Whether or not you have 9 Ohms, depends on the resistance per unit length, and of the material of the wire, not on the number of turns.
You should be able to get the appropriate numeric data from a reliable encyclopedia, or from a source of electrical tables.

For wire gauge, 1.25 mm diameter wire is closest to 16 gauge (AWG). See related link.
Probably 19 gauge, which is 1.067 mm
14SWG copper wire has a diameter of 1.628 mm.
A 6 mm earth wire can be used to replace a 2.5 mm earth wire, but if there is an existing 6 mm earth wire it must be 6 mm all the way to the earth, and not replaced by a smaller wire between it and the earth connection.
No, the wire with a diameter of 0.01 mm will have higher resistance compared to a wire with a diameter of 0.1 mm. Resistance of a wire is inversely proportional to its cross-sectional area, so a thinner wire will have higher resistance.
It will taken 8 amps <<>> The conversion of 2.5 sq mm wire to AWG is equal to a #12 wire. The ampacity of a #12 copper wire with an insulation factor of 90 degrees C is 20 amps.
In electrical wire sizing, a 3.0 mm² wire is larger than a 2.0 mm² wire. The numbers refer to the cross-sectional area of the wire, with a higher number indicating a thicker wire that can carry more current. Thus, 3.0 mm² wire has a greater capacity and is typically used for higher power applications compared to 2.0 mm² wire.

For a wire classified under American Wire Gauge standards, 26 gauge wire is 0.0159" (0.40386 mm) in dameter. For a wire classified undere metric wire gauge standards, a 26 gauge wire is 2.6mm in diameter. Metric gauges are calculated simply by multiplying the diameter, in mm, by 10 and therefore increase as the diameter increases, unlike the AWG standard.
R = rho * L / pi r^2 So L = pi r^2 R / rho r = 0.400 X 10^-3 m R = 100 ohm rho = to be noted in a data book Plugging these known values we can compute the value of length in meter'
10 AWG wire will have less resistance per foot and therefore you can have longer runs with 10 AWG than 12 AWG without as much loss of signal. Additional to loss of signal there is a need to maintain a low impedance driving the typical speaker with its 4 ohm or 8 ohm coil resistance, to avoid frequency-distortion. A guide rule is that the speaker cable should have a total resistance around 1% of the speaker resistance (or less). On that basis, for 5 yards of speaker cable for a 4 ohm speaker the wire size would be 4 sq. mm (11 AWG) or for an 8 ohm speaker 2 sq. mm (14 AWG). <<>> Using the above formula of 1% of the speaker resistance the above answer is not correct. For a 4 ohm speaker at 1% is .04 ohms. The resistance of #12 wire is .001588 ohms per foot. This will allow you to run 25 feet and still stay within the parameters. For a 4 ohm speaker at 1% is .04 ohms. The resistance of #10 wire is .00100 ohms per foot. This will allow you to run 40 feet and still stay within the parameters. You can see, what the first answer states is correct.
