Physics paper 34

So no LED n LDR stuff eventually came right??

 

[Sandhya Mahat]

no, i got the % difference of about 8%.

 

[Sandhya Mahat]

The relation ship wasn't right the percentage error was above 10% mine was 19%

no, i got the % difference of about 8%.

 

[abdulmoizmehmood]

hello, guys what were the resister's connected to x and y? can anyone plz tell me?

 

[angelpari]

no, i got the % difference of about 8%.

me too..

 

[Hassi123]

no, i got the % difference of about 8%.

I got 8 % woah

 

[MoonShock]

I got a % difference of 5.6!

nope

 

[Sandhya Mahat]

I got a % difference of 5.6!

maybe u took repeated readings in d, but i forgot to do so....

 

[Bulltyro]

My percentage difference was %0.69

 

[confused123]

My percentage difference was %0.69

wow very accurate

Guys is it ok that i convert mm to m? So for k i got large numbers
Also is my limitations acceptable?
Zero error on micrometer
Parallex error when reading angle
Not enough readings
Can be high friction on pin, or the hole is uneven, so the pendulum stops before its intended angle

 

[Sandhya Mahat]

I converted mm to m, and kilo ohm to ohm... Graph plotting all were on the basis of dis... Am i screwed?????

 

[Bulltyro]

No Sandhya, you are not screwed.
As long as your gradient value is correct and the direction of the line is correct and and you plotted all the 6 points.
If everything is according to your recorded data, you will get some marks.

Nope... I did that too! But I know it's fine.

My list Of errors and Improvements:

1. The wooden block moves too fast so difficult to measure angle. We need a slow motion camera.

2. There is friction b/w the nail and the wooden block so hinderence in oscillation. Use lubricant to allow smoother oscillations.

3. The wooden block might be released with some force so use of electromagnets or any general holder for release with equal force.

4. 2 readings are not enough to obtain an accurate value so take more readings and plot a graph.

My paper was extremely messy and my sir was like they'll deduct marks. IS THAT TRUE??????????????????? :/

 

[Mattman]

Do they accept parallex/zero errors?
