GGavran replied to the thread Correct statement about a reservoir with an outlet pipe.True. P2-P1=ρgh holds when v1=v2, and as you said in the original post, v1 can not be equal to v2, except in the case when v1=0 and v2=0.

GGavran replied to the thread Correct statement about a reservoir with an outlet pipe.Bernoulli's equation P+ρgh+(1/2)ρv2=const is the logic for analyzing statements (ii) i (iii). The statement (ii)...

Thank you very much for the explanation fresh_42, PeroK, Gavran -
GGavran reacted to JimWhoKnew's post in the thread Finding the number of ways to arrange identical balls in a circle (3 different colors) with Like.
Let's take a closer look at your 2 red balls and 2 blue example. The number of combinations for arranging them in a row is 4!/(2!2!)=6...

GGavran replied to the thread Greatest possible value of a constant in polynomial.If b, p and q are integers then from the post #9 we have: 70=qa0 ⇒ q∈{1,2,5,7,10,14,35,70} 27=pa9 ⇒ p∈{1,3,9,27}. 1/27 is the smallest...

GGavran reacted to songoku's post in the thread Greatest possible value of a constant in polynomial with Like.
I have posted the full question so I don't know about this Sorry but why should we consider the case where the quadratic must have one...

GGavran replied to the thread Greatest possible value of a constant in polynomial.You are right. There are the local maximum and the local minimum. In my opinion, the question only holds for q/p<0.

GGavran replied to the thread Greatest possible value of a constant in polynomial.Try to express b as a function f(y) where y=q/p and f(y)=27y+70(1/y). We can speak about the greatest value of b for q/p<0. If q/p>0...

GGavran replied to the thread Understanding Forces and their Vector Components.Generally, yes. But based on the original post, it is obvious that the vector space does not vary, so here we have only a single vector...

GGavran reacted to WWGD's post in the thread Understanding Forces and their Vector Components with Like.
So, do they use Vector Bundles for these problens?
-
GGavran replied to the thread Understanding Forces and their Vector Components.The only important thing is that every vector (force) must belong to the same vector space, so every vector in the vector space can be...

I tried to combine those 2 formulas but it didn't work. I tried using another case where there are 2 red balls and 2 blue balls only so...
