1 answer:
Rocks within Earth both expand and contract as P waves pass
Explanation:
Rocks within the earth both expands and contracts as P-waves passes through them. P-waves are elastic waves.
Elastic waves behaves in such a way that they do not cause permanent deformation of rocks. They can be said to cause elastic deformation when they travel through rocks. They simply temporarily expand and contract the rock within a short period by causing the vibration of particles of the medium. After a short while, the rock returns back to its original position as if nothing has happened to it. These elastic waves are better called seismic waves. P-waves are primary waves that can travel through any medium.

I think the answer would be 70
Here
Pressure=1000Pa
Area=0.2m Square
Force=?
Now,,
Pressure =force / Area
1000=force/0.2
force=1000/0.2
Therefore,Force=5000N
Human lack chlorophyll , which is the function that collects energy from the Sun to conduct photosynthesis.
That is called a physical trainer or a fitness coach. Hope I helped!
