PLS HELP (ASAP) actually give me the answer

You find a ring with a mass of
13.5g. You fill a graduated
cylinder with 10 ml of water and
put the ring into the cylinder. The
water rises to 15 ml. What is the
substance?

the substance is IRON.

like poles repel so keep pushing north to north and repels funny to see this

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.
