Heliox is a helium-oxygen mixture that may be used in scuba tanks for divers working at great depths. it is also used medically as a breathing treatment. a 7.25-l tank holds helium gas at a pressure of 1347 psi. a second 7.25-l tank holds oxygen at a pressure of 358.1 psi. the two gases are mixed in a 7.25-l tank. if the temperature remains the same throughout the process, what is the pressure of the gas mixture in the tank? assume ideal gas behavior.

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.
