ready-made gifts in the market cannot satisfy the customers’ needs anymore. So‚ our company has designed a brand new promotional gift. It can best suit our clients’ needs and lifestyles. This is – a heart rate watch. First of all‚ if you look at this paper‚ you can see that this watch has a function that has never been designed for before – a heart rate monitor. It enables the users to measure their heart rate while doing exercises. Actually‚ the underlying purpose of this design is to immerse

The incarceration rates of Norway‚ Australia‚ and Singapore can are much lower compared to the United States. In Norway the murder rate is less than half of that in Australia and robbery rate is significantly lower as well. The rates of all of the three first world countries i researched were surprising to me. I think they are surprising to me because Singapore have a very very low crime rate‚ and i would believe that is because they have very strict rules there compared to other places such as Australia

Official Cash Rate The Official Cash Rate (OCR) is the interest rate set by the Reserve Bank of Australia to meet the inflation target specified in the Policy Targets Agreement. The current agreement defines price stability as annual increases in the Consumers Price Index (CPI) of between 2 and 3 per cent on average over the medium term. A media release is issued at 2.30 pm after each Reserve Bank Board meeting‚ with the Board’s decision taking effect the following day. Changes to the official

Introduction The purpose of this experiment was to determine the rate law graphically from the rate of disappearance and the x y values also the specific rate constant (k). Activation energy was also determined‚ and the effect of catalyst was evaluated in the reaction between peroxodisulphate ion S2O82-‚ and iodide ion‚ I-. S2O82-(aq) + 3 I-(aq) --> 2 SO42-(aq) + I3(aq) The general expression for the rate law‚ given this overall reaction‚ is: rate of disappearance of S2O82- = k[S2O82-]m[I-]n Chemical

AMDG THE RATE OF PHOTOSYNTHESIS The Factor of Carbon Dioxide I. Introduction In this lab‚ the rate of photosynthesis will be measured by manipulating a variable that is needed for the process of photosynthesis. Photosynthesis is the process by which plants use light energy‚ carbon dioxide‚ and water to produce oxygen and glucose. This release of products provides the necessary nutrients for all forms of life. In water‚ leaves‚ usually float in water due to the gases such as carbon dioxide and

Fama and French (FF) model and the efficiency of the Capital Asset Pricing Model (CAPM). The comparison of the Fama and French Model and CAPM (Sharpe‚ 1964 & Lintner‚ 1965) uses real time data of stock market to practise its efficacy. The implication of the function in realistic conditions would justify the utility of the CAPM theory. The theory suggests that the expected return demanded by investors on a risky asset depends on the risk-free rate of interest‚ the expected return on the market portfolio

Changing the Rate of Reaction PART 1: PARTICLE SIZE Question: How does changing the particle size of marble (CaCO3) affect the rate of reaction when it is added to hydrochloric acid (HCl)? Hypothesis: If I change the particle size of marble to test how to change the rate of a chemical reaction‚ than the chemical reaction with the smallest marble particles will produce CO2 the quickest because the larger the surface area‚ the more place the hydrochloric acid will have to collide with the marble

The rate at which the reaction occurred for the 100% concentration is 1.45 mg/dL per minute. For the 50%‚ the rate was 3.05 mg/dL per minute‚ and for the 25%‚ the rate was 2.76 mg/dL per minute. As seen‚ the rate fluctuated from the lowest rate at 100% and the greatest rate occurring at 50%. As mentioned earlier‚ the Collision Theory states the rate of a chemical reaction is proportional to the

exercise affect your breathing and heart rate?” and my hypothesis was “If you exercise then your heart and breathing rates will go up because your body needs more oxygen to be circulated so that your body can keep up.”. My hypothesis was correct‚ as proven by my test. My partner‚ Brian’s heart rate when it was resting was 56 beats per second and his breathing rate was 40 beats per second. We made him do jumping jacks for ten seconds and his heart and breathing rates both went up. His heart rate increased

Examine the main trends in the birth and death rates in the UK since 1900 As the population of a country increases‚ there will be certain factors affecting the people of that country; the birth rate‚ and the death rate are two of the major demographic trends. Since 1900 the UK has changed greatly‚ as has the demography of the country. The Birth rate - the number of live births per 1000 of the population per year originally was fairly high due to the fact that child labour was legal in Victorian
