How was Physics 6PH08 Alternative to practical ?

We always have to consider 0 error..

What was your percentage uncertainty of the diamter??

What was your percentage uncertainty of the diamter??

0.01/25.9 into 100

 

[toxic]

The percentage uncertaini for a vernier caliper is 0.01 mm.

vernier calliper is .1mm

 

[Choco<3]

vernier calliper is .1mm

Oops..sorry ..0.1mm right.

 

[toxic]

0.01/25.9 into 100

generally we do 1/2(range) divided by the mean multiplied by 100

A

generally we do 1/2(range) divided by the mean multiplied by 100

1/2 (max-min) divided by range into 100 ..but there wsnt any Max or min..dor diameter..it was the same..25.9

Yeaah maybe they tried to trick us!

Do u think u r right?

No wonder why I hate them!

wht was the total mark for Question 1 ??

 

[Outofideaz]

Question 1 part (a) was 1, the measurement of volume was 2 I think, and percentage uncertainty in volume was 3

Do u think u r right?

Hmmmm yeah I think soo!
In the pastpaers we use dat 0.1 mm value when there is only one reading!
We might had to show dat 0% to get 3 marks!

% uncertainty in mean volume was 1.9%, right? because % uncertainty in diameter was 0.4%.Also, i got 1.54 Hz for resonant frequency and observation was that spring would oscillate with maximum amplitude. Am I right??

How did u get % uncertainty in diamter??
if u used the precision of the vernier calliper to find it than why didnt u use the precision of micrometre to find the % uncertainty of the diameter?

From the first part of the question

 

[Fahimul Islam]

What is the gradient of the last question about LDR? What do we have to do in second question??

1.7 i guess

 

[maths maldives]

what was the precision of the instrument for stopwatch?
i wrote 0.01

 

[Outofideaz]

what was the precision of the instrument for stopwatch?
i wrote 0.01

Wrote the same thing since human reaction time is 0.1 s, 0.01 s will be accurate.

 

[Aaron Rodrgp]

i got

1.?? 1. something??

1.33333?????
