Answer:
The moment of inertia is ![I=\frac{M}{12} a^{2}](https://tex.z-dn.net/?f=I%3D%5Cfrac%7BM%7D%7B12%7D%20a%5E%7B2%7D)
Explanation:
The moment of inertia is equal:
![I=\int\limits^a_b {r^{2} } \, dm](https://tex.z-dn.net/?f=I%3D%5Cint%5Climits%5Ea_b%20%7Br%5E%7B2%7D%20%7D%20%5C%2C%20dm)
If r is ![-\frac{a}{2}](https://tex.z-dn.net/?f=-%5Cfrac%7Ba%7D%7B2%7D%20%3Cr%3C%5Cfrac%7Ba%7D%7B2%7D)
and ![dm=\frac{M}{a} dr](https://tex.z-dn.net/?f=dm%3D%5Cfrac%7BM%7D%7Ba%7D%20dr)
![I=\int\limits^a_b {r^{2}\frac{M}{a} } \, dr\\a=\frac{a}{2} \\b=-\frac{a}{2}](https://tex.z-dn.net/?f=I%3D%5Cint%5Climits%5Ea_b%20%7Br%5E%7B2%7D%5Cfrac%7BM%7D%7Ba%7D%20%20%7D%20%5C%2C%20dr%5C%5Ca%3D%5Cfrac%7Ba%7D%7B2%7D%20%5C%5Cb%3D-%5Cfrac%7Ba%7D%7B2%7D)
![I=\frac{M}{a} \int\limits^a_b {r^{2} } \, dr\\\\I=\frac{M}{a} (\frac{M}{3} )_{b}^{a}\\ I=\frac{M}{3a} (\frac{a^{3} }{8} +\frac{a^{3} }{8} )\\I=\frac{M}{12} a^{2}](https://tex.z-dn.net/?f=I%3D%5Cfrac%7BM%7D%7Ba%7D%20%5Cint%5Climits%5Ea_b%20%7Br%5E%7B2%7D%20%20%7D%20%5C%2C%20dr%5C%5C%5C%5CI%3D%5Cfrac%7BM%7D%7Ba%7D%20%28%5Cfrac%7BM%7D%7B3%7D%20%29_%7Bb%7D%5E%7Ba%7D%5C%5C%20%20I%3D%5Cfrac%7BM%7D%7B3a%7D%20%28%5Cfrac%7Ba%5E%7B3%7D%20%7D%7B8%7D%20%2B%5Cfrac%7Ba%5E%7B3%7D%20%7D%7B8%7D%20%29%5C%5CI%3D%5Cfrac%7BM%7D%7B12%7D%20a%5E%7B2%7D)
Answer:
Explain how sociology will contribute to the understanding of daily life and what is happening within it?
Sociology is the study of society of human being, how they develop and those things put in place for such development
Explanation:
Sociology helps to develop culture, how people interact with one another and this boost the relationship and development as far as human society is concerned.
Fish swimming forward in the water, the water gets pushed backward because the fish moving forward is forcing the water to move backward, the motion forward and backward are the same, they are opposite and equal.
Answer:
if they move to their respective sides at the same time then they are moving at exactly the same velocity
so that means they have the same speed and velocity
