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

experiment is to determine the rate law and the activation energy for the reaction between persulfate ion‚ S2O82-‚ and iodide ion‚ I-: S2O82-(aq) + 2 I-(aq) 2 SO42-(aq) + I2(aq) The rate law can be written as Reaction rate = (1) Where m and n are the orders with respect to S2O82- and I-‚ respectively‚ and k is the rate constant. Determining the rate law involves determining the values of m and n. The temperature dependence of the rate constant is given by (2)

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

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

the solution that a potato cube is placed in. The temperatures that were tested in this investigation were 0°C‚ 20°C (room temperature)‚ and 70°C. 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 national unemployment rate fell to 4.4 percent in October the lowest level of unemployment since May 2001. This is a sign of unexpected strength in the job market. [The unemployment rate is based on a survey of households‚ rather than the survey of employers used to calculate the payroll number. Unemployment does not include full-time students‚ the retired‚ children‚ or those not actively looking for a paying job.] The unemployment level is defined as the labor force minus the number of people

The society as a whole is worse off. This is because cash is the financial asset and it becomes is a liability of the government upon the time you found the cash. So‚ the taxpayers will have to make up for the government liability. 2. The average rate of return on investment in large stocks has outpaced that on investments in T-Bills by about 8% since 1926 in US. Why‚ then‚ does anyone invest in T-Bills? Answer: This is because T-bill is regarded as an almost risk free asset as it is backed

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
