Physics p61

[aneeqa]

the difference was so little tho so thats why i said its within the experimental accuracy, i dunno

ur ryt dont wry

 

[aneeqa]

That question was for 2 marks!!!!! I dont get why...
I put 1.5

Yea it will be accepted



I got 1.53....and I think there will be like a margin of like 0.2 so I think it will be accepted

u had to hv 2 significant figures . if u wrote more than tht u get wrong

 

[Omar Hosny]

I did mass of the block 70 g but actually I saw a question like that in the past papers said that it was 1 N so 10 g is the most correct
to check that center of mass on 90..Measure Diameter of radius place it in between 90+D and 90-D...I wrote on the 2nd page REPEAT and the other question I wrote within limits of experimental ERRORS not accuracy will it be wrong ???
The problem can be Zero Error or Adjusting the pivot or maybe Air Current because it will push the mass

 

[ThatReallyReallyWeirdDude]

2 significant figures. answer was 1.5 ohms

I got exactly 1.5 too But I wrote 1.50 :|

 

[EpicLol]

I NEED HELP URGENTLY....FOR THE GRAPH I WROTE V/V Y-AXIS I/A X AXIS BUT I PUT THE SCALE OF THE DISTANCE INSTEAD OF VOLTAGE AND SO THE PLOTTING AND LINE DRAWN WERE WRONG AND I GOT A NEGATIVE GRADIENT !! HOW MANY MARKS WILL I LOSE ?

about 6-8 marks but if there is ecf then about 4 marks....dont worry

 

[EpicLol]

1.53 for the previous question (the gradient)

If u put mass as 70g then I think its wrong....coz u need to put in newtons coz its mass not weight....I put 0.5N which is like 50g....

Mass is in kg or g etc.... but not newtons and it did say mass

 

[eshal khan]

so 7.9 isnt acceptable??? because it wasnt 8 cm 100%

well they have ranges i guess so ur value might be correct i got exact 8 and 6 :S

 

[eshal khan]

Just remember guys, 1 mark in paper 6 is only 0.5%!

but when it comes tto loosing a lot of 1 mark questions so it makes a difference iam not talking about myself but in general

Guys for the last page 4 precautions i wrote:
1)the test tube wasn't vertical so some air escaped.
2)finger was alsi immersed so the volume will not be accurate.

1)air bubbles in the test tube.
2)measuring cylinder might not be dry.
wbu?

I wrote about the finger an parallax erreor for first one.
And for the second that the test tube wasnt filled completely and i think surface area of measuring cylinder different!
Think its coreect?

hahahahaha I wrote that the test tube isn't vertical in that Vw cuz I didn't know what to write else

Look you may consider me gay but I LOVE YOU I wrote that exact;y ;et's hope it's right

parallax is wrong bro, he said assume that he measured everything accurately as much as i remember

1) water lost when emptying water from testtube
20 finger one

1) the tube isnt all filled
2) water lost while pouring

I wanted to write "the tube isnt filled" but then they said the student doesn't make any mistake so I wrote abt the bubbles in the test tube. Do u think it makes sense?

 

[Abu mota]

i think it makes sense only in the first one but the second one, in my opinion, doesnt.

Also as for mass of ruler, we could do a preliminary estimation
Ruler would be 100cm long, perhaps 4cm wide and prolly 0.5cm thick
This would give vol. of 200cm3
Density of wood tends to be ~0.5 (depending on type, anything between 0.3 to 1.2, but the ones more than 0.7 are less common)
So the mass = dxv=0.5*200=100g, sounds about right P:
I wrote 250g cause I'm stupid like that.

I also wrote 250g !!

CAN ANY SAY ABT DA DISTANCE BETWEEN LAMP AND THERMOMETER ........WT DID U GUYS WROTE ON DA TABLE AND WT IZ DA MARK OF DAT TABLE
