Hmm..I think phd is the best way to prepare for a research-based career, and if i have the choice, I would definitely do it once and twice.. I just like being a phd student!

Hi,, I like this post and all comments,, I need classes in programming or just C++ for beginners,, best if distance-learning, well.. I've never done any of CS, but can you manage to self-study the course, or an instructor always better?Thanks

thanks Mr. BoundByAxioms for your correcting :> I hope the best for all

yah that is clearly ... thank you Mr.LowlyPion for your helping there are small thing also , from where you find this A/2pi*U^2 (U?) ?

why (h) doesn't appears in the last result? yah I understand you .. but your result or the weight of cylinder should be depend on all the variables as the Q. [Find the weight of the cylinder in terms of g, h, A, L, and S.(S or p is density)] pleas can you explain >>> thank you...

point A and point B I take them in same level where A under the cylinder directly and B in versus side >> Hi misters; anybody can help me, please

Homework Statement a U-tube with cross-sectional area A and partially filled with oil of density S. A solid cylinder, which fits the tube tightly but can slide without friction, is placed in the right arm. The system is in equilibrium. Find the weight of the cylinder in terms of g, h, A, L...

Hmm in the drawing is theta the same as angle BOA? Well either way it's BOA or half of BOA due to symmetry so you can find BOA easily and divide if you have to. sorry , my explanation not clearly anyway now I understand used cosine law directly and I don't need analysis all angles...

yes ,, look at attachment the picture is clear that explanation I calculat it by using simple way but How to use cosine law to giveangle theta in pecture an thanks Mr.HallsofIvy

hello , How are you all? look at this question what the magnitude of the angle that between two ribs from the heads of the cube to its center ? I attempted by using cosine law [look at the pecture in attachment] but, Hwo to apply this law on the cube (3D)? any one help me >>and thank you...
