Consider two concentric cylinders with a newtonian liquid of constant density, r, and constant dynamic viscosity, µ, contained between them. the outer pipe, with radius, ro, is fixed while the inner pipe, with radius, ri, and mass per unit length, m, falls under the action of gravity at a constant speed. there is no pressure gradient within flow and no swirl velocity (i. e., tangential velocity) component. determine the vertical speed, v, of the inner cylinder as a function of the following (subset of) parameters: g, ro, ri, m, r, and µ

the largest known star in the universe is uy scuti, a hypergiant with a radius around 1,700 times larger than the

i dont think you are wrong for wanting to get even with someone who did you wrong.

(i'm an eye for an eye kind of person) but if this person hurt you in a sexual way, i dont suggest doing anything to him. he should be taken to the proper authorities, you could go to jail depending on what you do. if it was something small like your sibling took your spot on the couch, than yea, i would get even with him by taking one of his favorite snacks lol. but i dont suggest you doing anything illegal.
