As waves pass through matter, whether it's a gas, solid, liquid, etc., this matter on a molecular level is displaced (the molecules are displaced) and this translates to kinetic energy.
Answer:
Mechanical weathering is the physical breakdown of rock into smaller pieces. Chemical weathering is the breakdown of rock by chemical processes.
Explanation:
Mechanical weathering (also called physical weathering) breaks rock into smaller pieces. These smaller pieces are just like the bigger rock, just smaller. That means the rock has changed physically without changing its composition. The smaller pieces have the same minerals, in just the same proportions as the original rock.
Chemical weathering is the other important type of weathering. Chemical weathering is different from mechanical weathering because the rock changes, not just in size of pieces, but in composition Chemical weathering works through chemical reactions that cause changes in the minerals.
Answer:
The net magnetic field ta the center of square is
.
Explanation:
Current, I = 12 A , side ,a = 10 cm = 0.1 m
Let the magnetic field due to the one side is B.
The magnetic field is given by
![B = \frac{\mu o}{4\pi}\times \frac{I}{r}\times \left (Sin A +Sin B \right )\\\\B = 10^{-7}\times \frac{12}{0.05}\times \left ( sin 45 + sin 45 \right )\\\\B = 3.4\times 10^{-5} T](https://tex.z-dn.net/?f=B%20%3D%20%5Cfrac%7B%5Cmu%20o%7D%7B4%5Cpi%7D%5Ctimes%20%5Cfrac%7BI%7D%7Br%7D%5Ctimes%20%5Cleft%20%28Sin%20A%20%2BSin%20B%20%20%5Cright%20%29%5C%5C%5C%5CB%20%3D%2010%5E%7B-7%7D%5Ctimes%20%5Cfrac%7B12%7D%7B0.05%7D%5Ctimes%20%5Cleft%20%28%20sin%2045%20%2B%20%20sin%2045%20%20%5Cright%20%29%5C%5C%5C%5CB%20%3D%203.4%5Ctimes%2010%5E%7B-5%7D%20T)
Net magnetic field at the center of the square is
B' = 4 B
![B'= 4\times 3.4\times 10^{-5}\\\\B' = 1.36\times10^{-4} T](https://tex.z-dn.net/?f=B%27%3D%204%5Ctimes%203.4%5Ctimes%2010%5E%7B-5%7D%5C%5C%5C%5CB%27%20%3D%201.36%5Ctimes10%5E%7B-4%7D%20T)
