Through an experiment on the roof of a building with height of 44.145 meters the roof with made of steel a ball of copper (50 kg) was pushed by a force 1000 N till the edge of the roof fir a distance of 3 meters. Find the horizontal distance for the ball that will be travelled away from the building?

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 -

This is what a calorimeter is used for simpler ex, to measure calories in food.
