Alter (a number) to one less exact but more convenint calculations.
Sometimes scientists make a mistake or Miscalculate and need to do the experiment again.
It was important because it tells why the denser material had sunken and the lighter is floating on the surface.
<u>Explanation:</u>
Eventually, after around 500 million years, our young planet's temperature warmed to the liquefying purpose of iron—about 1,538° Celsius (2,800° Fahrenheit). This crucial crossroads in Earth's history is known as the iron fiasco. The iron fiasco permitted more prominent, progressively quick development of Earth's liquid, rough material.
We also know that at one point all the material in the planet was molten because the denser material had sunk and the lighter was floating.
a) Simply calculate projection: F.Jake.x=120 cos(32)=101.77 N
b) Likewise: F.Jake.y=120 sin(32)=63.59 N
c) F.N - W + F.Jake.y = 0, so
F.N = W - F.Jake.y = mg - F.Jake.y = 161.81 N
