Help With Physics Project Please?
You need to find a way to store mechanical energy which can be transferred to kinetic energy at will. A spring is a great, simple way to do this. A torsional spring (the kind you twist, not squeeze from end to end) can be wound up and "set." If you used this concept and mounted a torsional spring on the axle of your cars' rear (or front) wheels you can have the spring directly drive the car. Set the spring by tensioning up the torsional spring (twisting it in the direction to make the spring wind tighter) and then using a stop of some sort to keep the thing from unwinding immediately. (An example would be to put a small pin through the axle that will hit against the body of your car & keep it from unwindin until you remove the.) Then when you are ready for your car to move you can pull the stop that has set your spring and let the unrolling action of the spring turn the shaft your wheels are on. woooosh... there goes your car.

I have a html file saved as file:///Users/Name/Desktop/File.html - How do I make this a public link?
From your question i deduce you are just starting on computer concepts.This is a bit more complex than you might have imagined.You first need to understand how looking at an html file basically works.It involves theese steps:1 - a user, anywhere in the world with internet access, opens up his browser and types in a url. 2 - the browser understands that url as the ip address of the html doc you want to access and the doc name. How it understands it is a bit complex and not really important at this point. An ip address is an address used to locate computers on the internet. For example when you type www.example.com/index.html. The browser decodes www.example.com into a ip address like 132.278.10.245 and it understands that you want the doc named index.html located in the computer with that ip address.3 - the browser sends a request to the computer with the ip address asking for the html file you specified. This is done via an http request, just so you start associating terms.4 - the other computer responds with the specified html document.5 - the browser renders (shows) the html document in the user's screen.Ip addresses are a bit tricky.Because for regular users, like im assuming you are, ip addresses change with time. They are called dynamic ip addresses because they tipically change daily.This would make it difficult for a user to find your html document because the address of your computer will be changing from time to time. Difficult not impossible.You have two broad optionsThe first one is making the html doc accessible directly from your personal computer. I wouldnt recommend this. First, it will be a challenge if you are a begginer. It will also make you vulnerable to security attacks, specially if you are not hundred percent sure about what you are doing.The second one is to host the file in a server with a fixed ip address. You could even buy a domain, make it point at your website and have your own public website with your html doc.Both this options are hard for a begginer. You would need to do some serious studying to get any up and running. Maybe not hard but they will take you some time. It will be gratifying though!If you want to go ahead id suggest searching about http requests, web servers and basic networking. PM me and i can give you more in detail advice about how to tackle this challenge.
Can you help me carve out a curriculum for HTML/CSS? I am seriously confused by what is out there.
Keep in mind that it's always easier if you have some task or project in mind to help you learn about these. There's nothing like the fresh feel of success :-)And now to be more concrete, for learning HTML and CSS, I would start with an existing HTML and then trying figuring out how to control the CSS by applying the simplest style (say, background-color: blue) on the different elements. You can read about CSS and ID, CSS and classes, pseudo-classes, to be able to control anything on a given page. You should have a sample HTML file and a CSS file that you can comfortably change. You should use Firebug or Developer Tools to understand the page structure and the different styles and classes [Thanks, Mark Simchock]. I would then read about the Box Model and its different options. You can read a few thorough articles and then experiment with the different options until you get how to lay out content correctly. You should have some basic HTML file (a few nested DIV elements) with a CSS file laying them out. You should be familiar with margin, padding, border, height, width, display, visibility, and maybe a few more. Then, some reading into semantic web will help you figure out which HTML elements to use in a given scenario. Don't read too much about this though as it's a much debated topic. You should familiarize yourself with some basics, for instance, HTML, HEAD, BODY, DIV, IMG, A, P, UL, OL, LI. You can then take a look at some others, such as tables (be careful, they were misused a lot), forms and input fields, new HTML5 elements (header, footer, article, section, video, audio - don't go crazy here), etc.From there you can quite pick any CSS feature and pick it up along the way. Examples: text effects (size, color, font, line-height), web fonts, relative font sizes (aka Ems), transitions, animations, flex box, background images, borders, etc. Each will take you a few good days to get decent at.This should bring you up to speed on HTML and CSS. Now, if you want to build a full-fledged site, you can get a current framework like Bootstrap and figure out how to use it and customize it to your need.Keep in mind that all this is before even introducing JavaScript into the picture, so learning never ends.Good luck.
Doing a school project about witchcraft and background...?
The term "witchcraft" has been used to describe the beliefs and traditions of many groups around the world. The history of superstitions, persecutions, and groups is too lengthy to discuss here. Below are some links to pages that will give you more info. and ideas on what to look up for those answers. This link has information on "The Burning Times" http://www.religioustolerance.org/wic_burn.htm You can google those words and get more information on that subject. This link has a timeline with basic information. http://www.law.umkc.edu/faculty/projects/ftrials/salem/witchhistory.html Of course, this will give you a basic overview. http://en.wikipedia.org/wiki/Witchcraft
