1–16 the pascal (pa) is actually a very small unit of pressure. to show this, convert 1 pa=1 n/m21 pa=1 n/m2 to lb/ft2lb/ft2. atmosphere pressure at sea level is 14.7 lb/in214.7 lb/in2. how many pascals is this?

is 101325.9 Pa.

Explanation:

Given that

We know that

Pascal is the unit of pressure

We know that

So

So we can say that one

is 101325.9 Pa.

i think its

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
