How was physics paper 33

[angelicsuccubus]

lets think about it this way... if metres/grams is plotted against 1/grams... do they have a positive relationship? Take any values you want..
Edit: Remember that our values were in 0.00s and the difference between h.-h increased

But guys, What were the two questions about?

 

[thunderingthunder]

okay I need you to answer every question Im about to type:

1) Which string did you hang the masses on? Short one or long one?
2)What was your h. (the fixed one) ?
3)Were your values for (h.-h)/m increasing as (1/m) decreased or were they both increasing or decreasing?
4)Did you plot (1/m) on the x axis?
5)Did your h value decrease by 0.02m or 0.03m every time you added a weight?

I DON'T remember anything:S

 

[thunderingthunder]

yeh mine either.. my y intercept was 0.0006 and my gradient was -0.15

my gradient was +0.11:S

 

[thunderingthunder]

But guys, What were the two questions about?

Are you going to appear for another variant?

 

[angelicsuccubus]

Are you going to appear for another variant?

no ... can you do that?!

and thats thing with all of you people who got positive gradients, you dont remember what happened in the paper!

 

[thunderingthunder]

no ... can you do that?!

No..what i actually meant was that is she/he appearing for variant 34

 

[thunderingthunder]

and thats thing with all of you people who got positive gradients, you dont remember what happened in the paper!

What's done is done..I got my Bio P42 next to worry about so right now i don't remember anything else

yeah right

 

[Knight]

i also got a -ve gradient...........and it should be negative.

 

[Saad Sarfraz]

gradient 0.0685
y intercept 0.836
k1 = 740, k2 = 550 (i took it in meters)
temp change in cup =3
temp change in bowl =5
Hope this helps u or scares the shit out of u
Like n Reply if ur getting same or something

Gradient 0.05
Y intercept 0.47
Temp change in cup 5
Temp change in bowl 9

My temperature change for both was approximately the same too, at around 4 degrees. Is that alright?

 

[Saad Sarfraz]

yeah right

Guys i asked my sir he said for those who got a negative gradient only 1 mark will be deducted. People who mostly got the negative gradient didn't measure the First height accuratelyy..this is the truth !!

no, you should get different temperature changes as the surface area for cup and bowl was different lol.....

no, i measured the initial height correctly(usng the set squares) n still got a -ve gradient.

Guyz, this was the apparatus set up, did u do this way, as this one was correct. https://www.dropbox.com/lightbox/home/Photos/Sample Album?select=Untitled.jpg

I measure initial h correctly with set squares

 

[Knight]

I measure initial h correctly with set squares

that's exactly what i did

 

[mujtabashahnawaz]

that's exactly what i did

and by this method i got a negative gradient
