Ihave a project due in 3 days and i need !
i need 4 more questions about the phases of matter.
i already have the following questions:
1. what are the 3 main phases of matter
2. what is a phase
3. name 3 possible phase changes
include the answers to the question(s)
sorry for asking.
(i didn't know what category to put this in, so i chose physics. don't give me crud for this)

true tan speed = ang vel x radius

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.
