The electrolyte in a typical wet storage cell or battery is a mixture of water and

Sulfuric acid.

Explanation:

A battery is a device which contains one or more electrical chemical cells which are connected in a electrical circuit to power the objects like flashlight, speaker, etc.

When a battery is supply electric power then its positive terminal classified as cathode and negative as anode.

And as we know that the electrolyte in a typical wet storage battery or cell contains 67% water and 33% of sulfuric acid.

explanation:

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.
