What is the resistance per meter of an gold wire with a cross-sectional area of 2.4×10−7 m2 .
I used ----- (Resistance)/(cross sectional area) and (2.44* 10^-8) / (2.4 *10^-7 )
but it is wrong... Thank you for the help in advance!

Calculate the resistance of a piece of 20-gauge gold wire 2.20 m long. The cross-sectional area of 20-gauge wire is 0.5176 mm2. Resistivity for ("calculator" notation, in ohm*meter) - aluminium: 2.65 e-8 copper: 1.72 e-8 gold: 2.24 e-8 iron: 9.71 e-8 nichrome: 1.00 e-6 platinum: 1.06 e-7 silver: 1.59 e-8 tungsten: 5.65 e-8
A copper wire of length 1 meter, cross sectional area 7.1 X 10‑6 m2 and Young’s modulus 11 X 1010 N/m2 has a mass load hung on it. If its increase in length is 1 mm, what is the value of the mass? a) 40kg b) 80kg c) 200kg d) 400kg e) 800kg Please help me. Thank you
has Conductor 1 meter Length with cross-sectional area of Imm² and a resistance of gose. - what is the resistance of wire from the material and with a Cross sectional area of o. 25mm?? 100 meters Length of same
What is the resistance of a copper wire 1.2 m in length whose cross-sectional area is 3.0 x 10-6 m2 at 35oC?
Copper contains 8.4 Times 10^28 free electrons per cubic meter. A copper wire of cross-sectional area 7.4 Times 10^-7 m^2 carries a current of 1 A. What is the electron drift speed?

Please answer this question: An aluminum wire having a cross-sectional area of 2.10 ✕ 10−6 m2 carries a current of 6.00 A. The density of aluminum is 2.70 g/cm3. Assume each aluminum atom supplies one conduction electron per atom. Find the drift speed of the electrons in the wire. Please answer correctly!!!! Thank you so much in advance!

You are working at a company that manufactures electrical wire. Gold is the most ductile of all metals: it can be stretched into incredibly long, thin wires. The company has developed a new technique that will stretch 1.00 g of gold into a wire of length L= 2.40 km and uniform diameter. a) What is 1 gm in kg, and what is the volume of 1 gm of gold? The mass density of gold ρ= 1.93 x 10^4 kg/m3. Watch...
1. What is the resistance of a 450 m long copper wire that has a cross-sectional area of 3.00 x 10–6 m2?
A thick copper wire 2.3 m long is connected in series to a thin high-resistance Nichrome wire. In the steady state, the conventional current in the thick copper wire is 4 amperes. In this copper wire there are 8 � 1028 mobile electrons per cubic meter and the electron mobility is 4.5 � 10?3 (m/s)/(V/m). The cross-sectional area of the copper wire is 6 � 10?7 m2. The thin high-resistance Nichrome wire (which is connected in series to the thick...
