Applying potential difference to a conductor, by potential force, free electrons gain energy and move from low to high potential. Thus, electrons move from one atom to another.
Depends really. Have you got prior coding experience? The semantics of certain languages are much easier to pick up if you've had prior experience, but it might seem impossible to someone who has minimal experience.
Assuming that you're no older than 15 or 16, I'm going to suggest Python. It's a simple, high-level language that's easier to understand than most languages. If you think you've got enough experience to quickly understand and pick up things, then I'd probably say R is a good language to start with. It's very well-suited for AI and tends to be a favourite for AI researchers.
Answer:
C. Rulers indicate the margins, tabs, and indents in a presentation slide.
Explanation:
The status bar appears at the bottom of the page, and it never displays options the options to style the slides. And the toolbar never displays the thumbnails of the slides, as well as the document area never provides a list of the commands for creating, formatting or editing the presentations. However, the rules do indicates the margins, tabs, and indents in a presentation slide. Hence C. is the right option.
