### #87243 Results Thread

Posted by gsmushet1 on 10 August 2006 - 01:12 PM in Exam Results 2006

H Mathematics, English, Computing, Geography - A

H Physics - B

2. Did you meet your expectations: Well i expected an A in physics and a B/C in English, so i both surpassed and didn't meet my expectations lol.

3. If not will you appeal? Yeah i think i'll appeal for physics to get the straight As

4. What are you plans now? Have an unconditional offer to study aeronautical engineering at Glasgow uni, that starts in sept 2007, until then i'll work so uni is easier financially.

5. How do you plan on celebrating? Already have, lol went out with friends to a few bars round town and had a few drinks lol.

### #79894 HElp day before exam!

ok. How the hell do you apply the descriminant (B^2 - 4ac) to an equation like this:

x^2 + (k-2x)^2 - 3x - 4 = 0

with intentions of finding the value of k.

The question says that y+2x=k is tangent to circle x^2 + y^2 -3x - 4 = 0. And to find the value of k (7 marks) .

In the anwswer booklet it says "x^2 + (k-2x)^2 - 3x - 4 = 0 apply to descriminant"

HELP exam is tomorrow:|

### #79258 How It Go?

Posted by gsmushet1 on 17 May 2006 - 05:39 PM in Physics

Can somebody please send me the paper. Pretty please. PLEASE!!

I don't have time to sit down and scan every page of the exam booklet, but I've taken some photos with my digital camera so hopefully you can make out what it says. Some of it isn't very clear, but it's the best I can do.. :/

Check your PM inbox.

Would you be most kind to send me them also?

### #76439 Optimization Help!

Posted by gsmushet1 on 28 April 2006 - 08:02 PM in Mathematics

I was wondering if anyone could give me some help on this subject. I am really good with maths and find it easy to follow set procedures etc when it comes to getting answers to question. However, when it comes to optimization with differentiation, i seem to lack the abstract thought needed for it! Maybe i'm over dramatising it with the word "abstract" but when i read through examples of things like finding the dimensions of 400m of fencing that willl provice the largest area in an open space, i understand what is happening at each stage...but i couldn't imagine myself thinking in such ways during an exam.

On such example gives you a cylinder and tells you that it is being designed to hold 400 litres and asks you to find the dimensions of the radius and height that would give you that volume with but using the smallest surface area. The processes that the example go through are very weird...making up your own formulae to suit the question based on various other types of equations and eventually differentiating one of the terms to find the stationary points and then find the max/min and use that to determine the smallest surface area etc.

I'm guess that there must be some sort of procedure to answering such a question. Or at least some guidelines or things you should aim for within your working to be able to answer. So can anyone tell me how to go about thinking about a question like this?

Thanks!!

### #75980 Photoelectric Emission - Help?

Posted by gsmushet1 on 23 April 2006 - 10:13 PM in Physics

I'm really confused about how it works. I don't suppose anyone has time for a little explanation?

p.s. Do you guys get paid for helping us?

Well the electrons that orbit an nuclues do so at different heights from the nucleus known as "energy levels". Each level has a particular energy assigned to it. When a photon that has energy equal to the energy difference of two levels becomes incident on the atom then an electron on that level is given enough energy to move up another energy level(into excited state). If an electron in the excited state is given even more energy, then it is given enough energy to be released from the atom and is then known as a "photoelectron" which has just undergone "photoelectric emission".

I don't think they get paid:S..i'm just a random guy, not involved with the site in anyway.
