Price elasticity of demand Marija managed to explain perfectly what is the price elasticity and what are the factors that affect it: availability of substitutes and time. In overall‚ it is a very scholastic presentation since Marija gives in detail how the demand of goods is changing according to the availability of substitutes‚ the fluctuation of the price of goods‚ and what impact they have on the consumers if all the other factors are being stable. Though‚ there is a point of which I would add

Mechanical energy Mechanical energy is the energy that is possessed by an object due to its motion or due to its position. Mechanical energy can be either kinetic energy (energy of motion) or potential energy (stored energy of position). Introduction: We use a system consisting of two weights hanging at each end of a thin thread lying over a wheel. A photo gate is placed so that the light is interrupted by the spokes of the wheel. The data are recorded electronically and this makes it possible

Assessment Task 4 When I was on practical I observed many classroom procedures and strategies that teachers use on a daily basis. These are what I believe are the most important in constructing a positive learning environment. One critical teacher strategy that I find most important is to lay down concrete guidelines and rules within the classroom. It is important for students to know how to behave and talk to the teacher and other students in the class. The school rules were displayed

Sound is a vibration that spreads across a medium (i.e.‚ air or water) as a mechanical longitudinal wave formed by pressure. A Mechanical longitudinal wave can also be called compression wave as it generates compressions and rarefaction when traveling through a medium. (Sound Is a Pressure Wave - Physics Classroom) The amplitude of a sound wave is the difference between the pressure of the undisturbed air and the maximum pressure caused by the wave. The Speed of sound deviates with the temperature

their children who get higher grade being compared to lower grades students who don’t get all straight A during high school and college years. So‚ parents and teachers should not place unrealistic expectation on high school students to achieve a high GPA‚ which contributes to stress disorder‚ health problems‚ and a propensity to cheat on assignment. First‚ stress can be a problem that affects everyone; especially students have issues in school‚ meaning they have to get high grades to be an

Assignment On Engineering Materials (Glass) Introduction Glass is a non-crystalline solid material. Glasses are typically brittle‚ and often optically transparent. The most prevalent type of glass‚ used for centuries in windows and drinking vessels‚ is soda-lime glass‚ made of about 75% silica (SiO2) plus Na2O‚ CaO‚ and several minor additives. Often‚ the term glass is used in a restricted sense to refer to this specific use. [pic] [pic]Roman Cage Cup from the 4th century A.D. In

Part II: Modelling Overbooking Karl believes that profit maximization can be achieved if the actual number of shown up customers equals the hotel capacity. He proposes that the formula which returns the number of customers who actually show up is given by the product of booking level times the average percentage of showing up costumers. That number should equal hotel capacity. Therefore‚ the
