How was your Physics???

[Iffat]

How as your Physics paper 2???

Mine was terrible

 

[ritesh isuri]

some questions was quite well but others!!!

 

[ritesh isuri]

can anybody tell me how much he/she got for the maximium temperature change when the piston was pushed and how he/she did it?

 

[Iffat]

Did u write paper 21 or 22? coz i wrote 21 and dont remembr seeing such a question

 

[ritesh isuri]

paper 22

can anybody tell me how much he/she got for the maximium temperature change when the piston was pushed and how he/she did it?

I got some thing like 2.74. You have to find it using the equation e=mc(temperature difference) and they havent given the mass so you will change the force you found earlier (which was 2300N or something) to kg and substitute it in the equation

I did Paper22 and some of them were good but others wasnt :/ But inshah allah I will get an A*

i had a doubt so i had used the equation e=c(temperature difference) and got 630 as answer thats why i was having a doubt because it was too much!!!

i will pray for u !!!

Me and my friend got 2.74 degreee celcius. The temperature difference is not that big. But hopefully you would have done the rest of the paper well

i will pray for u !!!

Thank you! I will pray for you too!

i too got 630

 

[aneeq247]

i got 630 too

 

[Nerdz]

i too got 630

But 630 is too bifpg for the temperature difference. Did you change the 2300N to mass and substituted it in the equation?

 

[ritesh isuri]

it was heat capacity that was given and not specific heat heat capacity!!! so i think that we should have used the equation q=c(deltafeta) and the 2300N was not the weight of the gas particles!!!

 

[aneeq247]

exactly, i used the formula Q=C/DeltaTheta. It doesnt matter how big or small it had to be, i just applied the formula and went with it.

do anybody know the speed that we we have to find in bungee jumping

 

[ritesh isuri]

how much did u get . i have forgotten my answer but if u tell me urs maybe i would remember if i got something like that

 

[ritesh isuri]

does anyone know the energy conversions which took place in the bungee jump?

 

[jatin]

i think i got 20m/s
