Thanx a ton sis!
It's perfect!

sorry you're seeing a reply after so long! Anyway i cant post a pic,but the basics of the diagram are what is shown in the question,plus:
-a meter rule placed vertically "behind" the wire,to measure distance
-micrometer to measure diameter of wire
-rheostat in circuit to keep current constant
and ammeter in current
thats it!
hope i helped!

No it's okay! No need to apologize
Thank you so much! I drew the same thing, except for the rheostat. I dont know how to draw a rheostat

thats decent and nice diagram bro ... thanks for it ....

Thanks, I was worrying whether it would be enough or not - thanks a lot!

are we suppose to do such old p.papers? i did from 2007 to 2012

Quantity doesnt matter if u feel u need to do more u can but i dont think its time to try new things bcoz paper is tomorrow so go through all the ones u have done and u will do great.
And 2007 to 2012 are enough i suppose

Hey.Can someone tell me that how do we find the unit in M/J08 q.2 part(d)?

check a textbook,it'll surely be there!

oh thnaaaku

 

[kiara15]

ok

this is enough...but if u get time do look at planning excercise of old papers

ok

magnesium how to calculate %age uncertainity? abso/measure value*100?
can u tel me procedure and diagram of oct/nov10 p53 q1?

 

[Oliveme]

Hey, i'm really sorry I couldn't post it earlier, I was kinda pressed for time on other matters.
Sorry if the diagram isn't good enough (It looks bad, but in this time, it's the best I could do - sorry!)

Good Luck for all your exams!

I don't know why you're apologizing because that's one hell of an amazing diagram!

magnesium how to calculate %age uncertainity? abso/measure value*100?
can u tel me procedure and diagram of oct/nov10 p53 q1?

yes it is correct...uncertainity / value * 100

 

[kiara15]

fb.junks or magnesium plz tel me how to do whole part e of m/j/11 p52...? ques2

 

[Trash Can]

how to draw error bars when the errors are at the points of x-axis?????in that case,how will be the worst acceptable line??

 

[kiara15]

yes it is correct...uncertainity / value * 100

ok thaaanku god bless

 

[kiara15]

ok thaaanku god bless

can u tel me diagram or procedure of winter 2008 p5 q1?

 

[zsyed94]

Hey.Can someone tell me that how do we find the unit in M/J08 q.2 part(d)?

hey..guys wat is meant by a (compact light source)

 

[lavanyamane]

Hello everybody! Can someone please explain what a signal generator is/ does in ters of Q1 of this paper? Just an overall explanation of what it does will be great, thank you!

[SararaIH]

v = s/t where s=distance, t=time
v^2 = (s/t)^2
so v^2 = (0.05/t)^2
then substitute values of time from each row into the eqn
eg for row 1, v^2 = (0.05/0.046)^2
so v^2 = 1.18


then uncertainty is (max value of v^2 - min value of v^2) / 2
so max value of v^2 = (0.051/minimum time)^2
min value of v^2 = (0.049/ max time ) ^2
subtract these two values and then divide by 2 to obtain uncertainty


Hope that helped

You know, I did this. I did the same exact thing that you did. But then, why does the Mark Scheme say something else?
