Economics IB past paper questions Structural questions 1. (a) “The price elasticity of demand and the price elasticity of supply for many primary commodities tend to be low.” Explain what is meant by this statement‚ and how this contributes to the problem of price instability for primary commodity producers. [10 marks] (b) Evaluate the view that it is best to allow primary commodity prices to be determined purely through the free interaction of market forces. [15 marks] 2. Explain what

IB CASE STUDY * CHAPTER 2 [OBJ 2] Successful companies have insightful strategies‚ great supply chains and sharp financial systems. Ultimately‚ though‚ success is a function of the people who start and sustain the company. The challenge of putting the right person into the right job in the right place at the right time for the right compensation takes us to the front lines of international business. One can evaluate HRM from many perspectives. Two reasons motivate an executive perspective

| 2012 | | Toby Rheinberger Lab Partner: Jeremy Saba | [The Effect of surface area to volume ratio and solute concentration on osmosis.] | The aim of this experiment was to test the effect of surface area on osmosis and the effect of solute concentration on osmosis. To test this aim to hypotheses were devised. 1) If potato pieces are immersed in various salt solutions‚ then the pieces with the greatest surface area to volume ratio will experience the greatest weight change‚ because more

IB Physics Internal Assessment Andy Tang Research Question In this internal assessment‚ I am given a cantilever to find the physical properties of it. I decide to investigate the relationship between the force I act on one side of the cantilever and the maximum acceleration the tail can reach. This experiment will be also showing the elasticity of the cantilever. Since I pull down one side of it and fixed the other side‚ when I cut the string‚ it will bounce up and down until all the internal

Network Design: Logical and Physical Design In networking terminology‚ the term network topology refers to the entire structure of the network. There are two primary parts to the topology definition: the physical design‚ which is the actual layout of the wire (media)‚ and the logical design‚ which defines how the media is accessed by the hosts. The physical designs that are commonly used in networks are the Bus‚ Ring‚ Star‚ Extended Star‚ Hierarchical‚ and Mesh. A bus topology uses a single
