a cheap 3000 psi tank can be purchased at your local sporting goods store and is 35-40 dollars.
A good 4500 psi carbon fiber tank can cost upwards of 150 dollars
If you're implying that you're battery run out then it'll depend on the gun you have but most you'll have to open the gun in order to replace the battery, no gun I ever heard of yet can be charged.
yes, any gun that can shoot CO2 can shoot N2, but not always the other way around.
Approximately 78% of the Earth's atmosphere is composed of nitrogen (N2).
Most paintball markers can hold a N2/Nitrogen/HPA/Air tank so I couldn't possibly list them all, if you submit specific markers I could tell you if they fired using Nitrogen.
"Air", "Compressed air", "High Pressure air", "nitrogen", "N2" and "Nitro" are all the same gas, these are just different nicknames for it. The correct term is High Pressure Air, or HPA. Since air is mostly Nitrogen, it is given other names. The Air also contains CO2, but in paintball Co2 is separated pure liquid Carbon-dioxide, which is incompatible with HPA tanks and guns.
approx 80%
78% of the atmosphere is nitrogen.
Very much
These are the two search strategies which are quite similar.In breadth first search a node is expanded according to the cost function of the parent node. In best first search we expand the nodes in accordance with the evaluation function.This can be understood by the given example.Suppose we are at two intermediate nodes N1 & N2.The cost function of N1 is less than that of N2.So the breadth first search will definitely expand N1.Now suppose somehow we have the knowledge about the cost required from reaching goal node from N1 and N2.If the sum of the costs of reaching N1 from Start node and the cost (knowledge) of reaching goal from N1 is more than that of the sum of the costs of reaching N2 from Start node and the cost (knowledge) of reaching goal from N2 , then we should expand N2 and not N1.This expansion is done in Best first search
n2-1 and n2-4 are trivial cases because of n2-m2=(n-m)(n+m). So the only prime of the form n2-1 is 3 and of the form n2-4 is 5.
To convert 14 grams of N2 to NH3, you first need to balance the chemical equation for the reaction (N2 + 3H2 --> 2NH3) and calculate the molar ratio between N2 and NH3. Then you can use this ratio to determine the amount of NH3 produced.
The formula for the sum of the series r(1/n2-1/n2) is r(1-1/n2).
