Physics: Post your doubts here!

[FairyTail]

Well guess what I just noticed that u don't go to page 1 for the recent messages so I was always in page one every post everything was like, a few years behind I was like okaaayyy so most of people here are inactive till I just for fun pressed the 879 th page button and found out this guys pls if possible fix that it's pretty confusing to new people like me

Any predictions for the Physics practical on tuesday? For those appearing in variant 33.

same same anyone knows what's coming for tomorrow

Ohh sorry I didn't see the answer to the question
But uhmm your sure it's pendulum and electric circuit cause I don't wanna waste time on something that might not come I'm not saying your lying but just to super confirm.....and by the way the phy paper 33....right

Is first question electricity or pendulum?
Any specific practical tips ?

 

[MARZ132000]

Magnets and springs

Wait how do you know?!

 

[hancy pandey]

look at previous messages ....Pendulum and electricity was precdicted

I'm talking about 31

Sorry bro..No idea..I'm talking about 33 .Its scheduled for tomorrow

Plz someone tell me if the l.c of vernier caliper is 0.1mm so what will be the absolute error in one MEASUREMENT?
PLZ its urgent

It can be either 0.01 cm or 0.1mm both are correct but 0.1 mm is used mostly.
Absolute error in one measurement is 0.1 mm

It can be either 0.01 cm or 0.1mm both are correct but 0.1 mm is used mostly.
Absolute error in one measurement is 0.1 mm

And absolute error in micrometre is 0.01mm...right?

 

[hancy pandey]

%uncertainity= least count divide by measured value multiply 100%

 

[A*****]

Like l.c for metre rule is 0.5mm but for 1 MEASUREMENT we take 1mm...so I was asking if we do the same for caliper

 

[Hamnah Zahoor]

And absolute error in micrometre is 0.01mm...right?

Yes.

 

[hancy pandey]

Hey folks, any predicted Q for tomorrow practical?

 

[A*****]

Hey folks, any predicted Q for tomorrow practical?

Potentiometer for q1 maybe and oscillation for q2

In vernier caliper we take measurement only once in case of a metre rule it's taken twice.

Hey guys how many are freaking out right now cause u didn't study in the evening cause u thought u had time

Wait...shouldn't the lc be halved then?

 

[Hamnah Zahoor]

Ok ....You are confusing me now.
