What type of circuit is illustrated? short circuit series circuit parallel circuit open circuit One end of a battery is connected to lightbulb one by a length of wire. Lightbulb one is connected to lightbulb two by a length of wire. Lightbulb two is connected to lightbulb three by a length of wire. Lightbulb three is connected to the opposite end of the battery with a length of wire.

It's a series circuit.

Explanation:

Series circuit is defined as having only one path through which current can flow.

0.55x745.7j and a calculator

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.
