(3) The US produces about 12 million barrels of oil per day and consumes about 22 million barrels per day (mbpd). Global production and consumption are about 100 mbpd. About 0.75 mpbd come from federal land, and about 1.75 mbpd come from federal waters (primarily the Gulf of Mexico). The current oil price is about $50, the elasticity of oil supply is 0.1 and the elasticity of oil demand is -0.2.

a. Using these numbers, calculate the long-term effect on prices and quantities of banning drilling on federal land.

b. Using these numbers, calculate the long-term effect on prices and quantities of banning drilling on federal land and federal waters.

Suppose the economy is experiencing a recessionary gap of $0.5 trillion. The marginal propensity to consumer is MPC = 0.2. To mitigate or close the gap, the fiscal government need to choose between two options: increase government spending G or decrease taxes. Fill in the gaps with numerical answers unless otherwise instructed. Round your answers to one decimal place (for example, 1.25 ~ 1.3).

1. The value of the spending multiplier is at most equal to .
2. The value of the tax multiplier is at most equal to .
3. Suppose the government chooses to not change the taxes. Then, it should increase spending by at least $ trillion in order to close the gap.
4. Suppose the government chooses to not change government spending. Then, it should decrease taxes by at least $ trillion in order to close the gap.

1. For what kinetic energy is the de Broglie wavelength of an electron equal to its Compton wavelength? Express your answer in units of mc2 in doing the calculation, and then use mc2 = 0.5 MeV.(Answer: 0.2 MeV)

2. A beam of electrons with energy 1.0 eV approaches a potential barrier with U = 2.0 eV, whose width is 0.10 nm (see a figure below). Estimate the fraction of electrons that tunnel through the barrier. (Hint: use the relation of probability and the wave function, and the expression for wave function for barrier penetration)

3. Calculate the Fermi energy of sodium (n= 2.65·10^28 m^-3). This metal has a single valence electron per atom.(Answer: 3.25 eV.)

Pulp containing paraffin wax is to be dewaxed in a continuous countercurrent extraction system using kerosene. The pulp containing the wax is kerosene-free when entering the extractor, and contains 20% paraffin wax and 80% pulp. After extraction, it must not contain over 0.2 lb wax / 100 lb wax-free pulp. The kerosene used for the extraction contains 0.05 lb of wax per 100 lb kerosene. Experiments show that the pulp retains 2.0 lb of kerosene per lb of kerosene- and wax-free pulp as it is transferred from cell to cell. The extract from the extraction battery is to contain 5 lb wax per 100 lb of kerosene. How many stages are required?

A refrigerator is running with tetrafluoroethane (R1-34a) as the fluid and working based on the following cycle.

Saturated vapor at -12^oC is entering the compressor and leaving it at 40^oC. The superheated vapor after the compressor then condensed at constant pressure to saturated liquid, which ethers the “Joule-Thompson” throttling valve and back to the initial pressure. Assume your system is operating ideally, with a cooling load of 0.2 kW (200 J/s).

(a) Draw the cycle on the P-H diagram and showing each of the steps.

(b) Develop the energy balance for each step, and calculate heat and mechanical power per kg of fluid for each step.

(c)What is the flow rate of cooling fluid needed?

(d) What is the coefficient of performance (COP) of the refrigerator?

For this question ask for the expected return -beta relationship .

Must I repeat the E(R) formula for Beta F1 & F2 and then compare the answers?

pg. 139 of Investments 11th edition thanks!

There's the question:

4. Suppose the there are two independent economic factors F1 and F2. The risk free rate is 6% and all the stocks have independent firm specific components with a standard deviation of 45%. Portfolios A and B are both well diversified with the properties:

Portfolio

A 1.5 (Beta F1) 2.0 (Beta F2) 31% (Expected Return)

B 2.2 (Beta F1)  -0.2 (Beta F2) 27% (Expected Return)

What is the expected return beta-relationship in this economy?

thanks again.

A producer of a variety of salty snacks would like to estimate the average weight of a bag of BBQ potato chips produced during the filling process at one of its plants. Determine the sample size needed to construct a 99​% confidence interval with a margin of error equal to 0.007 ounces. Assume the standard deviation for the potato chip filling process is 0.05 ounces.

1. Given a vector, a, of length n, write down the MATLAB expressions that will correctly compute the following:

a.        ln (3 + a + a² )

A couple was at a ski lodge and went to happy hour from 5pm to 9pm. The bar stops serving at 10pm. They leave the ski resort on a snowy night and are driving back to the hotel which is about an hour’s drive from the resort. At 12 am a passerby sees a car off the road in the trees. He finds the male unconscious and injured behind the wheel. The female is deceased. The passerby calls 911 and it takes an hour for them to come. The male arrives at the hospital at 2 am and his blood is drawn at 2:30 am. The male is found to have a BAC of 100mg/dl in plasma.

Male weighs 70 kg

Calculate if he is going to jail or not and why?

How many drinks did he consume?

Minimum # of drinks to achieve BAC?

Clue: the key thing to realize is the happy hour ended at 9 pm and the bar closed at 10 pm. therefore, what assumptions can be made about whether he was absorptive or post-absorptive?
