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
0.35294117647 so it would be 0.35
10. G (one box below G; one left of D)
11. F (one box below F)
12. F
13. E to F and A to B
14. C to D and E to F
no diagram 2. sorry can't help with the rest :(
Answer:
-9
Step-by-step explanation:
2x + 5 = -13
subtract 5 from both sides
2x = -18
x = -9
