Consider the window crank below - note that it's components are not necessarily orthogonal Given the following: lies in the yz plane lies in the xy plane The angle between and the x-axis is = 19 is parallel to the z-axis Length of = 2.1 cm Length of = 2.1 cm Length of = 1.05 cm = 29 Matlab input: t = 19; a = 29; ab = 2.1; bc = 2.1; cd = 1.05; Determine the position vector, , from to:

An  atom  (ours, not carroll's) consists of a positively charged  nucleus, surrounded by one or more negatively charged particles called  electrons. the positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen. although the nucleus is heavy, it is quite small compared with the overall size of an atom. the radius of a typical atom is around 0.1 to 0.25 nanometres (nm), whereas the radius of a nucleus is about 10-6  nm.  *  if an atom were enlarged to the size of the earth, its nucleus would be only 200 feet in diameter and could easily rest inside a small football stadium.read more on -

For me a person with a phd and who knows what there talking about.i know the chances of a radiation leak is low but if it does the area within a 96.3 mile radius would be unusable because of contamination
