Two scientists may try to collaborate under Few circumstances :-

Every scientist have their II level of knowledge and creativity on combining two it might result in a better outcome Mistakes of one can be analysed and covered by the other thereby increasing the chances of getting good results.

A rather greatest spectrum of knowledge  would be present as the knowledge of two scientists would always be more than one Which is also true in the case of expertise in more than one subject can be there.  

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.
