physics paper 1,2 ........can we discuus da papper nw?

[Mayedah]

I thought of water bathing it, but then I thought that would be hazardous. So I wrote that keep the wire above a boiling liquid (that boils at 25-30 *C) because it would give constant temperature. I guess I thought TOO hard on this. lmoa. Now, i feel the first one would be right

Hey wht was the answer to the filament lamp and resistor one ?

Somebody told me they notify the 'distinctive' candidates on January of the following year. I'm really not sure tho.

no i think they do it in december the same yr cuz someone i know got distinction so i know. at least i think so.... only an achiever can tell the ryt thing. though i don't remember if it was dec or nov..

For all the people out there, answers for the most confused questions are :
For Table tennis ball, Velocity increased, acceleration decreased
For the coin, P increased, resultant decreased
For the moments (in "sea-saw" :| ) , 5N
For pressure, 2p/3
For fuse, I don't remember (actually the question was so easy i didn't look back at it again ^^ )
For the center of mass of the shapes, it was the one with with broadest base (C).
So there. Anymore?

yayyy..... all of mine are correct *dances around*
kaun sa fuse wala?? elaborate so that i can remember it

Oh man I pointed X upwards, becox I thought that must be the force currently acting on it which pushed it upwards ....had it been before or after crest I would have surely got it right..

dont worry! i did the same thing too!

 

[daredevil]

hey! can anybody tell me how the temperature of the wire wsa kept constant?

i don't remmeber wht i wrote but i think i wrote by using a fan b/c the current passing through the wire will heat it up so if we cool it using a fan the temperature can be kept constant also check the temperature at regular intervals and whenever it increases switch on the fan. i know its waayyyyy to simple but sometimes that's what they require. hope i'm ryt.

paper 4 is out of 30 marks!

ohhh....yeah 25 nt 35........

Hey wht was the answer to the filament lamp and resistor one ?

which one?

 

[twelveoclock]

How were the magnetic fields in the iron core supposed to be drawn? The question carried 3 marks. :O

 

[Mayedah]

which one?

which one?

The one in which three graphs were given and they said hich graph represents filament lamp and which resistor ?

 

[twelveoclock]

Think it was the straight one for resistor. And the one shaped like an 'S' for the filament.

Idnt remember a S shape

 

[twelveoclock]

Idnt remember a S shape

I don't know how to explain it...it starts straight but aik point par it curves. Like this:

For resistor it was like this ' / ' and for filament it was a curve of decreasing gradient.

K thanx both

hey for temperature constant of wire i wrote to immerse in water bath at cnst temp....wat do u guys thnk?

 

[asd]

It was like this but starting at (o,o)

That's correct, i guess, i thought of writing the same thing, but didn't write it gosh!

Yeah i got this mcq wrong i confused it with the first graph which represented thermistor :/
