A cylinder with rotational inertia i1=2. 0kg⋅m2 rotates clockwise about a vertical axis through its center with angular speed ω1=5. 0rad/s. A second cylinder with rotational inertia i2=1. 0kg⋅m2 rotates counterclockwise about the same axis with angular speed ω2=8. 0rad/s. If the cylinders couple so they have the same rotational axis what is the angular speed of the combination? what percentage of the original kinetic energy is lost to friction?.

The correct answer is b, social stratification is needed for a society to exist. marxist theory regarding social stratification is that due to the differing economic capacities among people in society, a natural separation occurs between those that own the means of production and those that sell their labour in the production chain. 

Iwas in a argument about a certain class grade with my teacher. it was a ‘a-’when i felt that i deserved a ‘a’. i showed him (my teacher) why i felt i derserved so. i questioned what i got wrong and showed him what i learned. i look back to that teacher with nothing but love and support because that’s the class that i actually learned the most. the moral of the story is to see where the other person is coming from and what they have done. also, when in a conflict, never attack the persons character. this will just make the argument end poorly.
