Ivan pushes a dresser with full drawers across his carpeted floor. what could ivan do to reduce the amount of friction between the dresser and the floor? check all that apply. place some smooth tiles under the dresser remove or turn off sources of wind move the dresser at a slower speed remove the drawers from the dresser

If Ivan wants to push a heavy dresser across a carpeted floor, he should consider removing the drawers from the dresser (they are full and offer a lot of extra weight that could easily be reduced if they are simply removed and would in turn make it easier to move) and he should place smooth tiles under the dresser (this offers less resistance between the floor and the dresser making it move much easier, almost as if it were gliding across ice.)

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 -
