IGCSE Physics Paper 1 Variant 1

[AGOGO]

Yeah that is correct. Too bad I put 84!!!

But overall it was a great paper.

Same Mistake

Al7amdillah! did u have any doubts on other questions?

 

[AGOGO]

What About CAKE QUESTION anybody did it ?

What About CAKE QUESTION anybody did it ?

Dude.. that ws in maths!

 

[AGOGO]

Dude.. that ws in maths!

Oh.....sorry i got confused coz Today MATH P4 & PHYSICS 1

Al7amdillah! did u have any doubts on other questions?

Of course. But I got them cleared by reading this page.

 

[Reem2195]

What about the difference you'd make so the boat is less likely to hear the sound?

 

[irfhan]

which one??

-Liquid expanding
-Its 84 because pressure of gas =atmospheric pressure + difference in height

YESS

 

[TheBaller23]

how is it constant resistor?? if its a constant resistor then the resistance would be constant, duh!! and by referring to the graph the voltage increased as the current increased, so it's a capacitor..

 

[hamada]

what aboute the question of the boat and the sound wave

 

[Reem2195]

how is it constant resistor?? if its a constant resistor then the resistance would be constant, duh!! and by referring to the graph the voltage increased as the current increased, so it's a capacitor..

It was probably a constant resistor- I'm not sure though.
This link might help. http://www.gcse.com/IV_wire.htm

 

[Weirdal95]

76+(-8) ahaha .. not plus 8.
it is a constant resistor dude

 

[Weirdal95]

the boat one was , make gap bigger and diffraction

 

[hamada]

are you sure

 

[Weirdal95]

Yes 100%.

 

[Reem2195]

the boat one was , make gap bigger and diffraction

you're sure?

 

[Yousif Mukkhtar]

That is right because bigger gaps reduces diffraction.

 

[Reem2195]

yay!

 

[Jspake]

The answer for the boat qn was to make the gap smaller.. this will prevent the waves from reaching the boat

 

[Manobilly]

Guys.. what was the answer to the potential divider question??

A ! It would drop from 12 to 0!
