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.
1/s' = 1/f - 1/s
= 1/12 - 1/8
= 2/24 - 3/24
= 2-3/24
= - 1/24
s'= -24
M= |s'/s|
M = |24/8|
M = 3

B. The recoil is a result of conservation of momentum. The force of the ignition of the gunpowder that pushes the bullet forward will be balanced out by also pushing against the gun.
Newton's third law is displayed in each of these questions.
Answer:
Explanation:
Comet is made by dust particles, icy particles, gases etc.
A comet has a fixed time to complete a revolution around the sun.
As a comet comes nearer to the sun, due to the heat of the sun the vapour and the icy particles becomes gases and due to the radial pressure of energy od sun, we observe a tail of comet which has vapours mainly. SI the comet is visible easily.
