b. Compare what happens to potential energy, kinetic energy, and total energy as the skater moves up and down the track. What general statement can you make about the relationship between potential and kinetic energy?

c. Notice that the bar entitled “Thermal” energy does not deviate from zero. This represents an energy that is transformed into "heat" energy. What must be true of this skate park for this to remain at zero?

d. Vary the skater's Mass with the slider on the right while the simulation is running. Describe the similarities and differences that changing the mass has on the bar graphs.

e. Click on the Friction tab at the bottom and choose the parabola track. Place the skater at the top. Examine the bar graphs as the skater oscillates back and forth. What is happening to the energies present? Explain how you know that energy is still being conserved.

f. Run the simulation as in part “e” until the skater comes to a stop. What form did the skater’s initial energy end up as?

Use the above graphs to answer the questions below. a. Estimate roughly where was he located at the times listed below:

• zero seconds? ___________________

• 6.8 seconds? __________________

• 8.1 seconds? _________________

• 5.3 seconds? _________________

b. If his maximum height is 4 m (measured from the bottom of the track), what is his height at the times below

• zero seconds? ___________________

• 6.8 seconds? __________________

• 8.1 seconds? _________________

• 5.3 seconds? __________________

Examine the kinetic energy curve on the graph above. Given that his mass was 75kg calculate his speed at the times below using Ek = ½mv2 .

Speed at zero seconds: show any work below v0 = ______________ m/s

Speed at 6.8 seconds: show any work below v0 = ______________ m/s

Speed at 8.1 seconds: show any work below v0 = ______________ m/s

Speed at 5.3 seconds: show any work below v0 = ______________ m/s

Choose the Friction tab (bottom of screen) and select the half-pipe track. Now select on Grid. This will provide a scale for you to measure heights in meters. You may assume that the mass of the default skater is 75kg. Run the simulation and sketch the Energy vs time graphs below. You know the shapes of these from above, you simply need to determine the transition times (period of motion). Use a stopwatch to get a rough idea. Be sure to include a legend to represent your different energy curves.

LimeBike is a start-up founded in 2017 located in San Mateo, California. Its mission is to make shared bicycles accessible and affordable. The company has taken the basic idea of shared bicycles and eliminated the need to return the bike to a docking station, which may not be near the cyclist’s destination.

LimeBike charges $1 per 30 minutes of riding. Students receive a discounted rate of $0.50 per ride.

To use LimeBike, you first use the LimeBike app to locate one of the citrus-colored bikes near your location. Once you are at the bike, you scan the QR code on the bike or enter the bike’s plate number into the app to unlock the bike. When you are finished using the bike, you park the bike by a bike rack or post – anywhere that is legal and visible. Once you press down the back wheel lock, the trip is finalized and your payment is processed – all within the LimeBike app.

LimeBike operates the bicycle networks within cities, eliminating the need for cities to maintain the bikes or deal with other logistics. The shared bicycle network is not dependent on government funding, making it appealing to cities with tight budgets.

LimeBike just raised $12 million in funding from investors to expand its operations. It is set to begin operating in as-of-yet undisclosed cities in April or May of 2017.

In the following paragraphs, the first and last sentences are correct. Rewrite the middle sentences of to put the theme at the beginning and the rheme at the end of the sentences.

Paragraph 1

Atoms of all elements consist of a central nucleus surrounded by a "cloud" containing one or more electrons. We can think of these electrons as occupying a series of well-defined shells. The number of electrons in its outermost shells determines the behaviour of a particular element. Other factors, such as the total number of electron shells, also play a part in determining behaviour but it is the dominance of the outer electron configuration that underlies the periodic law and justifies the grouping of the elements into groups or families.

Paragraph 2

Every substance contains a certain amount of heat, even a relatively cold substance such as ice. The substance's molecules are in continual motion and, by this motion, possess kinetic energy which produces heat. The average kinetic energy of the molecules are measured by temperature. Cooling to the point at which molecular movement ceases completely should thus be possible. Scientists are very interested in this point, absolute zero, but it is in practice unattainable. At temperatures close to absolute zero some materials exhibit remarkable properties, such as superconductivity and superfluidity.

Paragraph 3

Nauru is so small that the plane lands in what is best described as the capital's main street. To stop cars when planes are landing the seaward side of the runway has traffic lights at each end. Well-fed and brightly clothed Naurans cowd the tiny air terminal with their smart cars. The only hotel, the luxurious Menen, is a 10-minute drive half way round the island and is where new arrivals are driven off in Japanese minibuses. The well-paved road passes rows of neat, modern houses, set among the trees.

(David Lascelles, The Financial Times)

Paragraph 4

The most striking example of value rigidity I can think of is the old south Indian Monkey Trap, which depends on value rigidity for its effectiveness. A hollowed-out coconut chained to a stake makes the trap. A monkey can put its hand though a small hole in the coconut and grab some rice inside. The monkey can put its hand into the hole but cannot take its fist out with rice in it. The monkey's value rigidity traps it when it reaches in. The rice cannot be revalued. He cannot see that freedom without rice is more valuable than capture with it.

Discussion: Is This What We Should Spend Our Money On?

No unread replies.No replies.

The Federal budget is made up of three parts for planning purposes: Mandatory spending, which is enabled by ongoing appropriations, and so does not require new spending authorization; Discretionary spending, which has to be re-authorized each year; and the Interest on the Federal debt. For our purposes, because we are not looking at the legislative process, it is one single large spending pool. Below is overall Federal spending in the USA in 2018

2018 Federal Spending.  (Links to an external site.)View the document or the Interactive Graphic.

So you can see that in 2018 Federal spending added up to $4.1 trillion, or 20% of then US GDP of $20.5 trillion. Obviously this was more than revenues, which at $3.3 trillion left a deficit of (a bit less than) 800 billion dollars, or 3.9% of GDP. We spent 24% of Federal money on Social Security + 14% on Medicare, which = 38% and growing of all US Federal expenditure on retired people. Another 15% of the entire budget in 2018 was spent on the US military. In addition we spent 9.5% on Medicaid, which is medical assistance for poor people. And we spent 15.6% on natural resources and the environment, general science, space & technology, general government, community & regional development, agriculture, administrative costs of Medicare & Social Security, energy & commerce, and housing credit programs. Another 7.9% and growing was spent on servicing the national debt. About four-fifths is spent on retired people, the poor, the military and the Federal debt.

On the Federal level, education spending is allocated to Pell grants, work-study, guarantees of student debt, and Head Start, a program for poor pre-school children. The great majority of spending on education in the US is on the state and local levels, although the Federal government plays a regulatory role.

Similarly, with respect to the environment, the Federal government plays primarily a regulatory role -- in this case, most spending in terms of mitigation is by private industry. The largest exception is the national park system; there are also state and local parks and reserves.

Do you think these are the best priorities for US Federal government spending? Do you propose some other set of priorities? If so, what? Write about three paragraphs. Please use outside academic-level sources to support your position.

you are provided with four scenarios. For each scenario, you are required to answer the following question:

What are the access-to-care issues in the given situations? Suggest at least two solutions to address the access-to-care issues in these scenarios.

Scenarios:

Mr. A is a 30-year-old African American male. His employer provides for his health insurance, which covers emergency room visits, hospitalization, and some preventive-care services such as yearly physicals. Whenever he schedules appointments for preventive-care services, he has to spend one to three hours at the doctor's office. Additionally, he has to schedule follow-up appointments for laboratory tests after each office visit.

Mrs. B is a 30-year-old African American woman with two children. She is employed at a workplace that does not provide the employees with health insurance. Mrs. B and her children make frequent visits to the emergency room for healthcare services.

Mr. C is an unemployed 52-year-old Asian male who has not seen a doctor in at least eight years. He speaks limited English. He has been experiencing some health problems. He was recently told about a free clinic located within a couple of miles of his apartment. There are no Asian healthcare providers at the local health clinic. He has some concerns about healthcare provided by anyone other than Asian healthcare providers.

Mrs. D and her husband, a middle-aged Caucasian couple, recently moved to a rural community. They are both on medications for chronic health conditions, which require them to go for bimonthly doctor visits. Their car recently broke down and there is limited bus service in their community. They are having a difficult time going for their appointments and obtaining their medications. They are also less motivated to seek care because they have some major disagreements with the primary care doctor who is a young woman in her early thirties.
