hey r we suppose 2 know the quantity of charge for static electricity ive seeen it in notes somwhere but i really dont understand it .. and its not in ur notes ???
never heard of that in my life

i think he means repulsion of  like charges and attraction of opposite charges ..this is mentioned in the static electricity chapter mate

idk i was just guessin  :-X

i think "quantity of charge" means "amount of charge" Coulombs

Q = It

is tht wat u mean Soona ??

V = IR

Voltage = Current X Resistance

GENERAL PHYSICS
[/color]\
not much i can do bout this but anway  ill tell you what you need to okno

DENSITY - MASS/VOL Kg/m3 or g/cm3

Mass of regular solid : PLace onto a balance / Volume ( cube or cuboid ) Lxbxh   /
NOTE : if u are given spring balance then the weight should be found first and then Divide by 10 !! to find mass

You have to know how to find the volume of irregerual solids ( the volume experimetn or displacement experiments )

You have to know difference between SCALAR QUANTITIES ADN VECTOR QUANTITIES
SCALAR HAS ONLY SIZE ex. temperature , mass , time
VECTOR HAS SIZE ( MAGNITUDE ) AND DIRECTION  ex. velocity  weight , acceleration , force

acclration = chage in velocity / time   .. unit : m/s^2

Distance time graphs : very rare  but you have to know what the gradients mean !!!

http://www.gcse.com/fm/dtg.htm this is the perfect site for this . JUST CLICK ON NEXT PAGE ( AWSOME  :-X ::) ;D)

Speed time graphs

http://www.gcse.com/fm/stg.htm

you shuld know how the ticekr timer works

ll complat 2mrw goodnight
kimo thanz a lot but hey de ticeker timer i dunt thnk its dere well if yes can u help wid dat we were never taught thanz

Also,

V I = P

Voltage x Current = Power

i finished THERMAL / ATOMIC / GERNAL PHYSC and i jut haevto post some pictures of ELECTRICTY and then im done ! by tonight hopefully


THEN I WILL HAVE WAVE LIGTH ADN SOUND AND ILL TRY TO COMPLTE THAT IF I CAN  .. I APOLOGISE IF I CANT 
i did my best ( maybe not :P )  !

A simpler way to think of convection would be that cold air is heavier (more dense), so they have to be at the bottom, and hot air is lighter (less dense). Imagine if you have a heater placed on the floor, sadly your feet will always feel cold as the hot air rises :D

This way of thinking is particularly useful when you are dealing with MCQ questions on convection.

Not sure if anybody has talked about this, but sound waves require a medium to travel through! This is a classic question which appears in MCQ almost every year ...
