Eli and Andy want to find out which of the two is stronger. Eli pushes a table with a force of 120 newtons while Andy pushes the table from the opposite side with a force of 125 newtons. Ignoring the masses of Eli and Andy, what is the resultant acceleration of the table if its mass is 10.0 kilograms? A.
13.5 meters/second2
B.
0.50 meters/second2
C.
4.0 meters/second2
D.
5.50 meters/second2
E.
1.35 meters/seconds2

B.  0.50 meters/second^2

Explanation:

Given:

mass of table (m) = 10.0 kgEli's force (F1) = 120 NAndy's force (F2) = -125 N

Arranging Formulas and Substituting Values, Part 1:

F = F1 + F2F = 120 + (-125)F = -5 NThe -5 means that the table will move along the direction of the force applied by Andy.

Arranging Formulas and Substituting Values, Part 2:

m * a = Fa = F / Ma = -5 / 10.0 kga = -0.5 m/s^2

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 -
