Microeconomics Chapter 4 Essay - 1220 Words
Chapter 4 2. Why do economists use percentages rather than absolute amounts in measuring the responsiveness of consumers to changes in price? Why do economists use percentages rather than absolute amounts in measuring the responsiveness of consumers to changes in price? Economists use percentages rather than absolute amounts for two different reasons. The first reason for using percentages rather than absolute amounts has to do with the affect a particular amount can have on demand. The example in our book refers to using dollars or pennies, in one instance the dollar amount leads to a demand that is elastic, however that same dollar amount in pennies would lead one to see that demand is inelastic. The amount is the same,â⬠¦show more contentâ⬠¦So, for Ed=1 this represents unit elasticity. 8. The owner of a health club asks you for advice about whether the company should raise or lower the price of its membership this year based on the following information: last year the club raised the price of its membership by 5% and the number of members paying the same fee fell by 7%. Based on the information provided we could use the price elasticity formula to determine if the price change represented elastic or inelastic demand. Divide the change in quantity by the change in price (0.07/0.05) and find the price elasticity coefficient. Using what we have learned about price elasticity, it is clear that Ed=1.4, which is elastic. Using the table given in example 4.2, we see that a prince increase on an elastic good results in total revenue decrease. The owner should lower prices to see a total revenue increase. 11. A gasoline station very near a professional football stadium parks cars on its lot to make money on game days. Last year it charged $4.00 per car and parked 1000 cars.

Taking a Look at the Cold War - 786 Words
The Cold War The Cold War was a time after World War II, so from 1945 to 1991, where the USA (United States of America) and the USSR (Union of Soviet Socialist Republics) had very different views on what the new world should be like. The Cold War drew international interest for decades. Many major conflicts occurred. The conflicts consisted of the Vietnam War, the Korean War and many others. For most people though, the Cold War was about the creation and the use of weapons of mass destruction, this was the most troubling issue. The Cold War was mainly a disagreement between two very different government systems. Basically it came down to capitalism versus communism. Each of these systems of government were held highly by each respective country. Both sides were fighting to spread their cause, taking every chance they could to expand anywhere in the world. During the Cold War, the USSR in 1945 included all the different countries that now exist individually around Russia. After World War II they were all part of a huge country, until the Soviet Union collapsed 1991. War can be classified into three different types. Hot War, this is actual warfare, where communication has failed and the militaries are fighting. The next type of war is the Warm War, this is where communication is still going on and a chance for a peaceful outcome is still present, but the Army, Navy and other military are all ready for the call to fight.

Introduction To Instrumentation And Measurements
Question: Explain what a measurement system is with the aid of a block diagram. You need to explain the main system elements and the process of the system. The primary sensor: Signal Conditioning: Data transmission : Display or Presentation: An example of how a measuring system works : Compare the following types of transmission systems and give examples of their usage: (a) Coaxial cable (b) Twisted-pair cable (c) Flat cable (d) Fibre-optic Answer: The measuring system: A system which is designed to specify anything which can be measured is called a measuring system. It involves the selection of unit of measurements comparing the quantity with the standard unit. The standard chosen should be of the same of nature as the quantity to be measured. Examples of measuring systems: Temperature: reservoir temperature, Building temperature. Measurement System: resistance thermocouple is used to measure the reservoir temperature and QAA made sensor is used to measure the building temperature. Pressure: High pressure, vacuum Measurement system: for vacuum measurement ionization gauge is used and high pressure is measured using gauges. Measuring System Elements Primary sensing elements: Primary sensing element is the first element which makes first contact in measurement system. Then, the signal is converted into electrical signal but it is limited to theoretical purpose only. Transducers are the elements which converts physical signals into electrical signals. Variable conversing element: The signal output from the primary sensing element may be of any kind. It may be electrical or any mechanical signal. Sometimes there is an error in output signal and we are not able to get output. For any instrument it is very important to convert the output signal in specified or desired results. Variable manipulation elements: It is just a change of numerical value to the electrical signals. Its main function is to makes the duplicate signal and preserving the original signals. Voltage amplifier is the perfect example of variable manipulation elements. Signal conditional element: Signals received from transducer have some information which is further verified in the system. There can be some signal distortions which are then purified with the help of amplifiers. In the amplification process, the amplitude of the signal is increased with the help of levers, gears, and electronic, pneumatic, and hydraulic amplifiers. This increase in the amplitude is named as gain. Data transmission elements: The signal element carried from the signal conditioning elements produces an output later with the help of transmission elements. If we take the examples of air traffic controls air planes are separated by the control system but they are connected by data transmission elements. Data presentation elements: It is the last stage of presenting the data transmission. At this step all the signal wave forms are presented on virtual display on TV screen or LED monitor. CRT and oscilloscope are also the examples of display. Here is the block diagram of measuring elements : Functional elements of pressure gauge: If we take the example of pressure gauge there is bourdon tube, which is very good example of measurement system. In this, air is entered through bourdon tube then air reaches through a link. Here, with the help of air link is jerked which affects the sector pinion. The Pressure will be indicated on the gauge with the help of these gears moves. Functional elements of thermometer: Thermometer is another example of measuring system. In thermometer, mercury act sas a primary sensing element. When mercury comes in contact with heat it expands and due to this reason mercury rises up we get the desired reading. Co axial cable: It consists of centre conductor surrounded by dielectric core. The braided shield surrounds the core and jacket protects the shield. This type of cable is generally used for communication purpose. It can be also used for the transmission purpose of data. Sometimes telephones companies also used these types of cables. It is called so just because of it carries the signal surrounded by another concentric channel. Twisted pair cables: The most common wire in the data communication is the twisted pair cable. It is a medium transmission cable consisting of two insulated wire arranged in regular spiral pattern. These cables can also be used for telephonic communication. It can supports to 10 TO 1000 Mbps. It can be used in Ethernet networks. It helps to lower the cable susceptibility most modern Ethernet networks. Flat cables: Flat cables are also known as ribbon cable. It is most widely used in computer data transmission. It consists of plastic base film with metallic wire inside. NASA also used these cables in space mission so that it would be easy for the data transmission made contact with astronauts. Fibre cable: Flat cables are long thin strands of very pure glass. They are arranged in bundles called optical cables used to transmit the light signals. There are 3 parts: Core: the centre of fibre where the light travels. Cladding: outer optical material surrounding the core. Buffer coating: plastic coating that protects the fibre from damage. Optical fibre cable Comparission Of Transmission Systems FACTORS COAXIAL CABLES TWISTED CABLES FLAT CABLES FIBRE CABLES Capacity It can transfer data 10 to 1000 Mbps It is having wide bandwidth In this quantity of band width is low It is having ling bandwidth. Uses It can be used for internet connection For telephonic purpose Can be used for TV transmission It can be used for high band width Shapes size Copper wire with metal jacket In single circuit two conductors Two conductor cable Fibre made of glass Advantage High data transfer Very thin cable Smaller than co-axial cable Only for long distance communications Disadvantage Signal leakage problem is there Electromagnetic interference It must be kept away from metal objects Complex structure of wire References: Introduction to instrumentation and measurements, Northrop Robert B Second edition.
