how much will lose , for second part will i b given e.c.f

1 mark max rest will fall in ecf

1 mark max rest will fall in ecf

ufff thnx
did somone diid last part . what was tthe current. i got 0.25. and Resistance of R i got 25

I don't think there was any need to convert. The areas of the pistons were in cm^2 and you could calculate the pressure in N/cm^2. Then multiply the 2 and get 166N

How did you guys do the part about the heat capacity? What values did you get?

 

[asadalam]

How did you guys do the part about the heat capacity? What values did you get?

0.504 g
114354 J or something like that

the mass of water i got 0.26 smthing, dont exactly remeber

 

[Lilly2318]

Anybody having English P2 tomorrow?

Mass was .504 kg and Energy was 114k something.

 

[Awesome12]

0.504 g
114354 J or something like that

0.504 g?
That is soo light

 

[Lilly2318]

Same.

We have to bend filament graph towards V towards end right? And difference b/w fixed resistor is fixed resistor has zero gradient?

i wrote it is a straight line as V is prportional To I

 

[Lilly2318]

i wrote it is a straight line as V is prportional To I

what was the use of resistor. I wrote so that a known value of current passes

 

[Lilly2318]

Everybodeh! :v

Hows prep?

yes you wrote the right unit
the ones who wrote pascals got it wrong

Why was resistor used? #SectB #Q3

 

[Abdul Hanan]

0.504 g?
That is soo light

0.504 kg not g

 

[Lilly2318]

My English is good. I am pretty scared about this as I did argumentative - so I am preparing a little. But mostly doing chem today

what abt resitor. i wrote so a knwn value of current passes

 

[Ram97]

Sec B Q.9 xperiment to chk if speed is constant

 

[asadalam]

0.504 g?
That is soo light

.-. i meant 0.504 Kg

Why was it accelerating while turning?

 

[Ram97]

Why was it accelerating while turning?

I wrote something related to Centripetal Force. Can't remember
