The diagram shows the all of the forces acting on a body of mass m = 8.28 kg. The three forces have magnitudes F1 = 14.7 N, F2 = 25 N, and F3 = 13.3 N, with directions as indicted in the diagram, where θ = 28.7 degrees and the dashed line is parallel to the y axis. a)Write an expression for the x component of the acceleration in terms of the symbols in the problem statement.
b) Write an expression for the y component of the acceleration in terms of the symbols in the problem statement.
c) What is the magnitude of the acceleration, in m/s2?
d) What angle, in degrees, does the acceleration make with the x axis?

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 -
