G10 science By Freya Li Practical Investigation Resistance in Wire Aim: To investigate if the length of wire affects its resistance and find out how the resistance changes when the length of wire increases. Hypothesis: My prediction is that as the length of wire increases‚ the resistance will also increase. This is because current is the flow of electrons in a circuit and voltage makes the electrons flow through the circuit. The electrons have to collide with the atoms in the wire‚ which makes

Colander (2010)‚ economics is the study of how human beings manage their wants and desires. Buyers based their wants and needs on marginal costs and marginal benefits. Sellers based their supply production on the consumer demand shift‚ and seller set their prices according to the demand change. That is just some of the basics of economics. There are two types of economic structure: macroeconomics and microeconomics. Colander (2010) defines microeconomics as “the study of how individual choice is influenced

How would income elasticity of demand help explain these things ? Q ( Demand ) QS0 Superior QI1 QI0 Inferior QS1 Y1 Y0 Y ( Income ) During the decline in economy activity‚ the spending power will decrease which is similar as the decline in income. Home food which is economical are inferior goods while restaurant food which is much more costly are superior goods. Therefore from the income elasticity of demand curve‚ the demand for home food will

concept of price elasticity to identify a brand’s competitors? How would that work? Firms today are in their perspective industries to maximize consumer satisfaction‚ increase revenue‚ and shareholders profits. These tasks require attention to detail when pricing their products. There are always competitors lurking and waiting by the wayside to gain market share and a competitive advantage. When identifying brands competitors‚ price elasticity is a major determinant. Demand for a product or

Practical Uses of Paralanguage & Non-verbal Communication. A year ago‚ I had an argument with my father for an hour. On a fine day after the air was cleared‚ my mother insightfully cross-analysed the argument for my better understanding of the situation. She told me the argument was aggravated NOT because of the context of the arguments but the way I put it forth. To which my reply was‚ “I was not arguing‚ that’s the way I talk.” Paralanguage Now‚ this incident brings me to the topic of paralanguage
