How do you find the density of a cork

Push the cork underneath using something that's thin and then it won't take as much space and it'll measure a new volume of the cork reads. Then you subtract to get to the cork and volume and then divide the mass by the cork and volume and then you have the density of a cork.

I hope this helped! Have a nice evening.

need to see circuit to get time constant

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.
