Earth’s magnetic field is generated in the core, which is made of ( IRON) that is constantly (MOVING)i got it right <span> .

We will apply:
Q = mcΔT; where Q is the heat, m is the mass, c is the specific heat capacity and ΔT is the temperature change.
30,000 = 390 x 3.9 x ΔT
ΔT = 19.7 °C
The temperature change is of 19.7 °C.
1. A Medium
2. One of these 4, the refractive index of the medium <span>Choose whichever are on the test.
3. </span>properties and nature of medium, Hope this helps.
We would need to know the time it took to slow to a stop.
Steps of a scientific investigation include identifying a research question or problem, forming a hypothesis, gathering evidence, analyzing evidence, deciding whether the evidence supports the hypothesis, drawing conclusions, and communicating the results.
