The length of the second copper wire is 1250.4 feet.

Step-by-step explanation:

The length of the first wire, = 750 feet.

Resistance of the first wire, = 1.893 Ω

The length of the second wire =

Resistance of the second wire, = 3.156 Ω

The length of the second wire can be determined by the relation;

=

=

=

   =

= 1250.3962

   = 1250.4

The length of the second copper wire is 1250.4 feet.

hi how are you doing today? if you ever need just tell me

step-by-step explanation:

what are you doing do you need examples of variable questions?

step-by-step explanation:

5a-1=9               bring the one over the =

5a=10                     divide by your variable

a=2

brainliest? ?

here try this one
