students have two samples of uranium that they know were pure at some point in the past, and they wanted to determine which sample is older. an analysis reveals the percentage of uranium-238 and lead 206 contained in each sample, as shown in the circle graphs. based on these data as well as the uranium 238 decay series, which sample can the students conclude is older?​

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.

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
