physics practicals....help plxx

[hassam]

any one could give me some hints abt how to record data....i mean sig figure and d.p and stuff like that.....secondly i am having a hard time regarding setting up circuits......any hint on how to set up circuit or any useful video abt this

u need to write in 3 sf!
and abt ckts
u start from one point ie the point where there is +ve terminal of the battery and go on arranging in the same order!

Assalamoalaikum!!

u know how i do this is...keep the fig. given to the left...make sure ur table is clean and not messy..then as princess said start from the +ve terminal and proceed according to the fig. try arranging it in a similar way...and do it neatly..i mean dont mess things up because the moment u have all the wires and everything ...u get confused...

well about the significant figure(sf)...
u need to see the sf of the recorded data... for eg..if u have recored time for 10 oscillation up to 2 sf, u can write period of oscillation upto 2 sf or up to 3 sf (ie same number of sf or 1 more) ....
this concept applies to all similar calculations...
further if u have to calculate the data from two recorded data..for eg... if u have to calculate the product of lenght (L) and time (T), record these quantities to the same number of sf( ie if lenght is recorded in 2 sf, record time also in the same number of sf- 2sf-) and apply the same concept....the product of T and L can be up to 2sf or 3sf in this case(the case is the eg).
Hope it helped
