Arithmetic density refers to the total number of people per unit area of land, calculated by dividing the population by the total land area. In contrast, physiological density measures the number of people per unit area of arable land, focusing on the population supported by land suitable for agriculture. This distinction highlights how arithmetic density can be misleading in assessing population pressure on resources, while physiological density provides insight into the sustainability of agricultural practices in relation to population.
Look up the density of steel. It should be no different in a spaceship than on Earth.
Calculators are no different than computers. The tiny chip use binary to come up with the anwer.
If they are all numbers - no letters other than e or pi, then they are arithmetic. Otherwise they are probably algebraic. But beware, phi is also arithmetic.
Mass is the amount of substance an object can have
Individual atoms may be heavier or lighter. Also, the spacing between atoms may vary.
Arithmetic density is a population measurement that calculates the total number of people per unit of land area, while physiological density measures the number of people per unit of arable land. In essence, arithmetic density provides a broad measure of population distribution, whereas physiological density specifically focuses on population pressures on agricultural resources.
Not necessarily. Physiologic population density takes into account only habitable land, while arithmetic density considers total land area. So, in countries with large uninhabitable areas, physiologic density may be higher than arithmetic density.
False.
Physiologic density is the number of people per unit of arable land. In the case of Pakistan, the physiologic density is likely less than the arithmetic population density due to large areas of arid or non-arable land. This means that while Pakistan may have a high total population, much of it may be concentrated in areas with better access to arable land.
Physiologic density is always greater than arithmetic density. It is based on the amount of arable land (which is always likely less than the total area), which makes the density greater because it uses a smaller area.
Different oils have different densities; usually a bit less than the density of water.
Arithmetic Density has limitations on providing a way to understand the pressure the population exerts on the land, by making larger countries who have large amounts of population seem more spread out than it really is.
Look up the density of steel. It should be no different in a spaceship than on Earth.
Number theory explains why arithmetic works.
Because ice is a frozen solid and water is not.
There are different densities of oils used in cars. It's known as 'viscosity'. In engine oils this ranges from 5 to about 30. Some gear oils, as in back axles range up to 85 or more (this is very thick and dense)
Because of the different densities. The density of wood is less than water while the density of a penny is greater than water.
