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. From these results it was concluded that

between exchange rates‚ interest rates • In this lecture we will learn how exchange rates accommodate equilibrium in financial markets. For this purpose we examine the relationship between interest rates and exchange rates. Interest rates are the return to holding interest-bearing financial assets. In the previous lecture we have pointed out that as being a financial asset exchange rates tend to adjust more quickly to new information that goods prices. Like exchange rates‚ interest rates are also the prices

Labor rate variance is the difference between the actual labor rate and the applied overhead rate (standard rate multiplied by the number of actual hours worked). Consider this and respond to the following: • "Our workers are all under labor contracts. Therefore‚ our labor rate variance is bound to be zero." Do you agree or disagree that the labor rate variance will be zero if all workers are under labor contracts? Explain giving reasons. The concept of labor rate variance and its application

The unemployment rate An unemployed person is one who is able and willing to work yet is unable to find a job. The unemployment rate is the number of unemployed workers divided by the total civilian labor force‚ which includes both the unemployed and those with jobs. Measuring the number of unemployed workers actually seeking work is very difficult‚ but there exists several different methods to do so. Each method has its own biases and the different systems that make comparing unemployment

RATE OF REACTIONS. The reaction rate (rate of reaction) or speed of reaction for a reactant or product in a particular reaction is intuitively defined as how fast or slow a reaction takes place. For example‚ the oxidative rusting of iron under the atmosphere is a slow reaction that can take many years‚ but the combustion of cellulose in a fire is a reaction that takes place in fractions of a second (right). Chemical kinetics is the part of physical chemistry that studies reaction rates. The concepts

The discount rate Main article: Discount rate The rate used to discount future cash flows to their present values is a key variable of this process. A firm’s weighted average cost of capital (after tax) is often used‚ but many people believe that it is appropriate to use higher discount rates to adjust for risk or other factors. A variable discount rate with higher rates applied to cash flows occurring further along the time span might be used to reflect the yield curve premium for long-term

CHAPTER 4 (MANKIW) INFLATION RATES AND INTEREST RATES: THE FISHER EQUATION NOTES by: Chadia Mathurin Economists differentiate between real and nominal interest rates where: real interest: is defined as the increase or decrease in a consumer’s purchasing power experienced as a result of changes in the interest rate. nominal interest: is defined as the interest payed by the bank. Let: i denote the nominal interest rate r the real interest rate pi ‚ the inflation rate The equation for the

Free exchange Savers’ lament The complex effects of low interest rates on consumption and investment Dec 1st 2012 | from The Economist print edition WHEN interest rates hit double digits in the late 1970s‚ house-builders sent planks of wood to the Federal Reserve in protest. With rates stuck near zero‚ the protests now come from the opposite direction. The retired complain of a “war on savings”. The Fed cut rates to current levels at the end of 2008 and has promised to keep them there until
