In which scenario will an athletes wrists be under tension?
a: striking a punching bag
b: lifting a barbell overhead
c: completing a push-up
d: pulling a rope in tug-of-war

I think the correct answer from the choices listed above is option D. Pulling a rope in tug-of-war is the scenario that an athletes wrists be under tension. Tension is a pulling force exerted by one end to the other end. It is an act of stretching or straining. Hope this answers the question.

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 -
