The more surface area there is, the more transactions can happen. Which means that breathing will be easier/faster when you have more alveoli. (Please rate this answer if you have time!)
Answer:
Explanation:
Magnetic field due to current carrying wire at a distance r from the wire is
In our case
where,
I₀ = max current or peak current
and r = h (where h is the height of power line)
put
h ≈ 370m
I₀ ≈ 3KA
Looks like B. Remember the sum is the sum of directions.
