Arrange the events in the correct order to describe how the magnetic field forms around Earth.
horsena [70]
The correct sequence of events is : C,D,B,A.
Iron rich magma in the earth's core heats up because of radiation and the pressure exerted by the other layers of the earth. This heat in the crust trigger convection currents in the mantle. The magma closest to the core will be hotter and therefore less dense than other layers. Being less dense the layer will rise towards the crust, eventually becoming cooler and sinking back down in a circular motion.
The continued circular motion creates electric currents which then generates the magnetic field.

4. If index of refraction 1 is 1.5, index of refraction 2 is 2.0, and the angle of incidence is 45 degrees, what is the angle of
motikmotik

Answer: The angle of refraction is 32°

Explanation:

By snell law, we have that:

n₁*sen(θ₁) = n₂*sen(θ₂)

Where n₁ = 1.5

n₂ = 2.0

θ₁ = 45°.

then we want to find the angle of refraction.

1.5*sin(45°) = 2*sin(x)

x = Asin(1.5*sin(45°)/2) = 32°
