Your boss asks you to design a commercial-industrial building with planned column loads of 2,000 kN. For each of the locations described below, list the type(s) of foundations you would consider in preliminary planning. Briefly explain your choice.

1) Urban fill extending to depths of ~5 m, followed by ~50-60 m of a soft lacustrine fat clay deposit.

2) Peat to a depth of 2 m underlain by a thick dense granular deposit, the groundwater table is near the surface.

3) A thin (<0.5 m) layer of topsoil over a thick (~10 m) marine sand deposit over competent bedrock.

4) Variable glacial deposits to a depth of ~20 m. These deposits consist of smaller layers of dense granular deposits and overconsolidated fine-grained deposits with cobbles and present at developed locations in the area. Groundwater is variable with several perched aquifers.

In 2001, President George W. Bush and Federal Reserve Chairman Alan Greenspan were both concerned about a sluggish U.S. economy. They also were concerned about the large U.S. current account deficit. To help stimulate the economy, President Bush proposed a tax cut, while the Fed had been increasing U.S. money supply. Compare the effects of these two policies in terms of their implications for the current account. If policy makers are concerned about the current account deficit, discuss whether stimulatory fiscal policy or monetary policy makes more sense in this case. Then, reconsider similar issues for 2009–10, when the economy was in a deep slump, the Fed had taken interest rates to zero, and the Obama administration was arguing for larger fiscal stimulus. Why might many believe that the Fed should keep interest rates at near zero levels in 2016 and beyond as growth remains stagnant?

Real GDP per capita tells us the average level of income (and expenditure) for a person in the economy. While countries with higher levels of GDP per capita tend to enjoy better healthcare, higher levels of life expectancy or higher average years of schooling (to mention a few), compared to countries with low levels of real GDP per capita, many still argue that this is an imperfect measure of the true level of well-being for members of an economy. Explain why you believe real GDP per capita may not be a very good measure of economic well-being, and briefly mention and elaborate on one or two alternative indexes or metrics that could be used instead (or in addition to). If you believe real GDP is, in fact, a near-perfect measure of economic well-being, support your position defending this measure of well-being explaining why it is a superior measure of compared to other metrics.

1.) A hiker, who weighs 860 N, is strolling through the woods and crosses a small horizontal bridge. The bridge is uniform, weighs 3220 N, and rests on two concrete supports, one on each end. He stops 1/4 of the way along the bridge. What is the magnitude of the force that a concrete support exerts on the bridge (a) at the near end and (b) at the far end?

2.) A jet transport has a weight of 1.09 x 106 N and is at rest on the runway. The two rear wheels are 17.0 m behind the front wheel, and the plane's center of gravity is 11.2 m behind the front wheel. Determine the normal force exerted by the ground on (a) the front wheel and on (b) each of the two rear wheels.

3.) A clay vase on a potter's wheel experiences an angular acceleration of 8.38 rad/s² due to the application of a 18.5-N m net torque. Find the total moment of inertia of the vase and potter's wheel.

Airnova Inc. has two types of bonds, Bond D and Bond F. Both have 8 percent coupons, make semiannual payments, and are priced at par value. Bond D has 2 years to maturity. Bond F has 15 years to maturity.

Airnova Inc. is considering four different types of stocks. They each have a required return of 20 percent and a dividend of $3.75 for share. Stocks, A, B, and C are expected to maintain constant growth rates in dividends for the near future of 10 percent, 0 percent, and -5 percent, respectively. Stock D is a growth stock and will increase its dividend by 30 percent for the next four years and then maintain a constant 12 percent growth rate after that.

What is the dividend yield for each of the four stocks?

What is the expected capital gains yield?

Discuss the relationship among the various returns that you find for each of the stocks.

Acme Computing Corp. has remote sites in Port Clinton and Napoleon in addition to their main site in Toledo. There are currently 29 devices connected to the network in Toledo. The corporate plan is to link the Port Clinton and Napoleon offices to Toledo via T-1 lines. The remote offices which are due to open in the next 4 weeks will have a small number (less than 14) of devices connected to a LAN in each office. The corporation has obtained Cisco routers to deploy at the remote locations and a Cisco for use in Toledo (www.cisco.com). In the near future, Acme plans to connect to the Internet and Toledo will serve as the connection point.

a) Propose a sub-network design that will meet the needs of Acme Corporation. For the first implementation of the plan, assume that we will use unnumbered connections between the routers and that the routing protocol will use static IP addresses.

b) Identify any initial issues that you can foresee.

1) A lower price for batteries would result in a(n)

A) decrease in the demand for flashlights.

B) increase in the demand for batteries.

C) Increase in the demand for flashlights.

D) Decrease in the demand for batteries.

2) If Kindle e-readers and Nook e-readers are substitutes, a lower price for Nooks would result in a(n)

A) Decrease in the demand for Kindles.

B) Increase in the demand for Nooks.

C) Increase in the demand for Kindles.

D) Decrease in the demand for Nooks

3) Which of the following demonstrates the law of supply?

A) When shirts producers expected shirt prices to rise in the near future, they decreased their current supply of shirts.

B) When salt prices rose, salt sellers decreased their quantity supplied of salt.

C) When the price of soccer balls rose, soccer balls sellers increase their quantity supplied of soccer balls.

D) When computer production technology improved, computer producers increased their supply of cars.

You want to determine the percent of sulfate in an unknown sample of a hydrated metal sulfate with the formula My(SO4)x·nH2O. You dissolve 0.2888 g of your unknown in DI water and heat to near boiling. You react the dissolved unknown with a hot barium chloride solution and you collect the barium sulfate you make via gravity filtration. The filter paper weighed 0.597 g after a piece was torn off. The dry barium sulfate crystal and the filter paper weighed 0.910 g. Answer the following:

1. What is the molar mass of barium sulfate?

2. What is the molar mass of sulfate?

3. How many moles of sulfate were produced?

4. How many grams of sulfate were produced?

5. What is the percent sulfate?

I know the answer for the first two but im unsure of the next couple of questions. Thank you in advnadce :)

During the summer of 2017, fifteen former leaders of the White House Council of Economic Advisors signed a letter to President Trump urging him not to place tariffs on imports of steel into the United States. The letter notes that “Among us are Republicans and Democrats alike, and we have disagreements on a number of policy issues. But on some policies there is near universal agreement. One such issue is the harm of imposing tariffs on steel imports.” Tariffs are taxes imposed by government on imports. Those who endorse tariffs and other barriers to free international trade believe that such barriers protect domestic industries and the jobs of their employees.

Why do many economists, including those who have served for both Republican and Democratic administrations, support free trade policies and oppose tariffs and trade barriers even if these barriers are designed to protect domestic workers from losing their jobs? What types of jobs would be most vulnerable to job losses due to competition from imports?
