Compute the equivalent resistance of the network in the picture and find the current in each resistor. the battery has negligible resistance. req = what is the current through the 12ω resistor? what is the current through the 4ω resistor? what is the current through the 3ω resistor? what is the current through the 6ω resistor?

the gas collects in coils that then becomes a liquid that then flows through the coils inside the refrigerator

iron would move it is magnetic there is a mag field around the current in the wire

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.

i will answer your question if you answer mine
