How much work does an ideal battery with a 7.70 V do to an electron that passes through the battery from the positive to the negative terminal?

W = 7.7 eV

Explanation:

We need to find the work done by an ideal battery with a 7.70 V to an electron that passes through the battery from the positive to the negative terminal.

Let W is the work done. Work done by moving a charge is given by the formula as follows :

W = qV

Here, q = e

W = eV

W = 7.7 eV

So, the required work done is 7.7 eV.

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.
