General paper discussion

[Saad Mughal]

I saved the answers in my calculator Ask any question you are concerned about
Will post p22 answers in a bit too

Can you tell me all the answers with the questions somehow?

 

[Kamihus]

has anyone done wid their maths paper2??

Yes, but no discussion till 24 hours after paper

I don't know whether its correct. There VHF radio waves.

I wrote it in brackets. It should be correct though...it's a broader term. What's u write in the second part. I wrote that they won't be deflected by any object since the waves travel in space & can therefore transmit signals in a short period of time

I just wrote they were quick,nothing else

Well, the actual reasoning was that they have just enough frequency to penetrate through things and high enough wave length to go through the atmosphere unchanged.
I wrote that they are not deflected by things and can be used to transmit signals globally, easily and quickly.

Do i look like a British Council agent?

Aap baat hee aesi krty ho.

 

[Aly Emran]

Umm. How am I supposed to know all this?

and i dont know which one of mine is right or wrong :S

 

[Snowysangel]

Haha and the mcq question about the broken filament. Did the current increase and the voltage drop down?

 

[Saad Mughal]

Haha and the mcq question about the broken filament. Did the current increase and the voltage drop down?

It was decrease decrease.

 

[Snowysangel]

It was decrease decrease.

Why would the current decrease? Won't it be short-circuited through the voltmeter?

It won't pass through when the lamp is broken. So, decrease.

54 and 18 were answers to a same question
133.3
65
28.1
50.4 Power and 6.72 kWh probably (got that kWh wrong so not sure)

The kWh was 0.00672.

 

[Kamihus]

The kWh was 0.00672.

Was the power in Watts? If thats the case then its obviously correct

 

[Snowysangel]

But the current wont pass through the bulb. It'll take the easier route which was through the voltmeter. Since the second bulb burst, the total resistance of the circuit decreased hence increasing the current...that was my reasoning

Yes, in watts.

I wrote increase decrease. But it was decrease decrease.

Was that question given as an option? I don't remember any question on power :-/ do u remember the wurstion for 54 & 18 btw?

 

[Kamihus]

Yes, in watts.

Thanks, i'll edit it.
