You may be familiar with Newton's Second Law of Motion, SF = mā. In English, this equation says: The sum, or net, (S) of the forces (F) acting upon an object equals (=) the mass (m) of the object multiplied by the object's acceleration (ā). Even if you are familiar with this famous equation, did you notice the arrows above F and a before?...

2) What were some of the key challenges they encountered? How did they overcome them? 3) What were some of the key takeaways they learned to use in the future? When I assumed the leadership of Heinz’s Asia/Pacific business, in 1993, the company’s revenues from that part of the world were hardly a blip—and I’d never visited most of the countries in the region. I made my first trip there soon after I took the job, and it really opened...

SECTION A (50) Read the case study below and answer the questions. SHORT RUN STABILIZATION AND LONG RUN COMPETITIVENESS: THE LAVITAN CASE Growth of a young country Latvia – a small, young country on the east coast of the Baltic Sea – has recently earned the title of a ‘‘tiger’’. After gaining its independence from the Soviet Union in 1991, the country embarked upon a challenging road of transitioning from a planned to a market economy. The first decade proved...

Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...
