According to meteoric material, the solar system was formed around <u>4.6 billion years</u> ago.
<h3>What substance makes up a meteorite?</h3>
- With just trace levels of sulphide and carbide minerals, they are primarily composed of iron-nickel metal.
- Many asteroids melted during the radioactive element decay in the early solar system, and the iron they carried, being dense, sank to the centre to create a metallic core.
<h3>What is the term for meteorite metal?</h3>
- Meteoric iron, also known as meteoritic iron, is a native metal and a protoplanetary-disk remnant from the early universe that is found in meteorites.
- It is mostly composed of the metals iron and nickel, primarily in the crystalline phases kamacite and taenite.

Answer:
35000kg
Explanation:
the answer is 35000
F=m1v2/m2v2
m1=0.420kg
v2=2.00
m1=?
v2=6.00
F=40.0
40.0=0.420*2.00/m2*6.00
m2=0.84/240
m2=<em>3</em><em>5</em><em>0</em><em>0</em><em>0</em><em>/</em><em>/</em>
The answer is noble gas. Since noble gas are constant and
unreactive. They can still shape compounds with other elements.
Group 15 is also group 5A and Group 17 is also group 7A. Elements in these sets
do not typically form ionic bonds; they are more on creating covalent bonds
since they're non-metals.
Therefore, that leaves us with B. from Group 1. They are metals (but Hydrogen)
which respond violently with water, and they form ionic bonds, for they drop
outer electrons easily.
Answer:
Explanation:
Edit to add part a
a) Heating a gas causes the atoms to increase their kinetic energy. With only atmospheric pressure to contain it, the gas will decrease in density by pushing colder gas out of the way. The lid is then sealed to the jar and allowed to cool. The cooling gas, now constrained by the volume of the jar will be forced to lower its pressure to maintain equilibrium. The lower pressure inside the jar will allow the atmospheric pressure outside the jar to "click" the lid indicating a proper seal.
b Before opening there is a much lower pressure inside the jar than outside. The outside pressure keeps the lid constantly in the "clicked" position.
c After the jar is opened, the pressure on either side of the lid is equal and an unbalanced force applied to one side of the lid or the other can cause the lid to "click" or "unclick" depending on the initial position.
Answer:
a) Vf = 4.95 m/s
b) t = 0.51s
Explanation:
take downwards as positive.
let Vf be the final velocity as the cucumber reach the bottom of the bin and Vi be the initial velocity of the cucumber when they dropped.
a ) from equations of motion:
(Vf)^2 = (vi)^2 +2g×(x - x0) ,
<em>since x0 = 0 m and Vi = 0 m/s.</em>
Vf = \sqrt{2g×(x)} = \sqrt{2(9.8)×(1.25)} = 4.95 m/s, downwards
therefore, the cucumber will reach the bottom of the bin with a speed of 4.95 m/s.
b) from equations of motion:
Vf = Vi + g×t
Vi = 0 then:
t = Vf/g = 4.95/9.8 = 0.51 s
therefore, the cucumber will take 0.51 seconds to reach the bottom of the bin.
