Yup.


The general formula is:
[Lg(Max)-lg(min)]/2

thanks a lot

No problem

 

[Alevel Romeo]

and i am almost ready to blast the test tomorrow and i need help with aparatus!
please someone post the list of aparatus we are going to need like what should i use to measure the velocity of wind?
what should i use to measure magnetic flux density? and so on!
please please!
i need the list of apartus! and please reply fast! because test is really knocking at the door!

 

[AlishaK]

No problem

Can Someone Explain the working Of GM tude
http://papers.xtremepapers.com/CIE/...and AS Level/Physics (9702)/9702_s03_qp_5.pdf ( Its the second Question )

Independent and dependent variables? o.o

Independent variable - varying the Angle
Dependent variable - measuring the The angular speeed

But i have no Idea to vary and measure the variable

btw how do we vary the angle? o.o
And Thanks

mic is supose to be out
its a question from w 03 or 04

 

[TheBeast]

how do u put hall probe inside a coil...

 

[SalmanslK]

mic is supose to be out
its a question from w 03 or 04

no point in mic being outside..the question is the effect of pressure on sound.

Guys....what exactly is right. :/

 

[magnesium]

how to draw the error bar when the errors are in the x-axis???are they sideways??? also,how to draw the worst acceptable line then??is it from the extreme right (highest) of the first point to the extreme left of the last point???plz reply anyone..ASAP..plzz help..!!

error bars in x axis are horizontal...worst acceptable line Should pass from left of top error bar to right
of bottom error bar or right of top error bar to
left of bottom error bar

Q2 (b) When t=time for 10 osc. T=time for one.
So for eg:t=19.6 (+-) 0.2 So in order to find T we divide 19.6/10, do we even divide the error also by 10 ?

Q1- How do we increase the speed? Guide me with this exp.
SalmanslK PLease Please.

for question 1

( log(19.8)-log(19.6) )*(log(19.6))= 5.69*10^-3 -------> 0.005 or 0.006


question2:
(omega)w= angular speed/time taken

for one complete rotation measure time taken(T) and hence; w= 2(pie)/T

for question 1
log 1.98 - log 1.96
it was the idea suggested by a brother.but i m also confused.

Someone suggested me lg(max)-lg(min)/2 :S

can anyone tell me how to connect cro and signal generator to a circuit with diagram?

GUYS you can get the uncertainty both by subtracting log of mean from log of max OR subtracting log of minimum from log of max and dividing by 2!
