Answer:
The magnetic field of Earth is caused by currents of electricity that flow in the molten core. These currents are hundreds of miles wide and flow at thousands of miles per hour as the earth rotates. The powerful magnetic field passes out through the core of the earth, passes through the crust and enters space.
Answer:
The coil generates a stronger magnetic field. The coil generates a weaker magnetic field. The field generated by the coil has a different polarity than the field generated by the length of wire.
Explanation: Good Luck!!
Answer:The predicted population of brain coral in a reef covering 120m² is ; ≈ 40
First step : Calculate the value of the default population density
Population density = population size (dive 1) / total area
= 4 / 12 = 0.33
Total area ;
∑ Area of each reef quadrant = length * width = 2 * 2 = 4m²
∴ Total area = 4 + 4 + 4 = 12m².
Final step : Determine the value of the predicted population of brain coral
Population density = ( predicted population ) / predicted area
0.33 = ( pp ) / 120m²
∴ Predicted population ( pp ) = 0.33 * 120
= 39.6 ≈ 40 brain corals
Hence we can conclude that the predicted population of brain coral is 40
