When the flat open side of a charged coil was brought near the flat open side of the coil connected to a galvanometer (both coils parallel to each other), the galvanometer deflects very little. How do you know they need to be parallel and why is this the case? Where is north and south if the coil is acting like a bar magnet?

Why is the core CPI better suited for understanding inflationary pressures than the headline CPI? List and briefly describe three theoretical causes of inflation in the short run. If GDP is currently running faster than potential GDP, can we say, based on that observation alone, that inflation will rise in the near future? Why or why not?

The big advantage to owning a home is that eventually (hopefully around retirement), you will no longer have a monthly payment for housing (although you will always have taxes and upkeep.) That said, home ownership is not always the good move.
Do you own, or hope to own in the near future? If not, what are your reasons for preferring to rent/lease?

Compared virus sequences with human and avian. they are over 95%similiar.
Based on your results (which of course are limited—it would be necessary to do many more comparisons in reality), do you think there is evidence that human adaptation is occurring in H5N1 viruses that might merit concern about human-to-human transmission in the near future?

An Indonesian foreign firm agreed to sell and deliver goods to a Malaysian company that paid a considerable sum of money in advance. However, the contract was frustrated because of the 5.0 magnitude of an earthquake near Bima in West Nusa Tenggara. The Malaysian company claimed the right to recover the deposit they paid prior to the frustrating event. Advise the Malaysian company.

A company is planning a plant expansion. They can build a large or small plant. The payoffs for the plant depend on the level of consumer demand for the company's products. For the large plant, the company expects $90 million in revenue if demand is high and $40 million if demand is low. For the small plant, the company expects $55 million in revenue if demand is high and $20 million if demand is low. The cost of the large plant is $5 million. The small plant cost is $1 million.
The company believes that there is a 72% chance that demand for their products will be high and a 28% chance that it will be low.
Construct a payoff and regret matrix based on the given information.
What is the decision according to the EMV criterion? Be sure to support your answer.
Is your decision sensitive to the demand assumptions given for this problem? You may answer generally, such as “very sensitive” or “not very sensitive” as long as you support your answer.
The company can pay a market research firm to survey consumer attitudes towards the company's products. The market research firm cost is $100,000. The market research firm has provided the following cross tabulation showing recent results.

Lazer Technologies Inc. (LTI) has produced a total of 20 high-power laser systems that could be used to destroy any approaching enemy missiles or aircraft. The 20 units have been produced, funded in part as private research within the research and development arm of LTI, but the bulk of the funding came from a contract with the U.S. Department of Defense (DoD).
Testing of the laser units has shown that they are effective defense weapons, and through redesign to add portability and easier field maintenance, the units could be truck-mounted.
DoD has asked LTI to submit a bid for 100 units.
The 20 units that LTI has built so far cost the following
amounts and are listed in the order in which they were produced:
