Answer:
Magnetic field experienced = 4.5 × 10⁻⁴ T
Explanation:
The magnetic field around an infinite straight current-carrying wire at a distance r from the wire is given by
B = (μ₀I)/(2πr)
B = ?
I = 20 KA = 20000 A
r = 8.9 m
μ₀ = magnetic permeability = 1.257 × 10⁻⁶ T.m/A
B = (1.257 × 10⁻⁶ × 20000)/(2π×8.9) = 4.5 × 10⁻⁴ T
I think the North Pole
If I understand this correctly
He had their masses and reactivity. I hope this helps.
Dispersion
Explanation:
The best word that describes the phenomenon that gives rise to rainbow is dispersion of light.
Dispersion is the process by which white light is separated into different colors or radiation according to their different wavelength.
- In the atmosphere, rainbow is an arc of different colors that forms in the sky.
- Rainbow forms when light is dispersed by water in the atmosphere.
- When rainbow forms light is separated into its different colors and it can be seen in the sky.
