Suppose
140
geology students measure the mass of an ore sample. Due to human error and limitations in the reliability of the balance, not all the readings are equal. The results are found to closely approximate a normal curve, with mean
83
g and standard deviation
3
g. Use the symmetry of the normal curve and the empirical rule as needed to estimate the number of students reporting readings between
80
g and
86
g.

When a small object approaches a much more massive object, the smaller object can be tidally disrupted. The distance of the closest approach before being tidally disrupted is the Roche limit (recall lecture on rings of plan- ets). If the small object is a star and the large object is a supermassive black hole, the Roche limit is given by
rR= 2.4 * RS * (pBH/p*)^(1/3)
where RS is the Schwarzschild radius, ρ̄BH is the average density of the black hole and ρ̄∗ is the average density of the star.
a) Setting the average density of the supermassive black hole equal to its mass divided by the volume contained within the Schwarzschild radius, derive an expression for the mass of a black hole as a function of ρ̄∗ that would have rR = RS.
b) If the Sun were to fall into a supermassive black hole, what maximum mass could the black hole have if the Sun would be tidally disrupted before crossing the event horizon (or RS). Compare your answer with typical supermassive black holes in the galactic nuclei.
c) If the mass of the supermassive black hole exceeded the mass found above, what would be the implication in terms of the energy release of the infalling star? Could infalling stars effectively power AGNs in this case?

1）On a certain dry sunny day, a swimming pool's temperature would rise by 1.40°C if not for evaporation. What fraction of the water must evaporate to carry away precisely enough heat to keep the temperature constant?
2）A piece of iron block moves across a rough horizontal surface before coming to rest. The mass of the block is 3.3 kg, and its initial speed is 3.2 m/s. How much does the block's temperature increase, if it absorbs 74% of its initial kinetic energy as internal energy? The specific heat of iron is 452 J/(kg · °C).

a. What is its approximate modified duration for 100bps change in yield?
b. What is its approximate convexity for 100bps change in yield?
c. Using its approximate modified duration alone, how much (in % terms) do you expect the price of this bond to change if interest rates increase by 200bps?
d. Using its modified duration and convexity, how much (in % terms) do you expect the price of this bond to change if interest rates increase by 200bps?
e. Compare the actual expected change in the value of the bond if yields across the yield curve increased by 200bps for this issuer vs. the answer obtained in part d above.

A load of bricks of mass M = 185 kg is attached to a crane by a cable of negligible mass and length L = 3.19 m. Initially, when the cable hangs vertically downward, the bricks are a horizontal distance D = 1.39 m from the wall where the bricks are to be placed. What is the magnitude of the horizontal force that must be applied to the load of bricks (without moving the crane) so that the bricks will rest directly above the wall?

Cumberland County Senior Services is a non-profit organization
devoted to providing essential services to seniors who live in
their own homes within the Cumberland County area. Three services
are provided for seniors—home nursing, Meals on Wheels, and
housekeeping. In the home nursing program, nurses visit seniors on
a regular basis to check on their general health and to perform
tests ordered by their physicians. The Meals on Wheels program
delivers a hot meal once a day to each senior enrolled in the
program. The housekeeping service provides weekly housecleaning and
maintenance services. Data on revenue and expenses for the past
year follow:

The head administrator of
Cumberland County Senior Services, Judith Ewa, is concerned about
the organization’s finances and considers the operating income of
$6,400 last year to be razor-thin. (Last year’s results were very
similar to the results for previous years and are representative of
what would be expected in the future.) She feels that the
organization should be building its financial reserves at a more
rapid rate in order to prepare for the next inevitable recession.
After seeing the above report, Ewa asked for more information about
the financial advisability of discontinuing the
housekeeping program.
The depreciation in the housekeeping category is for a small van that is used to carry the housekeepers and their equipment from job to job. If the program were discontinued, the van would be donated to a charitable organization. Depreciation charges assume zero salvage value. None of the general administrative overhead would be avoided if the housekeeping program were dropped, but the liability insurance and the salary of the program administrator would be avoided.
Required:
1-a. Compute the change in net operating income for the company as a whole if housekeeping program be discontinued.
1-b. Should the housekeeping program be discontinued?
Yes
No
2. Would a segmented income statement format be more useful to management in assessing the long-run financial viability of the various services?
Yes
No

A 10-year-old girl was brought to an outpatient clinic because she complained of sore throat and a lump in her neck. On examination, she was observed to have a tonsillar abscess, swollen glands, and widespread bruising in the extremities. She also had a low-grade fever. She was treated with antibiotics and released, but she failed to progress over the next 2 days. Hematology laboratory tests revealed a WBC of 8.0 x 10^9/L, a hematocrit of 28%, and a platelet count of 10 x 10^12/L peripheral blood differential count revealed 3 band neutrophils, 25 segmented neutrophils, 8 lymphocytes, 1 monocyte, and 63 blasts.
The patient’s parents were contacted, and the girl was immediately admitted to the hospital. A bone marrow examination was performed and revealed an infiltration of blast cells in the marrow.
Immunophenotyping was performed on the bone marrow cells. The results show the cells have CD 11b, CD 13, CD 33, and CD15 markers.
1. Why are the hematocrit and platelet count decreased?
2. What is immunophenotyping and why is it an important test?
3. What is the most likely diagnosis based on these test results?
4. How would the results differ in the immunophenotying of the cells had CD 10, CD 19, CD 20 and CD 22 markers?

C = a + b Yd
Yd = (1 – t)Y
X = g – mY
a. Derive the equilibrium GDP (Y) and the expenditure multiplier (Me ) expressed in general notations.
b. Suppose I = $900 billion, G = $1,200 billion, a = 220, b = 0.9, t = 0.3, g = 500, and m = 0.1. Solve for the equilibrium GDP (Y) and the expenditure multiplier (Me ) using your answers to part a.
c. Is the expenditure multiplier (Me ) with variable import spending (refer the numerical solution of Me from part b) larger or smaller than the expenditure multiplier (Me ) with fixed import spending? In addition to an algebra comparison, provide an intuition with your answer. Hint: The expenditure multiplier (Me ) with fixed import spending (i.e. constant X)) is 1 1−?(1−?) , in the problem, b = 0.9, t = 0.3.

C = a + b Yd
Yd = Y – T
a. Derive the equilibrium GDP (Y), the expenditure multiplier (Me ), and the fixed tax multiplier (MT ) expressed in general notation.
b. Suppose government changes government spending G and fixed taxes T by the same amount (G = T). Derive the balanced budget multiplier, Y/G with G = T, using solutions of Me and MT from part a. [Hint] Y = meG + mTT
c. Illustrate the effect on income Y of a balanced budget increase in government spending and taxes (i.e., G=T>0) on the income expenditure (45 degree) diagram. Fully label your diagram.
