In his double-slit experiment with electrons, jonsson used electrons with kinetic energy 50 kev.

A) Find the electron's de Broglie wavelength

B) The two slits were separated by 2.0 um. On a screen 0.350m from the slits, what was the distance between bright diffraction fringes?

C++

Define a base class called Person. The class should have two data members
to hold the first name and last name of a person, both of type string. The
Person class will have a default constructor to initialize both data members
to empty strings, a constructor to accept two string parameters and use them
to initialize the first and last name, and a copy constructor. Also include
appropriate accessor and mutator member functions. Overload the operators ==
and != such that two objects of class Person are considered equal if and only
if both first and last names are equal. Also overload operators >>, <<, and =.
Define a class called Doctor derived from the Person class. The class
should have a data member to hold the doctor's hourly rate (of type double), a
default constructor to initialize the rate to 0, and a constructor that takes
a double and a reference to an object of type Person and initializes the data
members to their appropriate values. Also include an accessor and mutator
member functions for the doctor's hourly rate. In Doctor class, redefine the
operator = such that it not only copies the first and last name, but also
copies the hourly rate.
Define another class called Patient derived from the Person class. This
class should have a data member to hold the patient's primary physician (of
class Doctor). Include a default constructor that would call the default
constructors of class Doctor and Person to initialize the object; also include
a constructor that accepts a reference to an object of class Doctor and Person
and initializes the Patient object's data members to their respective values.
Add accessor and mutator member functions to access or set the primary
physician.
Finally, define a class called Billing that would hold information about
medical bills. This class should have the following data members: an object of
type Doctor to hold the doctor to whom the money is paid, an object of type
Patient to hold the patient who pays the money, and a variable of type double
to hold the amount due. The Billing class will have a default constructor that
initializes amount due to 0.0 and calls the default constructors for Patient
and Doctor objects and a constructor that accepts references to Doctor and
Patient objects and the amount of hours (type int). The latter constructor
will calculate the amount due in the following fashion:

* if the doctor involved in the bill is the patient's primary physician,
then the amount due is hours multiplied by the doctor's hourly rate;

* if the doctor involved is not the patient's primary physician, then
the amount due is hours times doctor's hourly rate times 1.25.

Write a main function that would prompt the user to enter the patient's
name, their primary physician's name and rate, another doctor's name and rate,
and the amount of hours spent in the doctor's office. Then the program will
calculate and output the amount patient owes for doctor's services.

Note: two doctors are considered the same if and only if their names match
(i.e. you can assume no doctors with the same name and different rates exist).

Lab 1: Using the Scientific Method Worksheet

At a local town meeting, one of your neighbors complains that a nearby residence is killing his flowers because of the chemicals he uses to wash his cars. He claims that the soap runs into a stream that flows very close to his flower beds. As an inquiring student of science, you wonder whether soap can truly affect flower growth.

Based on the observation given to you, use the following questions to explain how you would set up your experiment and analyze your results.

1.       State your hypothesis. Remember that a hypothesis must be specific and testable. For example, stating that detergents are bad is not a good hypothesis (“Bad” is a generic term, it would be better to use a metric that is measurable).

2.       Explain how you would set up your control and treatment groups. What would be the same between the groups and what would be different? What species would you use for each group and how many plants total would you use?

3.       How would you collect your data for your experiment? What tools and units of measurement would you use? How often would you collect data and would you use the same methodology for both your treatment and control groups? Be specific in your answers.

In every experiment, there are some unintentional differences between the control and treatment groups. These are called sources of error. If these sources of error can be corrected we call them avoidable sources of error. An example of an avoidable source of error may be the amount of water provided to the plant. We can avoid this error by watering the plants in each group, the same amount at the same time of the day.

4. List some possible sources of avoidable and unavoidable error in your fertilizer experiment that were provided to you as examples.

5..       Explain the difference between a theory and a hypothesis.

6.       Explain the difference between the ‘everyday’ use of the word theory and the definition of a scientific theory.

7.       Why is it important to educate people on the true definition of “theory”?

ACCOUNTING STARBUCKS 10-K (2016-2018)

Review the 2016-2018 10-Ks, Part 1, Items 1, 1A, 2, 3, and Part II, Items 7 and 8. Part I contains a discussion on the business model, risk factors, properties, and legal issues. Part II contains Management’s Discussion and Analyses, the financial statements and the notes to the financial statements. All these statements are referred to as management assertions. Parts I and II contain discussions on many types of risk that the business may be exposed to. You should read through all these areas. Once your team has read through Parts I and II, you are to answer a set of questions at the end of this section of deliverable two. The following narrative elaborates on each area you are to read.

Part 1, Item 1. Business

In this discussion, Starbucks discusses its business model, how it segments it financial information, and how it categorizes and earns revenue.

Part 1, Item 1A. Risk Factors

In this discussion, Starbucks discusses the risks that it has identified as material and has decided to share with the public. Although a company such as Starbucks has to disclose risks, the SEC madates a separate section to discuss risks. However, risks can be identified by reading other areas of the Annual Report and observations of its store operations.

Starbucks identifies the following 15 material risks:

1. Economic conditions in the U.S. and international markets could adversely affect our business and financial results.

2. Our success depends substantially on the value of our brands and failure to preserve their value, either through our actions or those of our business partners, could have a negative impact on our financial results.

3. Incidents involving food or beverage-borne illnesses, tampering, adulteration, contamination or mislabeling, whether or not accurate, as well as adverse public or medical opinions about the health effects of consuming our products, could harm our business.

4. The unauthorized access, use, theft or destruction of customer or employee personal, financial or other data or of Starbucks proprietary or confidential information that is stored in our information systems or by third parties on our behalf could impact our reputation and brand and expose us to potential liability and loss of revenues.

5. We rely heavily on information technology in our operations and growth initiatives, and any material failure, inadequacy, interruption or security failure of that technology could harm our ability to effectively operate and grow our business and could adversely affect our financial results.

6. We may not be successful in implementing important strategic initiatives or effectively managing growth, which may have an adverse impact on our business and financial results.

7. We face intense competition in each of our channels and markets, which could lead to reduced profitability.

8. We are highly dependent on the financial performance of our Americas operating segment.

9. We are increasingly dependent on the success of certain international markets in order to achieve our growth targets.

10. Increases in the cost of high-quality arabica coffee beans or other commodities or decreases in the availability of high-quality arabica coffee beans or other commodities could have an adverse impact on our business and financial results.

11. Our financial condition and results of operations are sensitive to, and may be adversely affected by, a number of factors, many of which are largely outside our control.

12. Interruption of our supply chain could affect our ability to produce or deliver our products and could negatively impact our business and profitability.

13. Failure to meet market expectations for our financial performance and fluctuations in the stock market as a whole will likely adversely affect the market price and volatility of our stock.

14. The loss of key personnel or difficulties recruiting and retaining qualified personnel could adversely impact our business and financial results.

15. Failure to comply with applicable laws and changing legal and regulatory requirements could harm our business and financial results.

Part 1, Item 2. Properties

In this discussion, Starbucks discloses select properties that it owns, providing locations, sizes and purposes. This information can help a reader understand what properties may be at risk and how Starbuck’s operations could be affected if something were to happen to one or more properties.

Part 1, Item 2. Legal Proceedings

Starbucks elaborates on their legal proceedings in Item 15, Commitments and Contingencies. Many companies do the same.

Part II, Item 7. Management’s Discussion and Analyses

This discussion is management’s interpretation of the results of its operations. An important point to be made is that this is management’s interpretations, not anyone elses. Management of companies tend to highlight the positive and suppress the negative. They tend to guide the discussion they way they want. In this section, you may get a better idea what risks management may find important and those they may try to minimize. For your purposes, it is filled with good information that may help you further understand the trends in the horizontal, vertical, and ratio analysis that you performed.

Part II, Item 8. Index to the Notes to the Consolidated Financial Statements

In this discussion, management further clarifies information contained in the income statement, balance sheet and statement of cash flows. Starbucks discloses eighteen notes. However, for purposes of this project we are only going to focus on notes 1, 5, 7, 8, 9, and 15. In Note 1, Summary of Significant Accounting Policies, only focus on the discussion about the business, estimates, cash and cash equivalents, Receivables, net of Allowance for Doubtful Accounts, Property, Plant and Equipment, and Revenue Recognition. Note 5 discusses inventories in detail and will give you insight on where Starbucks get inventory and how it categorizes it. Note 7 contains Supplemental Balance Sheet Information, which discusses Property, Plant and Equipment, and Accrued Liabilities. Note 9 discusses Debt (Liabilities). In this section, Starbucks discusses in a lot of detail how it funds its operations. This discussion is involved. You may want to read it just to see how complex accounting for debt can be and the risks that Starbucks takes to pay back financing agreements. Item 15 discusses Commitments and Contingencies. What is important in this section is the legal proceedings, which is a gold mine for identifying potential risks.

Then, after you read those sections you have to answer the following 5 questions, as a Q&A, not an essay, about a paragraph for each question:

1) Of the 15 risks that Starbuck’s management discloses, which one do you think could most adversely affect the balance sheet and why?

2. Of the 15 risks that Starbuck’s management discloses, which one do you think could most adversely affect the income statement and why?

3. Of the 15 risks that Starbuck’s management discloses, which one do you think could most adversely affect the Cash Flow Statement and why?

4. Risk number 10 above states “Increases in the cost of high-quality arabica coffee beans or other commodities or decreases in the availability of high-quality arabica coffee beans or other commodities could have an adverse impact on our business and financial results.” Which ratios would be adversely affected if increases in cost or supply chain disruptions occurred for arabica beans? Explain why.

5. Compare your readings of management’s assertions and your findings of your vertical, horizontal, ratio and chart analysis. Discrepancies may exist between what the ratios are indicating and what management is telling you. Is management telling the public one thing, but the financial information indicates another? Explain to the best of your ability.

THANK YOU SO MUCH!

To meet rising demands for health care, a new form of clinics has begun to emerge: clinics run by nurse practitioners says the New York Times.

• About 250 health clinics across America are now completely run by nurse practitioners.
• These nurses require a master's degree that includes two or three years of advanced training in treating and diagnosing diseases.
• A new proposal endorsed by the American Association of Colleges of Nursing for 2015 would require nurse practitioners to have a doctorate of nursing practice.

Many of these nurse practitioners are limited in what they can and can't do based on state law. In some states, nurse practitioners are completely free to treat patients and give prescriptions. However, some states won't allow these clinics without at least one trained physician.

These clinics staffed with nurse practitioners offer an avenue for alleviating some of the strain being put on primary care physicians. Indeed, the Affordable Care Act will bring 32 million uninsured people into the health system and there aren't enough primary care physicians to cover them. Furthermore, physicians are poorly distributed, many of them opting to work in urban areas rather than rural towns.

Some critics of having nurse practitioners run clinics argue that the quality of care is compromised for patients.

• However, data has shown nurse practitioners provide good quality care.
• One-hundred and eighteen published studies over 18 years found that nurse practitioner-led clinics were at the least equivalent, if not better, when compared to doctor-led clinics.

Moreover, nurse-led clinics are cheaper than traditional doctor-led practices. Furthermore, these clinics are small and don't need a variety of practitioners to keep the clinic at full capacity. Finally, nurse practitioner-led clinics provide patients with an alternative to the emergency room, which results in large savings.

Question:

Discuss your position and analyze how this problem could become a major problem and affect more Americans in the future.
