Answer:
why do the layers of sedimentary rocks parallel to earth's surface?
Why are sedimentary rocks found on or close to Earth's surface?
Explanation: Erosion breaks existing rocks and turns them into sediments. ... When subjected to heat and pressure deeper in the earth sedimentary rocks are changed into igneous and metamorphic rocks. Because erosion only happens on the earth's surface sedimentary rocks are only formed on the earth's surface.
Explanation:
Why do sedimentary rocks have layers and how these layers are formed?
The different groups of sediments could have been deposited through wind, water, ice, and/or gravity at different intervals of time and compacted on top of each other, until they create a sedimentary rock that has several different types of sediments (possibly from different rock types) in the form of layers.
Answer:
All these particles behaves like small magnets which is known as domains
Explanation:
As we know that iron is a ferromagnetic substance so in this type of ferromagnetic substance all the medium particles will behave like small magnets which is known as small domains.
These domains have their own magnetic field which is very weak but if all the domains will align in same direction then all domains will combined and give strong magnetic field.
So in general case when iron nail is placed at room temperature then all these domains are randomly arranged and they do not give any net magnetic field while if we place the iron nail in external magnetic field then in that case the domains will align itself and give strong magnetic field in the direction of external field.
This is known as magnetization
Answer:
electric current through a wire coil
?
Explanation:
The force = 0.3 * 9.8 = 2.94
x = 0.13
k = 2.94/0.13
k = 22.6 N/m
