What happens to the magnetic domain structure of a ferromagnet when it is placed in an external magnetic field?

- Domains whose magnetisation is at odds with the direction of the external field will vanish spontaneously at the expense of their neighbouring domains.

- Domains will re-orientate their magnetisation parallel with the external field, starting with the domain which is most add odds with the external field direction.

- Magnetic moments near Bloch walls will reorientate themselves in parallel with the external field.

- Magnetic moments near Bloch walls will reorientate themselves in line with the orientation of the adjacent domain if this means they will be closer to parallel alignment with the external field.

Explain what will happen as a result of the following events. In each case, draw an aggregate demand and short-run aggregate supply diagram showing the initial equilibrium output level (Y0) and price level (P0). Show any changes and indicate the final equilibrium output level and price level.

A. The economy is operating near full capacity. Now environmental pollu¬tion standards are tightened substan¬tially.

B. The economy is operating near full capacity. An import tax (tariff) is imposed on foreign consumer goods, and the central bank tries to maintain the interest rate.

Farmers would like to know the amount of sunshine in given locations they may buy land.  They hypothesize that a place near the coast may have different cloud cover than a place further from the coast at the same latitude so that the sun angles are the same.   In the data sheet you have daily noontime reports of the fraction of cloud cover near the coast and inland.  Justify your acceptance or rejection of the hypothesis using these numbers, and state the confidence level you would use.

Cld cover coast: ,71,26,100,16,100,83,61,32,84,15

Cld cover inland: ,60,9,6,29,12,19,21,62,82,0,4,84,51,4,19

Which of these are actual evidence for the existence of a black hole in the center of the Milky Way, and which are not?

Stars are observed to disappear into the black hole

Bright quasar emission is detected from the center of the galaxy

Telescopes have been used to take high resolution images of the black hole's event horizon

Astronomers observe an extremely bright and compact radio source

The closest approach of stellar orbits near the center of the galaxy indicate the object is smaller than the solar system

Stellar velocities near the center of the galaxy indicate 4 million times the mass of the sun inside their orbit

HomeSuites is a chain of all-suite, extended-stay hotel properties. The chain has 20 properties with an average of 150 rooms in each property. In year 1, the occupancy rate (the number of rooms filled divided by the number of rooms available) was 70 percent, based on a 365-day year. The average room rate was $215 for a night. The basic unit of operation is the “night,” which is one room occupied for one night.

The operating income for year 1 is as follows:

In year 1, the average fixed labor cost was $416,000 per property. The remaining labor cost was variable with respect to the number of nights. Food and beverage cost and miscellaneous cost are all variable with respect to the number of nights. Utilities and depreciation are fixed for each property. The remaining costs (management, marketing, and other costs) are fixed for the firm.

At the beginning of year 2, HomeSuites will open six new properties with no change in the average number of rooms per property. The occupancy rate is expected to remain at 70 percent. Management has made the following additional assumptions for year 2:

The average room rate will increase by 8 percent.

Food and beverage revenues per night are expected to decline by 15 percent with no change in the cost.

The labor cost (both the fixed per property and variable portion) is not expected to change.

The miscellaneous cost for the room is expected to increase by 20 percent, with no change in the miscellaneous revenues per room.

Utilities and depreciation costs (per property) are forecast to remain unchanged.

Management costs will increase by 6 percent, and marketing costs will increase by 8 percent.

Other costs are not expected to change.

The managers of HomeSuites are considering different pricing strategies for year 2. Under the first strategy (“High Price”), they will work to maintain an average price of $285 per night. They realize that this will reduce demand and estimate that the occupancy rate will fall to 60.0 percent with this strategy. Under the alternative strategy (“High Occupancy”), they will work to increase the occupancy rate by lowering the average price. They estimate that with an average nightly rate of $194, they can achieve an occupancy rate of 80 percent. The current estimated profit is $75,358,035.

Required:

a. Prepare a budgeted income statement for year 2 if the “High Price” strategy is adopted. (Round your per unit average cost calculations to 2 decimal places.)

b. Prepare a budgeted income statement for year 2 if the “High Occupancy” strategy is adopted. (Round your per unit average cost calculations to 2 decimal places.)

c. Which is the correct pricing strategy for year 2.

Other costs are not expected to change.

The managers of HomeSuites are considering different pricing strategies for year 2. Under the first strategy (“High Price”), they will work to maintain an average price of $232 per night. They realize that this will reduce demand and estimate that the occupancy rate will fall to 50.0 percent with this strategy. Under the alternative strategy (“High Occupancy”), they will work to increase the occupancy rate by lowering the average price. They estimate that with an average nightly rate of $192, they can achieve an occupancy rate of 70 percent. The current estimated profit is $21,069,150.
