Let's imagine a flat Earth (as many still do today *snigger*). Then if a person were falling to Earth, towards the Earth's centre, and had horizontal and vertical components of motion then they would hit the Earth. Essentially this is like throwing a ball off a cliff and the vertical component...

They are all absolutely correct. WRITE WRITE WRITE, even if it seems like crap writing. Just get it out. (I prefer to do this long hand, for some reason.) THEN, when you have done all that, type it up and begin the editing process - add, remove, change words, refine, get your first reader to...

Of course it works. Look at the equations again: B= kI/r if you equate the two equations for the two wires you can see that for B to remain the same at a point in space the current and hence the distance apart are in the same ratio. kI1/r1 = kI2/r2 I1 and I2 are proportional and so are r1...

OR YOU COULD Use the equation: B = kI/r For wire 1: B1 = kI1/x For wire 2: B2 = kI2/(0.3-x) I1 = 1A I2 = 2A The currents are in opposite directions, so the magnetic fields between the wires are in opposite directions. Thus you need to find when: B1 = B2 kI1/x = kI2/(0.3-x) 1/x = 2/(0.3-x)...

Yes, they are falling towards the centre of the Earth with the same speed as a skydiver - that is the vertical component of their motion - but there is also a horizontal component which is the velocity of the rocket or space station or whatever they are in, exactly. The air inside a...

While the core is burning/fusing hydrogen to form helium, there is an outer layer of the star that is non-reacting hydrogen. When the star begins to collapse, because the fusing core has used up all the hydrogen in the core only, the outer layer of non-reacting hydrogen begins to heat up and it...

Well, there is "weightlessness" and there is weightlessness. If you were in space away from any large body, there would be no gravity acting you (to speak of) and hence you would have zero weight. Now, the "weightlessness" astronauts/cosmonauts feel is due to something else entirely. They still...

My goodness, there is so much out there on this one. Here is just a taste. Nazism - http://www.creationontheweb.com/content/view/4908/ Sexism - http://www.creationontheweb.com/content/view/1612/ Racism - http://www.creationontheweb.com/content/view/1675 I'm sure you could find more;) Good luck...

One fantastic way to help cut the fluff from something is to use a feature in Microsoft Word that picks out essential text. Go to the TOOLS menu then choose Autosummarise. This is a great way to make summaries of your text as well. To cut down text, choose the "Highligfht Key Points" option...

The Harvard Referencing System is a fairly common referencing system used at most universities. Here is the link to the guide from UNE: http://www.une.edu.au/tlc/students/publications/referencing.php It's 6 pages long but a good giude because it gives examples for all the different sorts of...

Because of the structure of semi-conductors (4 valence band electrons) when one is excited it lkeaves behind a place where the atom would prefer to have an electron (hence a hole). Unlike metals where the electron is lost to the conduction band and moves along with the voltage provided, the...

Actually, there is a scientist who is challenging Einstein (don't think he is Christian) and his work has not been given a lot of cred. Wish I could remember who it was, but it had to do with adding another constant in there (or something like that). He had a very strange and very foreign...

Ah, wirklich? Ich liebe die Schweiz. Vielleicht hilft es, dass ich Freunden in der Schweiz habe. Wo wohnst du in der Schweiz?

I would say it certainly depends on your teacher and how well they are able to convey and explain the new concepts. If they are a teacher who is stuck in the old syllabus then that will make it hard.

And remember, STRESSED in DESSERTS spelt backwards. Do sport. It is a good outlet for stress, clears the head and gives you exercise and Vitamin D all in one hit. Also, I recommend not giving things up just because it is the HSC year. You still have a life to live. Don't fall into the trap of...

Google knows everything. Just look up: FM versus AM And you get lots of sites to check out. Here's one, for example, that explains it quite well:" http://www.pbs.org/wgbh/aso/tryit/radio/radiorelayer.html and another...

Google "Cathode Ray history" and a heap of sites come up. This one looked partuclarly good - which I got to from Wikipedia. http://members.chello.nl/~h.dijkstra19/index.html Enjoy and good luck.

Now you see, that is where there is a mis-conception about life. You can't really keep things separate and in nice little organised boxes. Maths is a tool that is used in Science (and when you get to Uni you wonder wherther you have walked into a Maths or Physics lecture sometimes). All the...

The Pauli Exclusion Principle is ket to understanding the nature and structure of the electron cloud around the atomic nucleus, partcularly in atoms more complex than Hydrogen. It dictates that each atom must have a different quantum state in order to exist. This principle could then explain...

Ah, writer's block. The age old... Leaving it completely for a while and let it mull over in the back of your mind for a bit. Sometimes not having access or time for writing can be the perfect way to get that tricky scene in your head just right. Another is to just write through it. Write any...
