How was 9702 W15 paper 22?

[ahmedish]

I hope the other papers are easy so we get high adjusted marks hahahahahahahah

 

[ahmedish]

The question was is the power 48W, not about Terminal PD

it was a 48W, 12V lamp. It asked what happens to the current through it when switch 2 is closed in b)i)

 

[Huzaifa_12345]

it was 4V pd
then what happens to Vab ----> it increases
it doesnt matter how you got it

If true, perfect

Yes, correct. Originally asked why 48W aren't transformed in it too in part A.

Just a bit of doubt over the L1/L2 question with the current part and the ratio for power (1.4?)but I think its fine.

ratio is 1.4 yes. and yeah you have to talk about terminal pd and lost volts etc
there werent any hard definitions
I am losing 6-7 exactly I checked everything hope we get adjusted marks

What was ur last answer about density!!
Was it sth 5.5 * 10^11 thing??

Yeah!

I got 11:7, which is like 1.6

 

[The Sarcastic Retard]

I got 11:7, which is like 1.6

Mine was something like 1.43 : 1

 

[The Sarcastic Retard]

I got 11:7, which is like 1.6

Though my friend got 1.62 : 1

 

[The Sarcastic Retard]

Mine I1 was 0.16
Mine I2 was 0.24
0.24^2 * 350 = 20.16
0.16^2 * 550 = 14.08
so P in 350 / P in 550 = 20.16/14.08 = 1.43 : 1

 

[ahmedish]

Yeah!

i used pi r squared instead to get that and did it wrong

Mine I1 was 0.16
Mine I2 was 0.24
0.24^2 * 350 = 20.16
0.16^2 * 550 = 14.08
so P in 350 / P in 550 = 20.16/14.08 = 1.43 : 1

thats correct is 1,43 to 1

One more thing I left my answer as 63/44 and 1.43 will they gimme marks?

 

[ahmedish]

what do u mean? you wrote both in the dotted answer?

 

[The Sarcastic Retard]

what do u mean? you wrote both in the dotted answer?

Nope. 63/44 in that white space. And 1.43 in dotted space.

 

[The Sarcastic Retard]

What was resultant magnitude of velocity in Q1 ?

 

[The Sarcastic Retard]

How about graph?

 

[The Sarcastic Retard]

Waves???
D1A and D1B thingy what was that?

 

[The Sarcastic Retard]

Expected GT?
I guess it will lie around 40 - 43

 

[DarkEclipse]

Hell no. 40 max, 35 most probably.

Guys, what was your value of your resistance R in the first question?
