Super fine 40-gauge copper wire has a diameter of only 0.080mm and weighs only 44.5/gkm. Suppose a spool of 40-gauge wire weighs 600. g less after some wire is pulled off to wind a magnet. How could you calculate how much wire was used?

    Given:

    Diameter of copper wire in the spool = 0.080 mm

    Weight of the copper spool = 44.5 g/km

    Weight lost as a result of using some wire of unknown length = 600 g

    To determine:

    the length of the wire used

    Calculation:

    1 km of the spool weighs 44.5 g

    Therefore, 600 g of spool would correspond to a length

    = 600 g * 1 km/44.5 g = 13.5 km

    Since 1000 m = 1km

    This would correspond to a length of 13500 m

    Ans: Around 13500 m or 13.5 km of wire was used.

    Diameter of the wire = 0.080 mm

    Weight of wire per km = 44.5g

    Weight of wire used to wind a magnet = 600 g

    Therefore, length of the wire used:

    600 g x 1 km / 44.5g = 13.48 km

    The length of the wire used was 13.48 km.
