1.Description "In many ways, the Federal Reserve does not control the level of interest rates nor the money supply. Rather, this is controlled by the actions of individual banks throughout the economy." Explain the rationale behind this statement. What action is required by the banks for Federal Reserve policy to be effective in stimulating the economy? What can the banks do to negate a Fed stimulus?

2.In 2014, short-term interest rates were near zero, and yet the economy was still sluggish with low rates of economic growth and relatively high unemployment. What monetary policies should be pursued in such an environment? How might they work?

150 words, per question please.

Explain the following observations, using diagrams to illustrate your answer wherever possible:

(a) Steel nails used to hold copper roofing sheet in position failed rapidly by wet corrosion.

(b) The corrosion of an underground steel pipeline was greatly reduced when the pipeline was connected to a buried bar of magnesium alloy.

(c) Mild-steel radiators in a central heating system were found to have undergone little corrosion after several years' service.
(d) A reaction vessel for a chemical plant was fabricated by welding together stainless steel plates containing 18% chromium, 8% nickel and 0.1% carbon. During service, it was observed that the vessel corroded badly near the welds.

Ch.11 Derivatives

State whether you agree or disagree with the following statement. Explain why.

“You. expect. volatility. of a stock’s. returns .to .double. in the. near future. but you. are not sure if the stock. will go. up or down .in value. The. market. consensus. is that the volatility. will remain. the same. If you want. to speculate. on your expectation., you should consider buying. (as opposed to selling) both call and put options on this stock (as opposed to only calls or only puts) before the anticipated increase in volatility.”

(Note: You are only considering call and put positions on this stock. You are not considering other ways to profit from your expectation, such as buying or short selling the stock itself.)

Glycine and proline are both non-polar amino acids, and both are very likely to be found at the surface of proteins. What physical characteristic of each is responsible for this observation?

1) Both glycine and proline are small.
2) Glycine is small, and proline is rigid.
3) The side chains of both these amino acids make favorable interactions with molecules near the surface of proteins.
4) Both amino acids make strong interactions with each other and therefore are likely to be found next to each other in a protein.

The EU Central Bank is worried that with Brexit and decreasing GDP growth rates in Germany it will have to take action in 2018. Given that the Central Bank’s risk (i.e. discount) rate is near zero what actions will be taken?

a. Explain the actions you expect the Central Bank to take and explain in macroeconomic measurement, modeling and movement terms what the Central Bank’s actions will have on EU exchange rates and exports with the U.S.

b. Use macro models and macro movement sequences to explain what actions youexpect the FED to take in response to the actions of the EU Central Bank and what movements in U.S. GDP and inflation rates will occur by the end of 2018.

Q.7 MRI machine uses magnetic field to create detailed images of human soft organs. Can you
elaborate the basic concept of working of MRI scanner? How the strong magnetic field is
produced in MRI scanner to scan the organs? Discuss the role of radio waves in MRI machines?
Write down major parts used in MRI machine. What would happen if the north-pole end of a bar
magnet is held near a positively charged piece of plastic? Justify your answer. X-ray machine
and MRI machine do the same job of human organ scanning. Analyze both the machines and
discuss three merits and demerits of it.

(Include full solutions)You and your friend Paul want to have a bet on how fast it can take to reach another friend Peter who is near the star Sirius B. Knowing that the star has a proper length of 8.6 light years from Earth, Paul thinks that since the maximum speed of your ship is 70% that of the speed of light, it will take about 9 years to get there. However, you reason that around 12 years will make more sense.

a)      Who is right from the perspective of you and Paul?

b)      When you reach Peter and explain the bet, he disagrees about who was right, why is that?

When considering buildings, it is important to identify the natural frequencies of beams. The implication will be that rotating equipment (e.g. pumps, compressors, washing machines, etc.) are selected so that the natural frequency of the beam is not excited thus brining the entire structure into resonance and causing damage.

A beam will have an infinite number of natural frequencies. The natural frequencies of a beam are the roots of a characteristic equation (which can be obtained using various analytical methods). Consider a beam whose characteristic equation is given by:

cos(0.1012x)cosh(0.1012x)=1

where x is the natural frequency in Hz.

Problem :

Use the Newton-Raphson method to find the natural frequency of the beam near 46 Hz.
