Volcanic dust, ash from fires, microscopic organisms, mineral particles lifted from soil by wind, pollen from plants, particles from meteors that have been vaporized and cement dust.
You have seven different digits (symbols) to choose from, so you can form seven different one digit numbers and 7×7=72=49 different two digit numbers.
In words; 'Sixty seven thousand'. Inscientific notation 6.7 X 10^(4). By addition 60,000 + 7,000
It means something is done twice (usually on different days) in one seven day week.
There are 7 combinations. Each combination excludes a different one of the seven numbers.
100/7 = 14.2 therefore the answer is 14 (for the numbers 14,28,42,56,70,84,98)
particulates or carbon particulates is a solid pollutant which clog up airways and you get get respiratory diseases or conditions for sufferers get worse
We use DC voltages in an electrostatic precipitator (ESP) because it is necessary to induce a charge on the particulates, and then attract them to a plate by the use of an opposite charge. An AC source would be changing constantly. That would leave our particulates picking up "different charges" at different times as they pass the plates. Further, these particulates wouldn't be attracted to the plates because the plates would be changing polarity as well. ESP's use a DC source to apply a charge of a given polarity to the particulates in the air stream, and use a plate of the opposite charge to attract and "hold" the particulates. AC sources can't do that.
A short definition: separation of solid particulates from liquids and gases using different types of filters.
The particulates accumulate in the lung tissue causing massive irritation

I do not think that word (particulates) means what you think it means. Please check, and repost your question.
by air
The metamorphic or igneous rock would have to be weathered and eroded until it is only particulates. Those particulates must then be forced together as a layer under gravitational pressure. These particulates will then become sedimentary rocks.
Particulates have physical characteristics--solidity and small particle size--rather than chemical ones. Particulates can be elements, compounds, or mixtures.
