As you sit in a chair at your computer, the chair exerts an upward supporting force n on you, and gravity exerts a downward force fg on you. to a fairly good approximation, n =− fg . is this an example of newton’s third law? choose the true statement. 1.no; n+fg ≈0 is due to the fact that your upward or downward acceleration happens to be almost negligible. 2.yes; the “action” fg must produce a “re-action” n . 3.yes; your velocity happens to be zero. 4.yes; the chair is attached to the earth, so both n and fg are exerted by the earth.

1.No;

n + Fg = 0 is due to the fact that your upward or downward acceleration happens to be almost negligible.

Explanation:

As we know that every action has equal and opposite reaction. When one system is applying action force then its reaction force must be on the other who is apply the action

for example if we push an object then the action force is our push while reaction force is on us due to object which is of same magnitude but in opposite direction.

So action and reaction force must be on two different objects and can not be on same object

so correct answer will be

1.No;

n + Fg = 0 is due to the fact that your upward or downward acceleration happens to be almost negligible.

explanation:

the atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding shells of electrons.

like poles repel so keep pushing north to north and repels funny to see this
