1. In the demonstration where a magnet is brought near a loop, what determines the induced current?
| the strength of the magnetic field intercepted by the loop |
| the rate at which the number of magnetic field lines intercepted by the loop changes |
| the spacing of the magnetic field lines intercepted by the loop |
|
the number of magnetic field lines intercepted by the loop |
2.
Which describes the flux of a magnetic field that is tangent to a section on a closed surface?
| The flux is zero. |
| The flux is negative. |
| The flux is positive. |
3. Which is true about the emf induced in a loop by a magnet?
| It is equal to the inverse of the magnetic flux through the loop. |
| It is equal to the inverse of the rate at which the magnetic flux through the loop changes. |
| It is equal to the rate at which the magnetic flux through the loop changes. |
| It is equal to the magnetic flux through the loop. |
4. When the magnetic flux through a loop increases, which is true about the induced current?
| It produces a magnetic field in the direction opposite the existing magnetic field. |
| It produces a magnetic field but the direction depends on the rate at which the existing field changes. |

Nursing Facilities and Home Health Care are the chosen facilities
· Describe the roles and responsibilities of the administration in the nursing facilities and home health care
· Identify and list the sources of financing available to consumers for the various programs provided by your chosen facilities. Identify the key public and private sources of reimbursement available. Also discuss the role played by managed care and its impact on long-term care reimbursement.
· Describe the various
government and private resources available that assist in
developing and maintaining quality improvement programs in your
chosen facilities. Describe the ways in which quality and cost are
controlled in your chosen facilities. Also discuss the ethical
aspect of access to care in the facilities, including
rationing.
Based on your observations and learning from the two facilities,
discuss the changes brought in the long-term care system to make it
reach full status as a competition-driven system. You may include
the following points in your discussion:
· Discuss the changes made in the control mechanisms (external and internal) in order to control the management, financing, and quality in the long-term care systems.
· Discuss the changes taking place in long-term care reimbursement system in order to provide better reimbursement options both to consumers and providers.
· Discuss the changes made in the efforts of providers to accommodate changing magnitude of the day-to-day needs of long-term care consumers.

Kaelea, Inc., has no debt outstanding and a total market value of
$90,000. Earnings before interest and taxes, EBIT, are projected to
be $8,000 if economic conditions are normal. If there is strong
expansion in the economy, then EBIT will be 20 percent higher. If
there is a recession, then EBIT will be 30 percent lower. The
company is considering a $34,000 debt issue with an interest rate
of 6 percent. The proceeds will be used to repurchase shares of
stock. There are currently 3,600 shares outstanding. Assume the
company has a market-to-book ratio of 1.0.
a. Calculate return on equity, ROE, under each of
the three economic scenarios before any debt is issued, assuming no
taxes.
b. Calculate the percentage changes in ROE when the economy expands or enters a recession, assuming no taxes.
Assume the firm goes through with the proposed recapitalization
and no taxes.
c. Calculate return on equity, ROE, under each of
the three economic scenarios after the recapitalization.
d. Calculate the percentage changes in ROE for economic expansion and recession.
Assume the firm has a tax rate of 35 percent.
e. Calculate return on equity, ROE, under each of
the three economic scenarios before any debt is issued. Also,
calculate the percentage changes in ROE for economic expansion and
recession.
f. Calculate return on equity, ROE, under each of the three economic scenarios after the recapitalization. Also, calculate the percentage changes in ROE for economic expansion and recession, assuming the firm goes through with the proposed recapitalization.

5.3 BEP Example
Bill Braddock is considering opening a Fast ‘n Clean Car Service Center. He estimates that the following costs will be incurred during his first year of operations: Rent $9,200, Depreciation on equipment $7,000, Wages $16,400, Motor oil $2.00 per quart. He estimates that each oil change will require 5 quarts of oil. Oil filters will cost $3.00 each. He must also pay The Fast ‘n Clean Corporation a franchise fee of $1.10 per oil change, since he will operate the business as a franchise. In addition, utility costs are expected to behave in relation to the number of oil changes as follows:
Number of Oil Changes Utility Costs
4,000 $ 6,000
6,000 $ 7,300
9,000 $ 9,600
12,000 $12,600
14,000 $15,000
Bill Braddock anticipates that he can provide the oil change service with a filter at $25 each.
Instructions
(a) Using the high-low method, determine variable costs per unit and total fixed costs.
(b) Determine the break-even point in number of oil changes and sales dollars.
(c) Without regard to your answers in parts (a) and (b), determine the oil changes required to earn net income of $20,000, assuming fixed costs are $32,000 and the contribution margin per unit is $8.

Your company plans to sell 2000 ounces of silver next week decides to use silver futures contracts to create a minimum variance hedge. Each futures contract has 125 ounces of silver attached. The spot and futures prices for silver the day your company opened its position were $16/ounce and $20/ounce, respectively. The table below shows both spot and futures price changes over a three day period.

Problem 19-4A Mary Willis is the advertising manager for Bargain Shoe Store. She is currently working on a major promotional campaign. Her ideas include the installation of a new lighting system and increased display space that will add $57,600 in fixed costs to the $396,000 currently spent. In addition, Mary is proposing that a 5% price decrease ($60 to $57) will produce a 20% increase in sales volume (20,000 to 24,000). Variable costs will remain at $36 per pair of shoes. Management is impressed with Mary’s ideas but concerned about the effects that these changes will have on the break-even point and the margin of safety. Compute the current break-even point in units, and compare it to the break-even point in units if Mary’s ideas are used. (Round answers to 0 decimal places, e.g. 1,225.)

Athena, a 60-year-old woman, has noticed that her 85-year-old mother, Dorothy, is becoming increasingly isolated and unhappy. Dorothy does not want to spend time with her friends and every time Athena visits, Dorothy seems to want to cut the visit short. Athena knows that Dorothy has experienced changes in her vision over the last 10 years. Dorothy complains to Athena that her peripheral vision seems limited and she is unable see very well in the dark. Her doctor tells her that she is developing macular degeneration, which will further affect her vision. Also, she is having a hard time hearing what people are saying, especially at social gatherings or a restaurant. Athena understands that the senses change with age and she believes that many of the changes experienced by her mother are common for her age. But Athena is concerned about her mother’s psychological state. She doesn’t really understand why her social behavior and emotional well-being have changed. Describe how sensory related changes that occur with aging can lead to changes in quality of life, including social behavior and emotional well-being, as has happened with Dorothy. Be sure to describe the impact of both hearing loss and loss of vision.
Bullet point with brief explanation is fine. Describe in relation to late adulthood

Ortelere, a retired teacher, has built up a substantial amount of funds in her retirement plan before she retired because of "involutional psychosis" (a form of mental illness).
She has previously specified that a lowered monthly retirement benefit would be paid to her so that her husband would get some benefit from the retirement plan if she died before he did. After her mental problems began, she changed her payout plan and borrowed from the pension fund (....ok, lady, you're getting the money based on 'your' decision! We have relied on 'your' decision 'today'. Positions are changing, parties will be 'affected' based on 'representations'.)
As a consequence of the changes she made, her husband lost his rights to benefit. Two months after she made the changes, she died. The husband sued to reverse the changes his wife made, claiming she was not of sound mind when she made them.
