Physics O levels complete discussion

Try this, this one's for GCSE o level.

thanks that's very help full

what do u suggest that how many papaers should we do for an a*?????

what do u suggest that how many papaers should we do for an a*?????

at least 10 year past papers for mcq's. and 2-3 year for theory is enough .

 

[sifat azeem]

thnks!!!!!

 

[daredevil]

can u explain this question... June 2005 paper 2 question 5a)
compasses are always confusing me. why is compass C pointing to the right? are we supposed to consider the poles of the solenoid or the magnets inside??

magnets inside. compasses direction moves from North to South.

 

[daredevil]

magnets inside. compasses direction moves from North to South.

ohh.... so first we'll determine the poles of the solenoid then the magnet and then we'll direct the compasses according to the magnetic poles?? uffff....!!!

 

[Khadija.95]

Ummm, in the formula of heat capacity and latent heat of fusion, is mass to be taken in kg?
And how does the size of the bore affect the thermometer's sensitivity?

most distressing science subject

yup its in kg.
wider bore means more sensitive
longer thermometer means less sensitive (but more range) [worst topic of O levels Physics] :/

HEY. Does anyone have notes on Nuclear physics?

 

[daredevil]

HEY. Does anyone have notes on Nuclear physics?

ummm.... i have them on pages but i have no way of uploading them here. sorry :| if u have Explaining Physics by Stephen Pople or Physics For You by Keith Johnson then do it from there. its really well explained. Good Luck
or if u have any single quesiton to ask then shoot i'm sure we all will help

 

[Salar2011]

Can anyone help me in this
Describe the use of a ripple tank to show reflection at plane surface and refraction due to change of speed

 

[Translucent231]

yup its in kg.
wider bore means more sensitive
longer thermometer means less sensitive (but more range) [worst topic of O levels Physics] :/

are you sure wider bore means more sensitive ? doesn't it reduce the sensitivity because the expansion will be less visible ?

 

[daredevil]

ohh. sorry about that!! :/ i 'm reaaly sorry every1! thinner bore means more sensitivity bcuz sensitivity is inversely proportional to bore size. thanks for correcting me here

ohh.... so first we'll determine the poles of the solenoid then the magnet and then we'll direct the compasses according to the magnetic poles?? uffff....!!!

first, using the right hand grip rule determine the north pole and then mark poles on both the magnets.
the magnetic feild i.e the compass arrows will move from North to South.
hope you get the point.

 

[AliMahad]

Is there a zip folder that contains a pack of several physics papers and their mark schemes? Because one by one is gonna take me lots of time :/

Well does anyone know the proper difference between potential difference and E.M.F .

From what i know emf the energy required to move a charge around the circuit , or any two points . while potential difference , is the difference in potential or energy between two points .

The easiest way to differentiate is, that Potential difference is the force needed to move a bunch of charges while EMF is the force to move a single charge.

I know the definition is childish but works well!

uuuuhhhmm.... your defenation of potential difference doesn't make sense.and i think its wrong ....... :O
