4.1 Suppose that interest rates in Australia rise relative to those in other countries.
(a) How will this policy affect real GDP in the short run if Australia is a closed economy? (b) How will this policy affect real GDP in the short run if Australia is an open economy? (c) How will your answer to part b change if interest rates also rise in the countries that are the major trading partners of Australia?

A 100 F capacitor and a 225 resistor are connected in series with a 75.0 V battery. The switch is closed and the capacitor begins to charge.
a)When does the capacitor hold 15.0 % of its maximum charge? Express your answer in milliseconds.
b)What is the voltage across the resistor at this same time?
Please state your answers as clear as possible and show all the steps and formulas used. Thank you!!!

In the Musculoskeletal System subsection of the Surgery section in your CPT book, it discusses the following types of treatment: closed treatment, open treatment, and percutaneous skeletal fixation. What do each of these terms means? What are the differences between each of these types of treatment? Choose one of the types of treatment and give an example of a procedure that would be performed using that method, along with the code that would be assigned for the example.

Let n be a positive integer. Let S(n) = n sigma j=1 ((1/3j − 2) − (1/3j + 1)). a) Compute the value of S(1), S(2), S(3), and S(4). b) Make a conjecture that gives a closed form (i.e., not a summation) formula for the value of S(n). c) Use induction to prove your conjecture is correct.

A 105‑turn circular coil of radius 2.41 cm and negligible resistance is immersed in a uniform magnetic field that is perpendicular to the plane of the coil. The coil is connected to a 14.7 Ω resistor to create a closed circuit. During a time interval of 0.167 s, the magnetic field strength decreases uniformly from 0.481 T to zero. Find the energy, in millijoules, that is dissipated in the resistor during this time interval.

Consider the following family of sets: For any n∈N, we define Q_n={ q \in Q | q= \frac{m} {n^k} for some k, m \in Z}
(That is, Q_n is the set of rational numbers expressed with the denominator that is a power of n.)
a) Is this set closed under addition, subtraction, multiplication, and division?
b) Decide the truth value of the following statement: Q 12 ⊆ Q 18 . Justify.

Cheryl Wilson, president of Rivers Company, considers $48,000 to be a minimum cash balance for operating purposes. As can be seen from the following statements, only $43,000 in cash was available at the end of 2011. Because the company reported a large net income for the year, and also issued bonds and sold some long-term investments, the sharp decline in cash is puzzling to Ms. Feldman.

Assume the that over the past couple of years your investment into a stock that pays no dividends was as follows:
| Year | Starting price | Shares bought/sold |
|---|---|---|
| 2010 | 49.8 | 50 bought |
| 2011 | 55.7 | 100 bought |
| 2012 | 50.7 | 150 sold |
What is your dollar-weighted annual return for over this period for this investment?
Enter answer in percents, to two decimal places.
Bonus exploratory question: how does this compare to the average annual return, or the geometric average annual return?
