Answer:

Step-by-step explanation:



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

5. A slope is a line nevertheless and it keeps changing, while the rise over run is also a slope. This means that the only correct answer can be a 2 dimensional figure.
<span>GH would be the intersection in this case. This is the place where the planes come together. An intersection is where two things come together. This enables an object to create a shape like a box and gives support to the sides that mesh.</span>
