ies are questionable with regards to other theories of how the Universe was started.but still other theory are unemplored and not at all laid down to public knowledge as it wasnt yet discovered and been proven acceptable..." now hear this man.,when GOD was alone, he was lonely and so he thought of a way where in he could make himself happy so, thus then, he worked out an experiment and there 2 things happend.what was that 2 things? TPG m62 has the answer for that. if i tell you everything,you might again say am answering my own question. so.,find out for your self what theory was that that leads to the answer of how the Universe was form.".if you think my words are meaningless and no bases in the field of science at all,well do find it the right answer to this question of mine if you think you have the better one. remember all and everything in this old and ailling earth is graying just like us. and once were old already,we finally cease without knowing when are we going to be ???

A friend of mine lives on a dirt road and it is nice and smooth right after it is plowed, but after a few days it starts getting these ridges and bumps like small waves that make it impossible to go very fast on, especially in my old car. Why does the dirt road get like this?

I don't understand what the point of taking the Fxy (or Fyx) 2nd partial derivative. I can understand taking Fxx or Fyy, but Fxy seems pointless.

If yes, give an example and if not, explain why not.

Now, given that this is a question as a HW assignment, I would say no because for one object to move one way, it is done by friction on the opposite direction.

HOwever, my friend argues that the direction of friction would be the same as the surface that the object was on. Thus, the table and friction are in the same direction.

I argued that friction force of one object cant be applied to another object....

Can anyone resolve this issue?
