1.         The closed end of a Boyle’s law crooks tube is shown to the right. The internal diameter of the tube is 4.0 mm. The tube is cylindrical topped by a hemisphere with the same radius as the tube. It is 3.8 cm from the mercury to the bottom of the hemisphere.

What is the volume of gas trapped in this tube in cm³?

2.         4.25 L of air was trapped in a balloon at sea level where the pressure is 1.00 atm. You throw it in your car and drive to red Lodge Montana (at 5500 ft) and then up the Beartooth Pass at 10,006 ft, (See the next page) where atmospheric pressure is 0.703 atm.

            What is the volume of the balloon on top of the pass?

3.         In actuality it is cold on top of this pass. The winter snow typically keeps the pass closed until about Memorial Day and sometimes July 4^th.

            Suppose the balloon was filled on a hot day when T = 28^oC. On top of the pass on a June day is it a cool 3^oC. (I hope you remembered you coat!)

            Considering both the pressure and temperature, what is he balloon’s volume?

Consider the FCC and HCP closed packed structures in units of ro, the radius of the close-packed atom. Explain why there are no common HCP based ionic structures with all of the octahedral sites filled or all the tetrahedral sites filled. Use Pauling’s rules and your knowledge of the ABAB and ABCABC stacking sequence to answer the question.

A physician orders mannitol (Osmitrol) for a client with a closed head injury. Which of the following should the nurse recognize as the desired response to this medication?

a). The blood pressure increases to 150/99 mmHg

b). Urinary output increases to 175 cc/hr

c). There is decrease in the level of activity

d). There is absense of fine tremors of the fingers

8. When an customer account is closed due to nonpayment, the account to be debited is:

a. Cash                                     c. Allowance for Uncollectible Accounts

b. Accounts Receivable              d. Uncollectible Accounts Expense

9. Johnson Co. uses the Aging Method to estimate uncollectible Accounts. An aging schedule shows that $60,000 in accounts are estimated to be uncollectible. The Allowance for Uncollectible Accounts already has a $5,000 credit balance. For what amount should the account be adjusted (credited)?

a. $65,000                    c. $60,000

b. $70,000                    d. $55,000

10. Jacobs Co. uses the Percentage of Credit Sales Method to estimate uncollectible accounts.  Past experience indicates that about 2% of credit sales will become uncollectible. Credit sales for the current month are $400,000.  The Allowance for Uncollectible Accounts already has a $3,000 credit balance.  For what amount should the account be adjusted (credited)?

a. $83,000                    c. $8,000

b. $5,000                      d. $11,000

In a closed economy with no foreign trade, spending on consumer goods (C) is related to national income (Y) according to the table below : -

Assuming that the government is spending £30 billion per year on the infrastructure and firms are investing £30 billion

(a) What is the equilibrium level of national income (Y)?               

(b) Calculate the marginal propensity to consume domestic goods and services.                                                                                         

(c) Calculate the value of the multiplier in this case.                        

(d) Using a diagram to help your answer, explain what would happen if government spending rose by £20 billion.                                          

Suppose a closed economy (economy that does not engage in international trade) is described by the following table.

a. What problem will occur in the economy in Year 2 if no policy is pursued?

b. Describe the fiscal policy tools that could be used to combat the problem. Carefully explain all steps in the link between policy and outcomes. What impact will this policy have on the various components of the aggregate expenditures? What will happen to the real GDP and Price level as a result of these policies?

c. Describe the monetary policy tools that could be used to combat the problem. Carefully explain all steps in the link between policy and outcomes. What impact will this policy have on the various components of the aggregate expenditures? What will happen to the real GDP and Price level as a result of these policies?

d. Will your answers to (b) and (c) change if this was an open economy. In what way?

A 0.75 L bottle is cleaned, dried, and closed in a room where the air is 20°C and 44% relative humidity (that is, the water vapor in the air is 0.44 of the equilibrium vapor pressure at 20°C). The bottle is brought outside and stored at 0.0°C.

a. What mass of water condenses inside the bottle?

b. Would water condense at 10*C?

. Assume a simple closed Keynesian model where the MPC is 0.9 and the MPIM is 0.1. Also assume that potential real GDP is $2000 million, while actual (equilibrium) real GDP is $1200 million.

            a. What is the GDP gap?

            b. Is there an inflationary or recessionary gap?

            c. What change in government spending is required to restore the economy to full

                employment GDP? Show graphically using a Keynesian cross diagram.

d. What change in lump-sum taxes would bring about the same result?

e. Now assume that a Balanced Budget Amendment is passed, so that increases in

     government spending must be accompanied by equal increases in lump-sum

     taxes. What change in both G and T will close the GDP gap? (HINT: What is

     the balanced budget multiplier in this model?)

Compare the effect on GDP of an adverse demand shock in the closed and open economy cases using graphs based on the open economy IS-MP model. Assume flexible rate.
