relative population of atoms in two energy levals E1 and E2 is 10-20 calculate the enery level difference in eV. assume T=300K.
To calculate the immigration rate, divide the number of immigrants arriving in a country by the total population of that country, then multiply by 100 to express it as a percentage. This will give you the rate at which immigrants are entering the country relative to the total population.
Relative humidity is measured using a psychrometer, which consists of two thermometers: a dry bulb and a wet bulb. The dry bulb thermometer measures the air temperature, while the wet bulb thermometer has a moistened wick that cools as water evaporates. The difference in temperature readings between the two thermometers indicates the amount of moisture in the air. This difference can then be used with a psychrometric chart or formula to calculate the relative humidity.

To measure relative humidity, you would need a hygrometer, which can be a mechanical or electronic device. In addition, you may need a source of temperature data as relative humidity is temperature-dependent. Optionally, you might use a psychrometer, which consists of two thermometers – a dry-bulb and a wet-bulb – to calculate relative humidity based on the temperature difference.
Relative humidity can be measured using a hygrometer, which is an instrument specifically designed for this purpose. There are various types of hygrometers, including analog and digital models, as well as more specialized devices like psychrometers, which measure the difference between wet and dry bulb temperatures to calculate humidity. Some modern weather stations and smartphones also have built-in sensors to measure relative humidity.
There is no difference between the two. Relative risk is the same as relative ratio. Commonly abbreviated as RR, relative risk/ratio is measure of absolute risk in one population as a proportion of absolute risk in another. It is a measure of the strength of association.
To calculate the immigration rate, divide the number of immigrants arriving in a country by the total population of that country, then multiply by 100 to express it as a percentage. This will give you the rate at which immigrants are entering the country relative to the total population.
i need to know the exact formula used to calculate the relative grading thanks
Relative population size is the size of an area's population as it compares to similar areas' populations. For example, the relative population size of a country would be what rank it had compared to the population of other countries.
To calculate the relative density of a substance, you divide the density of the substance by the density of water. The formula is: Relative Density Density of Substance / Density of Water. The relative density is a measure of how dense a substance is compared to water.
Frequency distribution refers to a set of frequencies with a particular set of values into which a statistical population is grouped. Relative frequency refers to data presented in a table that demonstrates the relative frequency of multiple non-overlapping classes.

If two trains are passing each other the relative speed can be found by adding the individual speeds of the two trains. This applies if the trains are passing each other in opposite directions. Should one be passing the other and both be moving in the same direction, the difference of the individual speeds would be the relative speed of the trains.
To calculate the relative atomic mass of an element, you multiply the mass of each isotope of the element by its natural abundance, then add these values together.
