Question

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 205.g less after some wire is pulled off to wind a magnet. How could you calculate how much wire was used? Set the math up. 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.

Answer 1

Answer:

Math expression=      L[m]=   W[g]   /   R[g/m]

answer=4.606Km

Step-by-step explanation:

It is known that the cable weighs 44kg / km therefore if the weight is divided by this amount we can find how much cable length was spent

L=W/R

L= leght of wire used(m)

W=weight used(g)=205g

R= relation between weight and leght(g/m)=44.5g/km=0.0445g/m

L=205g/0.0445g/m=  4606.74m=  4.606Km
