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.

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.
A population distribution map shows how people are spread across a geographical area, indicating where they are concentrated or sparse. On the other hand, a population density map portrays the number of people living in a specific area relative to the size of that area, providing information on the level of crowding or spacing in different regions.
A psychrometer is a type of hygrometer used to measure the relative humidity in the air. It consists of two thermometers, one of which is covered with a wet cloth, allowing for the comparison of wet-bulb and dry-bulb temperatures to calculate 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.
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.
i need to know the exact formula used to calculate the relative grading thanks
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.

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.
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.
