An element's radioactive decay can be determined through a single equation which requires imputing the isotope's half life, its rate of decay and the decay time since the rate of decay is measured.
Exponential growth and decay can be determined with the following equation: N = (NI)(e^kt). In this equation, "N" refers to the final population, "NI" is the starting population, "t" is the time over which the growth or decay took place and the "k" represents the growth or decay constant. If necessa
Percentage can be calculated on a basic calculator by multiplying with the percent button. If the percent button is not present, the percent amount can be converted to a decimal and that can be multiplied instead.
To calculate percentages on a calculator, divide the part by the whole and then multiply the answer by 100. For example, to find what percent of 80 is 20, divide 20 by 80. The result is 0.25, then multiply 0.25 by 100 which equals 25 percent.
Writing a beta decay equations involves denoting the emission of a beta particle as the loss of an electron. Beta decay involves a neutron decaying into a proton and an electron emission (beta particle); the atomic number increases by one, but the mass number remains the same. The lost electron does
Alpha decay happens when a radioactive particle decays into an alpha particle (helium-4 nucleus) and a new particle. The new particle has an atomic number that is two less than the original radioactive particle and an atomic mass equal to four less than the original particle.
The equation for gamma decay is Axy equals Axy plus the gamma symbol, where A is the parent particle's atomic symbol, x is the particle's total number of neutrons and protons, and y is the total number of protons. The gamma symbol indicates a emission of gamma energy.
A load factor is calculated with the following formula: Load Factor = Month's kWh Usage / (Peak Demand or KW x 730). A load factor is simply the energy load on a system compared to its maximum potential or peak load for a period of time.
Maximax is one of several methods for choosing between different options, such as what price to set for your services or changing your restaurant menu. When you do maximax, you list all the options and all possible outcomes. Then, you pick whichever option offers the biggest potential payoff. When y
The real GNP formula is found by determining the nominal Gross National Product (GNP) by adding capital gains of foreign earnings to the GDP. You will then need to adjust for inflation by dividing the nominal GNP by the Consumer Price Index (CPI) and then multiplying the total by 100. In the study o
