water flows down a pipe at a constant cross sectional area at point somewhere down the pipe the speed of of water is 7.00m/s and a pressure is 1 50×10^5pa determine the pressure at the hight of 3.00m quizlet​

the answer is to check all of them! they all apply well at least i think so!

it is the second option.

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.
