# A book of weight 18 N is resting on a table. A 12-N box sits on the same book?

What is the magnitude of the normal force acting on the book from the table in Newtons?

Yeah, this should be in Physics.

Anyway, the book (with the box on top) is resting. Therefore the normal force acting on the book from the table is equal to the combined force on the table which is simply the sum of the two forces (i.e. 30 N).

In Newton's table of what where?

This is either a physics question or a mathematics question. Move it to one of those two categories, please. It is not a question concerning literature.

Ah yes. That's easy. The magnitude is 7; 8.5 if there's a strong wind and in Newtons it's 2 Newtons, an Einstein and half of a Planck. Hope this helped.
