darwin observed fossils of glyptodonts, which are now extinct. living armadillos are the only animals remaining on earth that are similar to glyptodonts. armadillos live in the same places that glyptodonts lived. what did darwin most likely conclude about the two types of animals?
glyptodonts were better adapted to the environment.
glyptodonts outcompeted armadillos for food.
glyptodonts were early relatives of armadillos.
glyptodonts had the exact same adaptations as armadillos.

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.
