A conducting wire has a diameter of 0.8 mm and resistivity 1.6 x 10-8ohm-m. Calculate the length of this wire required to make a 2ohm coil.

a and c

c is 100% but i am confused in a

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)

+15-35=-20

going in opposite directions
