Resistance = voltage / current.
That's. 120v / 14A = 8.57 ohms.
By the way, voltage doesn't "run through" anything. Current does. That would be the 14 Amps.
<u>Answer:</u> runoff water is water from rain, snow, or other sources, that flows through the land, and is a major component of the water cycle.
The resistance of a given conductor depends on its electrical resistivity (
), its length(L) and its cross-sectional area (A), as follows:
![R=\frac{\rho L}{A}](https://tex.z-dn.net/?f=R%3D%5Cfrac%7B%5Crho%20L%7D%7BA%7D)
In this case, we have
,
and
. So, the total resistance of the wire with length of 138m is:
![R'=\frac{\rho' L'}{A'}\\R'=\frac{\rho 138L}{A}\\R'=138\frac{\rho L}{A}\\R'=138R\\R'=138(0.24\Omega)\\R'=33.12\Omega](https://tex.z-dn.net/?f=R%27%3D%5Cfrac%7B%5Crho%27%20L%27%7D%7BA%27%7D%5C%5CR%27%3D%5Cfrac%7B%5Crho%20138L%7D%7BA%7D%5C%5CR%27%3D138%5Cfrac%7B%5Crho%20L%7D%7BA%7D%5C%5CR%27%3D138R%5C%5CR%27%3D138%280.24%5COmega%29%5C%5CR%27%3D33.12%5COmega)
Since force is mass*acceleration,
F = 70kg * 9.8 m/s
