Just solved Physics P6

[Bloodserpent]

Maaaaan!!! Oh crap got tht wrong :'( .... btw how many marks was tht q :S

3 marks

 

[SallyMatta]

Mine Was 0.16
When Temperature Was 80C Distance Was 11.9
If It Is 1C
Then We Will Do Cross Multiply
(11.9*1)/80
You Will Get An Answer Between 0.15~0.17
Just Do The Same Procedure Several Times (Around 3) With Different Readings From The Table
And Get The Mean
And It Was 0.16
I Aint Sure Btw
But Howcome Its 0.1??
Even If You Tried To Measure It By The Ruler
Its More Than 1mm/0.1cm
!!!!!

No if u do it properly by the ruler u'd get 0.10 cm or at least that's what my friends and I got

 

[SAMA_AI]

3 marks

Ohh well might just a get a mark for writting somethig

 

[SAMA_AI]

Hahahahaha oh u guys just leave it everyone got diff answers soo forget it whtever hapens hapens

 

[SallyMatta]

Guys what was the difficulty in the experiment and its solution i think i messed up in that question :/

 

[SallyMatta]

hey what about the question 1 that asked about protractor what was the answer

I put 3 i think any number above 2 is fine

well Idk 0.09cm made sense to me since 1 div on a cm ruler was little bit longer than 1 div on the thermometer that's why at 90*C you'd get about 7.9cm
I don't really remember how I solved that question.. I didn't sleep yesterday night :|
You can download s12_62 paper it has a thermometer of the same size xD

Shouldn't we take distance readings to nearest whole number ?
because the temp readings were to nearest whole number

He Said As Accurate As Possible
And The Question Had 3 Marks
And Noway You Get 0.1 or At Least -.-
Tell Me Your Working Please

 

[Bloodserpent]

I put 3 i think any number above 2 is fine

you mean the angle a of AC? it was 19*

 

[SallyMatta]

3 what he said the numbers

aren't u talking about how many times does he need to get theta? or which question are u talking about

Maximum Temperature Was 80 And The Distance Was 11.9
What Is 7.9 ??
The Least Number I Wrote In The Table Was 10..

 

[SallyMatta]

Tell Me Your Working Please

i calculated the distance between 0 and 1 degrees C since they want the distance between every 1 degree i am not really sure but that's what i understood from the question

 

[Baher Al-3rene]

i calculated the distance between 0 and 1 degrees C since they want the distance between every 1 degree i am not really sure but that's what i understood from the question

Using A Ruler ??
i dont really know
but it has 3 marks -.-
there must be some calculations

 

[SallyMatta]

you mean the angle a of AC? it was 19*

yeah in this question i put 19.3 i was talking about how many times does he need to calculate theta i put 3 for this one

 

[ahmed soliman]

the protractor suggestion was "N0"
right?

 

[Bloodserpent]

Maximum Temperature Was 80 And The Distance Was 11.9
What Is 7.9 ??

I didn't say 7.9 for 80*C..
It was one of the reading I took for calculating average distance..

 

[Baher Al-3rene]

the protractor suggestion was "N0"
right?

it was yes
values are within the limits of experimental accuracy
19 and 20
they are almost same since you cant record up to 0.5 degree
maybe yours might be accepted

 

[Bloodserpent]

yeah in this question i put 19.3 i was talking about how many times does he need to calculate theta i put 3 for this one

I put 10 xD

It was Yes

Ah, I gave 61, it was really easy Alhumdulilah!
