interest rates. The RBA generally likes to keep inflation between the 2-3% mark‚ however‚ this may change as a result of international pressures. Generally‚ if inflation is seen to be increasing at a rate that is disproportionate to the health of the economy - or basically growing faster than it can sustain - then official rates may be raised to in order to reduce consumer spending and slow down the economy. Alternatively‚ if inflation is not increasing at a healthy rate‚ the official rate may be

Almost all of this growth is occurring in the developing regions‚ while most industrialised countries are growing very slowly or not at all‚ and in some countries the population size is even declining. However‚ these developed countries make up just one fifth of the world’s population and consequently have little impact on demographic trends. This results in the need for investigation into the causes of high rates of population growth. Religion plays a large part in the rate of population increase

Discussion The purpose of this experiment was to determine if splitting a bean would affect its rate of respiration. Splitting a bean does not impact its rate of respiration. This is shown in the data‚ while the average rate of respiration for Whole beans is 1.35 and the rate of respiration for 1.16‚ the standard error of the mean is .15. Because the standard error of the mean is so high‚ they overlap in both of the data sets‚ which shows that the data is very similar. This is better shown in the

Effect of osmosis rate on different surface areas‚ depending on different types of water solution An investigation showing the effect of surface area on osmosis rate‚ including some different types of water concentration. Osmosis is a type of passive (not requiring energy) transport of water molecules across partially permeable membrane‚ from an area of high water concentration into area of low water concentration. But how does surface area affect rate of osmosis? Surface area plays important

Analysis of High Turnover Rate Introduction High turnover rate of minorities and female employees has become a serious issue in the United States. Even though many ethnic races form this country‚ male Anglo-Saxons dominate the majority of the workforce. It is not uncommon for minority and female employees to leave their company after only working for a few years. Why has this behavior become a trend? In order to stop this trend‚ companies must ask themselves several questions. For example‚ what

This investigation tested the hypothesis: The rate of osmosis will increase as the temperature increases 2x2x2cm cubes of potato were weighed and then placed into 100mL of 10% NaCl solutions for 10 minutes. After 10 minutes the cubes were again weighed to determine the amount of mass that they lost/gained and thus get an indication of the rate of osmosis. The results collected showed that the rate of osmosis was highest in the 70°C solution and lowest in the 20°C solution

The purpose of this lab was to find my and my fellow classmates resting heart rate and record it. There were seven people in the class and we all participated in this study. There are four places to check heart rate and they are in your wrist‚ the inside of your elbow‚ the side of your neck‚ or the top of your foot. Everyone used the wrist or their radial artery. We used our middle and index fingers to gently feel for the radial artery in each others pulse. I then counted the pulse for 10 seconds

The Correlation between the Diffusion Rate of a Substance and its Molecular Weight ABSTRACT To test the effect of molecular weight on the rate of diffusion‚ various experiments were performed. One of which is the glass tube test wherein cotton balls of the same size were moistened in two different substances (NH4OH and HCl). These cotton balls were plugged at each side of a glass tube. After some time‚ formation of a white ring occurred. The white ring‚ in fact‚ is a product of the reaction between
