Thanks so much to everyone. I finally understand! Once again, thanks everyone. Cheers

Thanks PrettyVacant, But what does it mean "scalars are the magnitude of the corresponding vectors"?

Can someone just explain to me what n2 and n1 are? Thanks.

Just began some work in class today about the following: vector scalar displacement scalars are the magnitude of the corresponding vectors displacement/time graphsMy teacher ain't very good, and I kinda struggled to understand it all. I read my textbook twice (Physics 1) but still don't fully...

Anyone know where I can get a crack/serial code for Flight Simulator X Delux Edition from? Cheers

madelyn and everyone else Iv' been thinking of doing the same thing as well. Going overseas for bout 6 month between HSC and UNI. Europe, Canada, and South America. I love travelling. Travelled all over Asia and South pacific with family. Good luck everyone and hope you enjoy ur travels. Might...

sounds great matt_Aussie, but the internet and fibre optics is not an option available to choose for this assignment.

I have basically the same assignment, and I can find heaps of info for how GPS works, what it consists of, etc, but nothing on how it has developed with the advancement of technology, how it uses properties such as reflection, refraction, etc. Where can I get some info for principles of...

Quote: Moco - "I've got this in class physics assessment dued this thursday on 8.2,5,2nd col,point1 and was wondering if anyone has already done this in class.I've chosen GPS and found heaps of info. but the question is so broad! i wanted to know which main bits should i focus on. like how it...

@ my school, we are covering this dot-point with an actual assessment task (research assignment). I have elected to do GPS, and like you nelses, even with hours of research, I ended up with nothing myself. Nothing relevant to do with the "application of physics related to waves". My assisnment...

Hey everyone thanks for your help. However, my teacher went through this homework in class today and it appears that some of it is wrong.:confused: My teacher says the formula to complete the area column is 4πr². This doesn't seem right to me. Also, the time is actually the...

Cool. Thankyou so much ianc and alcalder. I really appreciate it, and I now understand how it all works. However, one last thing. I forgot to mention part 2 of the question: Draw a graph of I(intensity) against the inverse of distance squared. What I don't understand is that the inverse of...

Hey guys, just got some h/w yesterday about "Inverse of distance squared". We have to complete a table which consists of four columns: Column 1 - distance (metres); 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, and 0.9 Column 2 - time (seconds); (blank to fill in) Column 3 - Total area (metres...
