I know how daunting it can be to think of your first day at college and where your studies will take you. You know what subjects you want to take but you still aren't certain. Or, you are 100% sure what subjects you wish to take but are afraid of regreting it later.

Either way, here is a thread dedicated to the AS students to-be. I know how disasterous it was having to mingle with different people and not be able to work on my own. I have completed my first year and in 8 days will begin my second year at college. Hey Presto! That was fast!

This is a thread for all you AS Students to-be to discuss any issues from: 'what are the most recommended subjects to be an astronaut?' to
'what is the unit for frequency?'

Don't feel that your life has become a nightmare since starting college - infact, this is your chance to shine!

All you have to remember is: do your best at college, dont waste time and leave the rest in God's Hands.

If you fail in your mocks, don't give up! I didn't and I'm still breathing.

So, feel free to ask any questions regarding life at college or questions regarding your course. I will mainly beable to help with:

Biology
Chemistry
Physics
Maths >> I've taken this on board so we'll do AS together

I am sure other br and sisters will help with the remaining subjects!

will you be taking Psychology - AQA Specification A?

if so, I strongly recommend the past papers and mark-schemes which you can download from here:

salam,

actually, it doesn't matter which specification, as long as it's AQA, you should be able to find past-papers for any subject for free on that website (http://www.aqa.org.uk)

for example, if you find out that you are taking Psychology Specification B, instead of A, then you would use this link instead:

http://www.aqa.org.uk/qual/gceasa/psyb_assess.html

I think the use of past-papers and mark-schemes is vital if you'd like to get an A in this subject, or any other 'written' subject for that matter.

Unfortunately, Edexcel do not give out their past-papers for free - you have to buy from them :|

I am so happy, today I recieved my home schooling folder for mathematics. I started the first exercise in the car and it seems okay. They seem to include a numer of Physics equations which is nice! Talking of Physics, I also picked my A2 Physics book (it was ordered). It is just as thick as the AS book. I can't wait to do some reading!

Can't wait to begin college!

Good luck to all.

  1. Maths (Mechanical)
  2. English Literature

Firstly, I am glad you find that this thread will be of use to you.InshAllah.

Secondly, you were not freeposting. Freeposting is when you post to the opposite and add things such as 'lol' to your posts. Basically, freeposting is fitnah and you were not doing that. I believe, you meant to say: offtopic. In which case, you were not offtopic either.
Thirdly,it is okay to mention what subjects you are studying as others who will read your post may need help with the same subjects you are studying and may wish to ask you.
Almost there, you mentioned you were studying mechanical mathematics. What board are you taking?

Finally, what is socialogy? I have heard of it so many times but I have no idea what its about. Care to share some facts!

Wasalam

p.s: Weird combination of subject choices? I don't think so.

I think sociology is the study of society, and how the society plays a major role in influencing a person. Whereas psychology is more linked to the mind. That's why they're both kind of linked together. wa Allaahu a'lam.

You're right. Sociology is the study of people in groups and although it does take into consideration the study of individuals, it looks at the bigger picture and concentrates on groups of people, how they act the way they do etc.

I had my first sociology class today. :)

Yes, it was interesting. We are currently discussing the nature v. nuture argument. Today's lesson concentrated on feral children (children brought up by wild animals and subsequently adopt many of the behavioural patterns attributed to them; there was a documentary on Channel 4 called 'wild child' and you can check out www.feralchildren.com if you are interested)

In answer to your last question: people fascinate me. Why do some people act the way they do, what influences them, how do certain things affect them etc etc. I'm taking psychology and inshaAllah i want to go onto study psychology in depth at Uni, and as sociology is inter-connected i've decided to study it. Oh, and whoever says psychology/sociology are 'common sense' subjects are very wrong as it is based on research and evidence not just opinions. :giggling:

here is part of the Formulae-sheet for C2, from Edexcel's website..

you can see that the equation you mentioned in your question is part of the C2 specification:

I think what happened is that they used an equation from a C2 topic - as an example - in the C1 topic you mentioned: 'Evaluating formulae, simlpifying expressions and expanding brackets.'

09-07-2006, 10:30 PM
this is how I would evaluate the equation using the values given in the question, although somebody else might know a better way :


a = 3
r = 1/3
n = 4


S = ...


a ( 1 - r ^n )
__________

1 - r


substituting in the values given in the question:


3 [ 1 - (1/3)^4 ]
_____________

1 - (1/3)


simplify top and bottom:


3 [ 1 - (1/81) ]
____________

2/3


then expand brackets:


3 - (1/27)
________

2/3


multiply both top and bottom by 3:


9 - (1/9)
_______

2


simplify top:


80/9
____

2


finally, this simplifies to: S = 80/18 , which further simplifies to 40/9 .


please let me know if I can clarify any part of this answer.

salam,

Please see my comments after each step of the answer, given in bold.


a = 3
r = 1/3
n = 4


S = ...


a ( 1 - r ^n )
__________

1 - r



This is the equation given in the question, and you will be trying to find out what 'S' is (left-hand side of the equation), using the values of 'a' , 'r' , and 'n' given in the question, by substituting them into the right-hand side of the equation.


substituting in the values given in the question:


3 [ 1 - (1/3)^4 ]
_____________

1 - (1/3)



Here you simply put in the values of 'a' , 'r' and 'n' , as given in the question, into the right-hand side of the equation (you replace the letters with the numbers). This is because you are trying to find out what 'S' is equal to, and 'S' is equal to everything on the right-hand side of the original equation.


simplify top and bottom:


3 [ 1 - (1/81) ]
____________

2/3



To simplify the top of the fraction, 3 [ 1 - (1/3)^4 ] , you need to work out the (1/3)^4 part. To do this without using a calculator, you need to know that according to one of the 'rules of powers', (1/3)^4 is the same as putting both the top and bottom parts of the fraction to the power of 4, like this:


1^4
____

3^4


and since 1^4 is 1, and 3^4 is 81, this part becomes 1/81 .


To simplify the bottom part of the fraction, 1 - (1/3) , you need to know that '1' can be written as 3/3 , so that instead of working out 1 - (1/3) , you can work out (3/3) - (1/3) instead. (3/3) - (1/3) , is 2/3 , because when the bottom parts of two fractions are the same (which is 3 in this case), you can just subtract the top part of one fraction from the top part of the other fraction, whenever you want to subtract the one fraction from the other (it is one of the 'rules of fractions').


then expand brackets:


3 - (1/27)
________

2/3



To expand 3 [ 1 - (1/81) ] , you multiply what is on the 'outside' (3 in this case), with each term on the inside. So after expansion, this becomes 3 x 1 = 3 , and
3 x (1/81) = 3/81. But 3/81 can be written in a more 'simple' / 'smaller' form, because you can divide both the top and the bottom of this fraction by the same number, to get a more simple fraction which is equivalent to the original. Dividing the top '3' and the bottom '81' by 3 gives 1 and 27 respectively. Therefore, you can write 3/81 as 1/27, as both of these fractions are equivalent, but the latter is 'simpler'.



multiply both top and bottom by 3:


9 - (1/9)
_______

2



Here, you are multiplying top and bottom by 3 because you want to get rid of the fraction at the bottom (the 2/3) . Multiplying the bottom by 3 eliminates this fraction, making the 2/3 become just 2. To multiply the top, 3 - (1/27) , by 3, you need to carry out this expansion: 3 [ 3 - (1/27) ] . So again, you multiply the 3 which is 'outside', with each term inside: 3 x 3 = 9 , and 3 x 1/27 is 3/27. However, once again, 3/27 can be written in a simpler form, by dividing both the top and the bottom by the same number (3 in this case), so 3/27 becomes 1/9 instead.


simplify top:


80/9
____

2



To simplify 9 - (1/9) , you need to write the '9' as a fraction which will allow you to carry out the subtraction without using a calculator. To be able to do this, you need to make the bottom parts of each fraction the same. Looking at the (1/9) , you can see that the bottom part of this fraction is 9, so you should try to also write the '9' in a fraction-form with 9 at the bottom.

This is how you can do this -

think of 9 as:


9
_

1


Using the rule: you have to do to the top whatever you do to the bottom (and vice versa), you can multiply both the top and the bottom of this fraction by 9 , in order to convert it into:


81
__

9



now that you have the '9' written in this form (81/9), with 9 at the bottom of the fraction, you can work out the 9 - (1/9) part, by working out (81/9) - (1/9) instead. The bottom parts of these two fractions are the same, so you can just work out 81 - 1 (subtracting the top parts), to arrive at 80/9.


finally, this simplifies to: S = 80/18 , which further simplifies to 40/9 .


Dividing 80/9 by 2 gives 80/18, because when you divide a fraction by any number, you can simply multiply the bottom part of this fraction by that number (it's one of the 'rules of fractions'). 80/18 finally simplifies to 40/9, because you can divide both the top and the bottom parts of this fraction by 2, to arrive at the fraction, 40/9, which is equivalent to 80/18, but is simpler.


Please let me know if you have any questions about any parts of this post.

I was looking through an exam paper yesterday and today and I just could not get my head around the mark scheme answer. So, could someone answer the question please.

Q)The RAM of Iodine in the Periodic Table is 126.9 on the data sheet. Explain what this value represents.

(3 marks)

I read in the mark scheme it had something to do with radioactive deacy. But, I asked my teacher today and he said the answer is basically...emm..to do with Carbon. He only mentioned a few words so I can't see how that was only a 3 mark question. HIS answer had nothing to do with the mark scheme answer.

RAM = relative atomic mass (in comparison to carbon)

So 129.6 is the relative atomic mass of iodine relative to one twelvth of a carbon-12 atom

I think it's something on those lines :)

These are the two answers I would give:

1) Thin diameter of walls - made of only a single layer of epithelial cells - (so this reduces diffusion-distance).

2) Large surface-area - (so this increases rate of diffusion).


I'm sure there are other answers.

Keep revising sister, and do all that you have power over in this world. Then make lot's of dua' and put your trust in Allaah azawajal


..put your trust in Allah, certainly, Allah loves those who put their trust (in Him). (3:159)



This is the way of Allaah's messenger (peace be upon him.)


Sahih Bukhari Volume 4, Book 56, Number 747

Narrated Rabia bin Abi Abdur-Rahman:

I heard Anas bin Malik describing the Prophet saying, "He was of medium height amongst the people, neither tall nor short; he had a rosy color, neither absolutely white nor deep brown; his hair was neither completely curly nor quite lank. Divine Inspiration was revealed to him when he was forty years old. He stayed ten years in Mecca receiving the Divine Inspiration, and stayed in Medina for ten more years. When he expired, he had scarcely twenty white hairs in his head and beard." Rabi'a said, "I saw some of his hairs and it was red. When I asked about that, I was told that it turned red because of scent. "



Compare yourself to what you're going through, and what the Messenger of Allaah (peace be upon him) went through. And at the end of his life, he only had 20white hairs in total. Look at the seerah (life story) of Rasulullah (sal Allaahu alayhi waSalam) and you'll see how much hardships he faced, but he (peace be upon him) put his trust in Allaah, after doing all the worldly actions he had control over.


So follow that example insha'Allaahu ta'aala.

(3 marks)
salam,

this is how 'Relative Atomic Mass' (RAM) is defined in an A-Level Chemistry book:

"The Relative Atomic Mass of an element is defined as the mass of one atom of that element relative to 1/12th the mass of one atom of carbon-12."

(this is what sr. asma said above, and also probably what your teacher was talking about when you asked him.)


..the book then continues the definition to say:

"The Relative Atomic Mass is the average of the masses of the stable isotopes of the element, weighted to take into account the relative abundance of each isotope."


So this latter definition is what the mark-scheme is looking for, but the mark-scheme split up this definition into three parts, each part being worth a mark each. I have matched each part of the definition above with the corresponding marking point given in the mark-scheme (below), by using associated colours.


Mark-scheme answer:

- Weighted / Weighed / taking into account (relative) abundances / Intensity / percentages

- average / mean mass

- of (naturally occuring) isotopes / atoms of different masses


If you take these three marking points and combine them together (in the given order) to form one sentence, it can become: 'Weighted - average - of (naturally occuring) isotopes' - which says the same thing as the definition given above.

please let us know if you need help understanding any part of the definition, such as what an 'isotope' is, or what 'relative abundance' means.

salam,

below are the grade-boundaries used for the Edexcel Biology Units taken in January of this Year (2006). The grade-boundaries do vary from time to time - but only slightly if they do.


grades -



According to this, a grade E would require roughly around 40% of the marks.

salam,

The grade-boundaries used by AQA should be very similar to those used by Edexcel (ie. around 40% for grade E). The above list is from the back of a mark-scheme I have for Edexcel - but not AQA.

There may be something on AQA's website though (www.aqa.org.uk).

salam,

I found the AQA grade-boundaries on page 3 of this PDF file on their website:

http://www.aqa.org.uk/news/GRADE_BOUNDARIES.PDF

For grade E , their requirement is also around 40% for the Biology Units.

[MOUSE]Physics issue[/MOUSE]

This question is set as a revision question for homework. I have read it carefully and managed to pick out what I believe to be the important parts.

The question is about:
-a shower system
-the syetm can be operated with one/two 4kW heaters connected.

Q) explain why the water achieves a contant temp when the shower is operating.


A) Because, the mains will switch on which means the heater chamber will heat the water. If the coils become too hot then the heater chamber will switch off and water will cool down.

Is my answer right?

wasalam and jazakAllah.

ALSO: What is the formula for flow rate? It is to do with specific heat capacity - E=MCT

Assalamu alaikum Sister,

I cannot comment on whether your answer is right or wrong. I would say more information is required in the question for it to be the answer they are looking for, specifically about the the heating system and how it operates, which you did not give in the question. Or the context from which the question is taken from could mean your answer is the correct one.

Looking at the question on its own, I would simply say that the temperature of the water is constant because the 'flow rate' is constant when the shower is operating, and the power is constant (rate of energy transfer is constant). Therefore, as they are both constant, the temperature of the water stays constant.

Hope that helps :)
