can somebody pls explain what is metacentre?

Reference #1:\n\n: the point of intersection of the vertical through the center of buoyancy of a floating body with the vertical through the new center of buoyancy when the body is displaced \n\n\nReference #2:\n\nn : (shipbuilding) the point of intersection between two vertical lines, one line through the center of buoyancy of the hull of a ship in equilibrium and the other line through the center of buoyancy of the hull when the ship is inclined to one side; the distance of this intersection above the center of gravity is an indication of the stability of the ship [syn: metacenter]

Orthocentre = point where altitudes intersect (An altitude is the line from the vertex to the opposite side (extended if necessary))\n\nIncentre = centre of the incircle = point where perpendicular bisectors of each of the sides intersect. \nRadius of incircle = √[(s-a)(s-b)(s-c)/s] where s = semiperimeter\n\nCentroid = point where medians meet (Median is the line joining a vertex to the midpoint of the opposite sides) The centroid is the centre of gravity of the triangle and the centroid divides each median in the ratio 2:1 On a numberplane the centroid of a triangle is the point which is at the average of the sum of the three x- and y-coordinates of its vertices)\n\nOne other is:\nCircumcentre = centre of the circumcircle = point where angular bisectors meet.\nDiameter of circumcircle = a/sinA = b /sinB = c/sinC

You can't balance it because you don't know what it yields.\n\n\nP.S. This needs to be in the chemistry category. You really must not know much about chemistry and physics.

Optical isomerism is the phenomenon by which certain compounds rotate the plane of polarised ligth in a characteristic way when it is passes through their solutions.\nEnantiomers are stereoisomers that are related to each other as non-superimposable mirror images.Such stereoisomers differ only in the orientation in which they rotate the plane of polarised light.\nA mixture of two enantiomers in equal proportions have zero optical activity(racemic mixture)

Maybe you are referring to the "Hayashi Track" that protostars move along prior to reaching the main sequence. The question is a little vague, so  I am unsure. Here is the wiki link.  \nhttp://en.wikipedia.org/wiki/Hayashi_track

what I know is that its a special machine that can magnify the elements to nanometers where you are able to see it. If you used this machine on lets say a NaCl crytyl lattics, you would see the solid as Na+ ions and Cl- ions coming together in an organized lattice.

I don't understand what you are talking about.  Give more info.

Hi there,\n\nTry looking for "Klein space" (without the 's). You get for instance this page : http://www.mccallie.org/myates/The%20Shape%20of%20Space/Student%20Projects/group10.htm

It is hard to explain here. \n\nIt is a hypothetical particle predicted by standard model of particle physics. And it was originally predicted by Peter Higgs.

Microsoft Windows Metafiles are image files that can contain both vector and bitmap-based picture information. Microsoft Windows contains routines for displaying various Windows Metafile formats. However, a lack of input validation in one of these routines may allow a buffer overflow to occur, and in turn may allow remote arbitrary code execution.\n\nHope this helps!

A circumcenter is the center of a circumscribed circle, which is a circle that contains a polygon inside.  The vertices of the polygon are all on the circle.  The circumcenter is the center of this circle.\n\nAn orthocenter is the intersection point of the 3 altitudes of a triangle.  To draw an altitude, you draw a line from one vertex perpendicular to the base on the other side.  These altitudes intersect @ one point, the orthocenter.\n\n-----------\n\nHope this helps

N2+ is a meta director because it's positively charged. If something added o/p, there would be a +charge next to the already +ve N2, which is very bad. NH2 is an o/p director, because it has lone pairs which help stabilise an adjacent +charge.\n\nAbout toluene - it all depends on the relative strengths of the directing, so there's no general case, though resonance effects will usually take precedance over inductive effects.
