Hey ! I know for sure A is one of the correct answers i’m working on the rest now
220% of the goal. This is because 500 cans would be 200% but since it’s 550, the extra 50% would equal to 220%.
Answer:
Given:-
The length of copper wire (L) = 270 cm
Area of cross-sectional (A) = 0.030 
and specific resistance (ρ) =
ohm-cm.
Use the formula R=(Specific resistance*L)/A, to calculate the Resistance(R)
then,
ohm
Simplify:
R = 0.0162 ohm =
ohm
Therefore, the resistance of copper wire is,
Ω
V is a real number Because v is 1 which will tell you you came from 7 to 8 which was a 1 jump .
