You are right, just amazing!!! Love them.

Sounds like you have a teacher who does not know how to edit. Sorry about that. A good editor does not try to change the voice of the work but helps correct the mistakes that scream "amateur". If you want a non-biassed, non-taking over opinion, I'm here ;) But in any case, keep arguing OR...

And some more??? There was an engineer who had an exceptional gift for fixing all things mechanical. After serving his company loyally for over 30 years, he happily retired. Several years later the company contacted him regarding a seemingly impossible problem they were having with one of their...

Yes: Europe - Switzerland, Germany, Italy, Austria, Slovakia, France, England, Wales, Scotland, Belgium, Monaco, Vatican City USA, New Zealand, Norfolk Island (it's over the sea!), Singapore, Malaysia, Hong Kong stopovers only in Thailand and Japan. Yes, back to German speaking countries and...

Man, does this survey qualify for an entry in the "You *know* your Physics nerd when..." thread!!! But ROYGBIV, all the time. I was just taught it that way.

Hee hee. I just had to add this one. You argue in a topic called "You *know* you're a physics nerd when..." about the number of commas and how nerdy you are. ;) And from somewhere esle I posted: You are being pulled down a hill by your shopping trolley and you are contemplating the vector...

If worst comes to worse and you cannot see yourself catching up in every subject, rather than fail everything and then spend a whole year doing them ALL over again at TAFE or something like that, perhaps it is worth speaking to the HSC advisor at your school and see if you can do Pathways and do...

Ah, vectors. I remember them fondly. But now I look upon them as an everyday thing, especially when I am navigating my shopping trolley down a sloping hill towards the car park. (Truely, I do. Maybe that should go in the "You know your a Physics Nerd when..." thread. hee hee)

Actually, the diagram for both is the same. In the first, mass A hangs vertically, in the second, mass B hangs vertically. Anyway, in question 1. On mass A there are two forces: FGravity = -mg (ie down) FString Tension=T (ie up) Add the forces and the mass is stationary so resultant F=0...

I did German at Uni and School. Watatank is correct. Listen to as much German as you can. Try and watch German shows on SBS, catch the German news on SBS radio if you can, or get someone to tape it for you. You can stream it off the internet as well. That can be good to do, because then you can...

Cathode rays were once thought to travel through the ether. http://www.aip.org/history/electron/jjrays.htm http://nobelprize.org/nobel_prizes/physics/laureates/1905/press.html However, I cannot see how they disprove it. You may have got a tick because the teacher did not know for sure. ;)

The old paper Dick Smith Catalog was my constant companion while doing Electrical Engineering at Uni :D

This is a strange question. What is the actual question?

One place to bookmark and refer to often is this palce: http://webs.mn.catholic.edu.au/physics/emery/accuracy.htm Always remember, accuracy, reliability and validity.

Well, let me see, this is a first aid issue, in some respects. Here are some websites. There is a warning on the first one. It has some graphic pictures that illustrate the danger of electricyt on human flesh: http://www.osha.gov/SLTC/etools/construction/electrical_incidents/burns.html...

When an electron leaves the lattice it leaves behind it a hole. So, the negative lectron leaves a positive hole. Because another electron will jump from further back in the lattice to fill that hole, you could say that the positive hols moves in the opposite direction to the electrons. Does...

A boost in aq direction would be to check out the Dick Smith catalogs. They have lots of great technical info on transistors and other components. http://www.dse.com.au/cgi-bin/dse.filereader?464da53301c6c530273fc0a87f9c06fd+EN/catalogs/CTG0000622...

These two cannons will both travel to the same spot (if we consider nil air resistance). However, the one fired at 50 degrees goes higher into the air than the one fired at 40 degrees and so will hang in the air a bit longer than the other one and thus will have a longer time in flight. Does...

OK, Eddy currents. Think of it this way. If you move a wire in a magnetic field, it induces a current in it. An eddy current is just that sort of thing BUT it is not in a wire but in a larger piece of metal and so the current has to circulate around inside the metal. So, inside a transformer...

BEST: New concepts, new maths, new ideas. WORST: New concepts, new maths, new ideas. It's a double-edged sword. But there must have been more good than bad for me to go and want to become a physics teacher :D
