fourth year, free cash flow is projected to grow at a constant 8%. Brandtly's WACC is 10%, the market value of its debt and preferred stock totals $58 million; and it has 17 million shares of common stock outstanding.
Write out your answers completely. For example, 13 million should be entered as 13,000,000.

Use Worksheet 9.1. Lexi Thomas, a recent college graduate, has decided to accept a job offer from a nonprofit organization. She’ll earn $44,000 a year but will receive no employee health benefits. Lexi estimates that her monthly living expenses will be about $2,000 a month, including rent, food, transportation, and clothing. She has no health problems and expects to remain in good health in the near future. Using the Internet or other resources, gather information about three health insurance policies that Lexi could purchase on her own. Include at least one HMO. Use Worksheet 9.1 to compare the policies’ features. Should Lexi buy health insurance? Why or why not?

You are hired as a consultant by the national corporate office to address consistently lower performance scores for at least the past five years at one branch office in DeLand, FL near a train station. While the performance ratings are still average to just below average in some cases, the scores are considerably lower than at all of the other branch offices across the country. In addition, productivity declines consistently during each summer. The job positions with poorer performance include indoor and outdoor jobs and occur with all of the positions at the branch position. Performance evaluations are identical for each of the jobs across the branches (for example, performance evaluation criteria for the production manager in DeLand, FL are the same criteria for the production managers at each of the other sites.) Upon, first review, you find that the items on the performance evaluations seem to be consistent with the expectations in each of the written job descriptions. It is now time to visit the DeLand site. The corporate office has allowed you to make suggestions directly to supervisors at the DeLand office, implement any training programs you deem to be helpful, and then report your findings to the corporate office, What are some of the things that you anticipate might account for the lower ratings? After an objective analysis of the job responsibilities, comparisons with job descriptions, interviews with staff, and systematic observations, your suspicions are confirmed. How will you address them and what suggestions will you make to the corporate office?
