Thank you for your reply. I'm still quite confused with the GCE A level. So do i have to register both AS and A2 level (pay two exam register fee) in order to get the A level certificate? Or do i just register for A level (pay 1 exam register fee) and then I can automatically sit for both AS...

I am an American international school student , next year I'm going to take AP exams 2009 (Physics, Math, and English), and I also want to try out the GCE A level, 2009. I am confused by the AS and A2 exams, if I want to get the A level qualification, do I need to take both exams? Also, there...

Perfect! Thanks!

okay Thanks

So my length is probably about right. What confuses me is how to get the angle... I think it may have something to do with optics on mirrors... I know the angle should be 15 degrees or about that because I measured it from a to scale diagram, but I need to actually find it...

Homework Statement I'ts part of a bigger problem, but this is all the info given. http://img238.imageshack.us/img238/7923/chartro3.jpg Homework Equations I'm doing an experimental error calculation, and that equation wouldn't relevant, but that's the only one I got. The Attempt...

[Urgent] What is the angle of the the mirror? Homework Statement There is an intriguing aspect to Vermerr's "The Music" painting. If you notice, in the mirror there is a reflection of the woman and above that there is a reflection of what appears to be the feet of an easel. Upon closer...

okay thanks :)

hmm... That's odd I didn't use any instruments, I'm not really understanding what they are asking for though. Do they mean the error of the VALUE of the acceleration I calculated? Or do they mean the error of the acceleration in the experiment itself? Well, if I'm not given the actual value...

Homework Statement The problem let's us graph and give values for s(m) (distance) t(s) time and delta t (s) velocity. After plotting my second graph (including error bars) I used it to get the slope and the acceleration. But then it asks to determine the experimental error. Is there any...

I won't be wrong if I use simple algebra to get it instead right? Cause I don't have the angle...

Okay! I'll try it after I get some good night sleep! Thanks!

grrr... My trouble with this looonnngg question isn't over: I've determined all the errors, but there here comes the stupid part. What is the acceleration of this object? Show how you determine it, and THEN the experimental error for the acceleration? I'm not so sure how to do it, I thought I...

I cracked how to graph it, and yeah they wanted the length of the room which got me stuck. They say from the magnification i calulated earily and assuming the camera used a lens of focal length f with the image projected on the back wall of the room (and the object is on the far wall) and from...

Thanks, I figured it the other way around... it all makes sense, or why would we be give delta t(s) ? It's just I thought that they wouldn't ask a question that was dead obvious hehe Well, you confrimed my theory right! ;) I'll just explain before it get confusing: for the things I'm studying...
