Which are characteristics of electromagnetic waves? Check all that apply. 1. travel in straight lines and can bounce off surfaces
2. travel through space at the speed of light
3. travel only through matter
4. travel only through space
5. can bend around objects
6. move by particles bumping into each other
5. move by the interaction between an electric field and a magnetic field

come closer and become far apart and become steam/gas

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.

c) up is the direction the magnetic force is acting on the charge.

d) physical means can be used to separate the components of air.
