Samples of different materials, A and B, have the same mass, but the sample of B is higher in density. Which statement could explain why this is so? A. The particles that make up material A are more closely packed together than the particles that make up material B.
B. The sample of material B has greater volume than the sample of material A.
C. The particles that make up material B are more closely packed together than the particles that make up material A.
D. The particles that make up material A have more mass than the particles that make up material B.

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.
