ANSWERS
(b) Graph:
(c) 25
EXPLANATION
(b) To graph the results, we have to graph each point. The x-coordinate is the number of coils and the y-coordinate is the resistance,
And then, since this is linear, we can join the points with a line.
(c) Now, we have to draw a horizontal line where the resistance is 10 Ω, and then a vertical line from where this line intersects the graph,
Hence, the number of coils for a resistance of 10 Ω is 25 coils.
