Superfine 40 gauge copper wire has a diameter of only 0.080 mm and weighs only 44.5 g/km. Suppose it’s full of 40 gauge wire weighs 471. g Less after some wire is pulled off to wind a magnet. How could you calculate how much wire is used?Set the matter. But don’t do any of it. Just leave your answer as a math expression. Also be sure your answer includes all the correct unit symbols.Length of wire = ?

Respuesta :

- To calculate the length of wire we can use a mathematical Rule of Three:

[tex]\text{length of wire=}\frac{wire\text{ weighs. 1km}}{44.5g}[/tex]

- So, in this case the length would be:

[tex]\begin{gathered} \text{length of wire=}\frac{\text{471g.1km}}{44.5g} \\ \text{length of wire=10.58km} \end{gathered}[/tex]

We can write the math expression as:

[tex]L=\frac{w.1\operatorname{km}}{44.5g}[/tex]

Here, L is the length of wire and w is the wire weighs.
