Answer:
B = 2.93 x 10⁻⁵ T
Explanation:
The magnetic field due to a straight long wire carrying a current can be found by using Biot-Savart Law, as follows:
B = μ₀I/2πr
where,
B = Magnitude of the magnetic Field = ?
μ₀ = Permeability of free space = 4π x 10⁻⁷ Tm/A
r = distance from wire = 0.03 m
I = Current = 4.4 A
Therefore,
B = (4π x 10⁻⁷ Tm/A)(4.4 A)/(2π)(0.03 m)
<u>B = 2.93 x 10⁻⁵ T</u>

The answer would be altitude.
Quito has the altitude of 2.850m, while Guayaquil has the altitude of 5m.
This can lead to the vast difference in climates.
The most noticeable difference is that temperature drop with increased altitude.
F<span>or each 1,000 foot rise in altitude, there is a 4°F drop in temperature.</span>
