i need to know what exactly the things which i need to study

 

[Moi]

Please Help !! I still don't get how the Generator and the Motor work !! And the whole commutator and slip / split brushes thingy !! PLZ HELP, Can someone explain it to me ??

u just write the layers will become taller because the amplitude will change

 

[mr0fisher]

the mark scheme sometimes confuses me

i knw but the ms says that ignore that n compressions are narrow.. :S y is that so?

i need to know what exactly the things which i need to study

the formulas
speed,acceleration etc
waves electricity
radioactivity
pressure
moment
i think thats all

when the sound become louder the amplitude rises u must learn this

when the sound become louder the amplitude rises u must learn this

but for the ques em askin the markingscheme states that IGNORE 'AMPLITUDE GREATER'

Guys when do we use left and right hand rules?
