How does the quantum description of reality, which includes elements such as the superposition of states and wavefunction collapse or quantum decoherence, give rise to the reality we perceive? Another way of stating this question regards the measurement problem: What constitutes a "measurement" which apparently causes the wave function to collapse into a definite state? Unlike classical physical processes, some quantum mechanical processes (such as quantum teleportation arising from quantum entanglement) cannot be simultaneously "local", "causal", and "real", but it is not obvious which of these properties must be sacrificed, or if an attempt to describe quantum mechanical processes in these senses is a category error such that a proper understanding of quantum mechanics would render the question meaningless. Can a multiverse resolve it?

1. Faraday’s law of electromagnetic induction is a law that states that when the magnetic flux linking a circuit changes, an electromotive force is induced in the circuit proportional to the rate of change of the flux linkage.
Please click the link: https://phet.colorado.edu/sims/html/faradays-law/latest/faradays-law_en.html
And observe the fluctuation of induced current in the circuit by moving the magnet.

The twelfth paragraph states that the Chilean government’s "fiscal restraint" in the face of strong capital inflows during the 1990s left the government with "enough money...to cushion the economic downturn when foreign capital eventually turned tail in 1998." Explain.

4. Assume there are three possible future states for the economy (Boom, Stagnant, and Recession) with associated probabilities of 20%, 45%, nd 35%. For each future stae of the economy, a security pays either $40.00 or $20.00 with equal probability (i.e., a 50% chance of either payoff occuring).
a. What is the expected future cash flow for any given future state of the economy?
b. What is the expected future cash flow for the security?
c. Further assuming the future outcomes are one year into the future, what is the current price of the security assuming a 5% annual discount rate?
d. What is the conditional expected cash flow for each future state of nature? (Note: It will be the same for each state.)
e. Assuming the given any future state of nature, the $40.00 payoff is Event 1, and the $20.00payoff is event 2. What is the "conditional mean-zero idiosyncratic component" for the security based on the future payoffs in Event 1 and Event 2? (Note: It will be the same for each state.)
f. What is the CAPM beta for this security?

The following payoff table shows the profit for a decision problem with two states of nature and two decision alternatives:
| State of Nature | |||
| Decision Alternative | s1 | s2 | |
| d1 | 10 | 1 | |
| d2 | 7 | 3 | |
| (a) | Suppose P(s1)=0.2 and P(s2)=0.8. What is the best decision using the expected value approach? Round your answer in one decimal place. |
| The best decision is decision alternative (- Select your answer -d1 /d2) with an expected value of. | |
| (b) | Perform sensitivity analysis on the payoffs for decision alternative d1. Assume the probabilities are as given in part (a), and find the range of payoffs under states of nature s1 and s2 that will keep the solution found in part (a) optimal. Is the solution more sensitive to the payoff under state of nature s1 or s2? Round your answer in two decimal places. |
| The solution is more sensitive to (Select your answer -s1 / s2), as an increment of .......... for d1(s2) causes a break even between the decision alternatives, whereas it takes an increment of .......... , to provide the same effect for d1(s1). |

A small business owner visits his bank to ask for a loan. The owner states that he can repay a loan at $2,100 per month for the next three years and then $3,100 per month for the two years after that. If the bank is charging customers 6.75 percent APR, how much would it be willing to lend the business owner?

The theory of “rational addiction” states that past, present, and future consumptions of an addictive good such as cocaine are compliments to each other. Describe the idea behind this theory and what it then predicts regarding whether the demand for such a good is more elastic in the short run or the long run. Do the results of the research studies presented in class confirm these predictions? Explain.

Make scattered plot chart with X representing Florida and Y representing that state in question, plot the line and compute the R-square. Answer the questions:
I) What are the approximate slope and the R-squares on your chart? (10 points)
II) What is the approximate Y-intercept and what is its interpretation? (10 points)
III) What does each dot represent? (10 points)
IV) The highest dot on your chart has (approximately) the following Y-coordinate (10 points)
