Hope you are all up for it

Thats right btw

Kenshi

The principle of Conservation of Momentum states that in a system of colliding bodies the sum of the momentum before any collision is equal to the momentum after the collision provided that no external forces act upon the bodies

i thought u didnt need to know the proofs for formulae

CrimE

v= u + at => v^2= (u+at)^2

=>v^2= u^2+ 2uat + (at)^2
= u^2+ 2uat + a^2t^2
= u^2 + 2a[ut + 1/2at^2]

=>v^2= u^2 +2as

That was hard work typing

Q. Define Electronegativity (Chemistry)

crime u are really clever!

CrimE

lol thanks but im not really :cool:

Yep but you forgot to ask a question.

Funkstard

Are there going to be any non-chemistry ones here?


Weeeeeeeeeeeeee

CrimE

lol theres just so many questions you can get out of chemistry, but ill do my best to ask different subjects now

Ok just to kick start it again:

You need to know some of the proofs for Higher Level. There's not very many though, they took the majority of them off when they changed the syllabus.

Physics.

If you go to http://www.education.ie you can download the Physics syllabus, on page 56 of which there's a list of all the formula you need to know. The ones you need to be able to derive are marked.

Shrimp

Migrating within a country (e.g. from Dublin to Cork)?

yeah, next question?

ok i need urgent help in this maths question!! Its paper two 2000 question 6a
A bank givese each of its customers a four digit personal identification number which is formed from the digits 0 - 9 inclusive. Examples 2475,0865 and 3422

(i) how many different personal identification numbers can the bank use?

(ii) If the bank decided not to use personal id numbers that begin with 0 how many differnet numbers can it use??

Ive tried examination.ie they only give markin scheme till 2001!so im really stuck! I have a feeling the back of the exam papers are wrong and if they are right please tell me someone the methodology!!? Here is the anwser I am getting
(i) 5040
(ii) 4536

Please help thanks !

We haven't covered that topic/chapter in school yet however I think I might be able to help you but remember Im only trying to help
So here goes part i) You have a 4 digit pin in which each digit can range from 0-9(thats 10 digits)

Just look at this First digit 0-9= 10 possible [part ii) 1-9= 9 possible] Second digit 0-9= 10 possible
Third digit 0-9= 10 possible
Fourth digit 0-9= 10 possible
So its 10x10x10x10(or 10^4)= 10000
And that is the answer in the back of the exam papers

For part ii) the first digit has a range of 1-9 so thats 9 digits(see part in bold above)
So its 9x10x10x10= 9000
And thats the same as the answer in the back of the exam papers

I'm sorry if this has made you more than before and I know that I would never make a teacher but I hope this helps nonetheless. I dont think the above is the correct/best methodology and it probably only makes it harder than it actually is, again I'm only trying to help

(i) how many different personal identification numbers can the bank use?

(ii) If the bank decided not to use personal id numbers that begin with 0 how many differnet numbers can it use??


i) 10 x 10 x 10 x 10 = 10000

You can use the numbers more than once, so there's 10 possibilities for each number.

ii)9 x 10 x 10 x 10 = 9000

The first number only has 9 possibilites, since you can't use 0. However, for the subsequent digits you can use 0, so there's 10 possibilities

ok here's a new question...
