Physics practical tips

Hey everyone you might like to check this out:
https://www.dropbox.com/s/p4gvt356bc548jj/9702_Physics_Standards_Booklet.pdf
this is example candidate response checked by CIE examiners for physics. It has practical papers as well. there are tables and graphs along with the mark schemes and comments of examiner.

will the ammeter be giving reading in mA?

Well u gotta see the dimmer. It's already preset by the supervisor. If it's against mA then the value would be in mA, and in microA or A if it's against uA or A respectively. don't get confused with the values next to the unit, that's just the range.

I found a resource that might be helpful for the physics practical.

How to justify on significant figures?

How to justify on significant figures?

Calculated data must have the same number or one more than the number of significant figures of the raw data.

 

[Fahm Deen]

In some cases we see that there is no mark for parallel error however in some there are.
Considering q.2, when does this happen?

calculated data should contain same no. of sig. no. as the raw data ( unless they dont mention about changing the sig. no.)

avoid such kinds of error , its better!!

I have some sample papers, and it is stated by the examiner that one more is also acceptable. However, if you want to be on the safe side, go with the same number of figures.

exactly, its better not to tke the risk !!
best of luck bro

Whats the uncertainty of venier caliper and micrometer screw gauge

 

[Risay1234]

Any idea wats coming in p32 today?? ,apart frm electricity not being included any further clue??

Guys for finding the time do single oscillation .. How do we take the timing ? Like we take for 10 oscillations and then divide that the by 10 or what?

I think its like this---->T= t(time taken for 11 oscillations) /no.of oscillatons (11)

I think its like this---->T= t(time taken for 11 oscillations) /no.of oscillatons (11)

And then we repeat are readings drawing the table .. And take the reading in the same way right?
Thank youuu

HELP!!
For the vernier caliper .. This is how u do it right?
(Main scale reading + coinciding value /10 )

PLEASE REPLY !

PLEASE REPLY !

vernier scale reading+(coinciding value x0.1mm or 0.01cm)
