Our planet's magnetic field is believed to be generated deep down in the Earth's core. The Coriolis force, resulting from the Earth's spin, also causes swirling whirlpools. This flow of liquid iron generates electric currents, which in turn produce magnetic fields.
Hope this helps!
Answer:
There is one scientific method
it starts with an
OBSERVATION
then a HYPOTHESIS
which goes to planning, creating an EXPERIMENT
and finally a conclusion for your results
Explanation:
The chemical formula of a compound express the atoms by which the molecule is formed and the ratio of the atoms in which they are combined.
The space filling model of a compound describe the electron density in the compound of each atom.
The ball and stick arrangement of a compound describe the way in which the molecules are present in three dimensions.
The structural formula state the number of atoms present in the molecule, the type of element or atom present in the molecule and the way in which they are arranged closely which is the bond.
Thus only the structural formula only will cover all the options as stated.
The volume of 6.00g iron is 0.762 cm^3.
<em>Step 1</em>. Calculate the <em>density of Fe</em>
The <em>specific gravity</em> (SG) of a substance is the ratio of its density to the density of water at 4 °C.
SG = density of substance/density of water.
∴ 7.87 = density of iron/1.00 g·cm^(-3)
Density of Fe = 7.87 × 1.00 g·cm^(-3) = 7.87 g·cm^(-3)
<em>Step 2</em>. Calculate the <em>mass of Fe</em>
Volume of Fe = 6.00 g Fe × (1 cm^3 Fe/7.87 g Fe) = <em>0.762 cm^3</em>
