It, along with the down quark, forms the neutrons (one up quark, two down quarks) and protons (two up quarks, one down quark) of atomic nuclei. It is part of the first generation of matter, has an electric charge of + 2 / 3   e and a bare mass of 7000220000000000000♠ 2.2 +0.5 −0.4  ...

2 Can you partially 'clay' a car, only claying the problem areas? Or will you see differences in the end result (after waxing) between area's clayed and not clayed? I'm just starting in car detailing. I've never used a clay bar before. detailing share | improve this question edited Nov 23 '18 at 13:31 Pᴀᴜʟsᴛᴇʀ2 ♦ 112k 18 175 375 asked Nov 23 '18 at 13:20 svenema svenema 42 3 ...
