It is a gas. Gases can easily change volume and always fill the whole container.
Answer:
Each layer has its own properties, composition, and characteristics that affects many of the key processes of our planet. They are, in order from the exterior to the interior – the crust, the mantle, the outer core, and the inner core.
Explanation:
Answer:
The extent to which it would stretch is 
Explanation:
From the question we are told that
The initial length is 
The area is 
The Young modulus of the steel is 
The tension is 
The Young modulus is mathematically represented as
Where 
is the stress which is mathematically represented as
Substituting values
And e is the strain which is mathematically represented as
Where 
The extension of the steel string
Substituting these into the equation above
Substituting values
In the first figure, the surface absorbs all colors except for green light, which is reflected: so, the surface will appear as green to our eyes, because green is the only color which is reflected by that surface.
Similarly, in the second figure, the surface absorbs all colors except for blue, and so the surface will appear blue to our eyes.
In the third figure, the surface absorbs all colors, so it will appear black to our eyes (because no colors are reflected, and black=absence of colors).
In the fourth figure, all colors are reflected: this means the surface will appear white to our eyes (white= sum of all colors).
