What are the components of vector b if its magnitude is 18 m and makes an angle of 112° with the +x-axis? bx  = −6.74 m,  by  = 16.7 mbx  = 6.74 m,  by  = −16.7 mbx  = 16.7 m,  by  = −6.74 m

Calling B=18 m the magnitude of the vector, its components on the x- and y- axis are given by:


Therefore, the correct answer is the first one:
Bx = −6.74 m, By = 16.7 m

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 -
