AS PHY PRACTICAL 33

[A*(a*)]

I knw abt multimeters, Ammeters and Voltmeters would be easier to use I guess with lesser options

 

[kelly sheers]

anyone who doesn't know about a rheostat

 

[blueberryyums]

No news on 31?

 

[Nofel Mehmood]

Hold on guys, is everyone doing edexcel? :/ I'm confused lol

 

[A*(a*)]

And what is the marble here? Is it the material marble of which the slope is made or a small ball? if it is a small ball as someone said then what do we have to do with the other ball given?

anyone who doesn't know about a rheostat

youtube is blocked..

 

[A*(a*)]

Exactly ,confirmed. Basically the height of the slope is to be changed.

If it is Q2 as u said? why aren't the people confirmed that we do not have to set the apparatus.?

 

[blueberryyums]

I guess I'll just study every paper 3 tonight before the exam. No idea on my apparatus.

Good Luck everyone for your practicals.. May Allah grant you all As and A*s grades in all your subjects

We don`t really know what the question will be. All we know are the instruments. Baaki kal par kya sawal aata hai

why is that?

you have to use only the marble.
and for improvements, you can say that, use a metal ball instead of marble and use electromagnet to release it

 

[falcon678]

why is that?

v pakistanis...itz blocked here thnks to our old Government.. n new one isnt paying attention to unblock it...

 

[MustafaMotani]

why is that?

its blocked in pakistan ..

Exactly ,confirmed. Basically the height of the slope is to be changed.

how would u chnge the height of the slope

 

[falcon678]

how would u chnge the height of the slope

by tilting the plane?

 

[MustafaMotani]

So according to that video ... when we have to vary resistance we just connect it to the circuit with upper connection .. ?

 

[h4rriet]

No... for the "k" question you actually find the percentage uncertainty for the two different values of "k" and compare it with the percentage uncertainty of the independent variable. if the values of "k" lie within these percentage uncertainties, then you can say "k" is constant and the results do support the relationship...you cant just compare the two values and come up with a conclusion like that lol

Err, I'm afraid out teacher never told us anything like that.

 

[aleezay]

isn't the least count of a meter rule 0.1 mm, which is 0.01 cm and thus uncertainty = 0.005/calculated-value ?

calculated value is a measurement. so you multiply .005 by 2 to get .01
