By using Ohm's law, we can calculate the resistance of the wire. Ohm's law states that:
where V is the potential difference across the conductor, I is the current and R the resistance. Rearranging the equation, we get
Now we can use the following equation to calculate the length of the wire:
(1)
where
is the resistivity of the material
L is the length of the conductor
A is its cross-sectional area
In this problem, we have a wire of copper, with resistivity
. The radius of the wire is half the diameter:
And the cross-sectional area is
So now we can rearrange eq.(1) to calculate the length of the wire:
<u><em>About 1,199 </em></u><span><u><em>miles From Burma To North.</em></u></span>
Answer:
The class and order levels are switched
Explanation:
Woese's classification starts with a division in three parts of all the organisms, which is their domain, so according to him there's Bacteria, Archaea, and Eukaryota. After the domain we have the kingdom, then phylum, class, order, family, genus, and species at the end.
We can take the leopard as an example:
Domain - Eukaryota
Kingdom - Animalia
Phylum - Chordata
Class - Mammalia
Order - Carnivora
Family - Felidae
Genus - Panthera
Species - Panthera pardus
