May June 2006 question 1 Diagram

 

[afoo.666]

This is for the October - November 2010 p52 question, 2(a):

If you mean the first part where you have to find out the gradient of the line of lgT on the y - axis and lgL on the x - axis, the gradient is b because taking log on both sides, we get

lgT = lgA + b * lgL

If lgT = y and lgL = x, then we have

y = lgA + bx

So gradient is equal to b.

Good Luck for all your exams!

Thankyoouu soo much!!

Ok for that u need to arrange the equation in form of y=mx+c.
If the problem is with log.Then study its rules or tel me the question i can explain.

My teacher gave me rules of log. How and when do we know where to use them? :/

How to calculate value of T in the table?

 

[afoo.666]

Error bars are drawn only on those points which are passing through best fit line?

 

[Anika Raisa]

Here ppl how are u preparing for ur p5?
I m really confused as to how to... i hv gone through some past solved questions n came up with a note of ma own n thought of sharing with the generous brother and sisters here! I am too lazy to do the unsolved papers or go through all papers so yeah pls guide me on how i cn prepare better!
BOL ppl!

Nope error bars should be drawn for all the points and usually u are given exp with few anomalies!

 

[Anika Raisa]

I need a diagram for this! PLEASE! HELP!

How to calculate value of T in the table?

The question statement (Page 5) mentions that:

"The time t for 10 oscillations is recorded for a pendulum of length l. The period T of the pendulum is determined. The procedure is then repeated for different lengths."

Therefore, if the time for 10 oscillations is t, the time period of the pendulum, which is T, should be t/10.

So the values of T in the table should be 1.89, 1.79, 1.67, etc.
Sorry if i've misunderstood - were you referring to the uncertainties in the values or just the values of T themselves?

Good Luck for all your exams!

Excuse the irregularity as in bakataraness

Thanks so much!
But you know, I suck at drawing circuit diagrams. Do you know how I can get better?
And do you know where I can get diagrams for certain apparatuses?

 

[SararaIH]

Do we have to draw the diagrams in pen or pencil? :/

Thanks alot. No i just wanted values of T.

Anika this was super helpful! Thank you so much!

Lol I know it's a stupid question but I was confused because all my teachers in school said that I have to draw the diagrams in pen. So I don't know which one is right :/

please can some one solve me the gradient part please, with error
can we get error in negative.
as i am trying but getting error in negative please help

 

[Tammy Hin]

Can someone post how to draw diagrams for the first question form 2007 to 2012 please? It will be really kind of you.
