@@mizukun9037 i was searching for em rn 😭😭 they aren't so hard tho I suppose I'm just trying to memorise the possible errors and uncertainties rn to gain those 8 marks
sir really appreciate your efforts, thank you so much for these tips, May Allah reward you for this, and please wish me luck as i have my exam tomorrow
Sir on 23:37 u said ke small division le te h as absolute uncertainty but if u are taking reading from two point u double the absolute uncertainty if absolute uncertainty is 1mm we double it to 2mm.
Jitna apne raw data jissey calculation karahe ho uske significant figures hain it is preferred ke utne hee s.f mein calculated data yani uncertainty wagera ho
Sir 27:32 main apnay kaha ke 15% se exceed kare tou reject karein hypothesis, tou sir zaroori hai ke har question main 15% se zyada ho percentage uncertainty tou reject kardein or this rule is only for this particular question? Pls do reply sir.
I wanted to ask that in some places I have seen that k is to be compared with the percentage uncertainty of the raw data with highest uncertainty and I also read that it can be compared with the total experimental uncertainty by adding all of it And you said to see the 15% because it was in the question What if it is not stated in the question Which method do I use???
Do we have to give the answers in SI base units in AS Physics 9702 Practical exam or according to the unit of the instrument from which we are measuring like for e.g. meter rule which is in cm so we will also give the answer in cm to 1dp or can we also give answer in m by converting cm to m?
For meter rule you can give answer in "cm" "m" or "mm". You have to just make sure that the decimal places are correct SI units don't matter such especially when measuring things. For example, a 78 "mm" measurement can also be written as 7.8 "cm" and t can also be written as 0.078 "m"
@@AlphaLearning-dd4mt for if we write answer in any unit it will be acceptable if it is written to correct number of decimal places like 1dp for meter rule in cm and 2dp for vernier calliper in mm right?
hey!! I've been seeing your videos quite alot now especially cause its the exam season. Could you please make a video on Edexcel IAS Unit 3 (paper 3) Physics Alternative to Practicals?
Thank you so much for this video! But I have one question, isn't the precision of a stopwatch to 2 d.p so why should we write time to 1d.p and not 2d.p?
sir mainay q2 ki width aur thickness exchange ker di main pehlay thk ker rehi thi lakin main diagram ki wajah sai confuse ho gai tou kia meara q2 wrong ho jai ga plz answer me
p33 guys lets come back when were done w it
I'm taking it too.. hots are it might be circuits or smth to do with balancing rulers n angles
@mizukun9037 yeah the latest is that it's moments most prob bec of the ruler and masses and there's a chance for oscillations asw

Thx a lot sir it was really a blessing indeed
well explained! very helpful
best explanation compared to others
best video ever
Thank you sir
Thanks a lot sir ❤❤❤❤❤
It really helped......❤❤❤
sir how many significant figure/decimal point for percentage uncertainty, value of k1 and k2, percentage uncertainty of k? i appreciate this video sir

It is a permanent rule for every question.
thananksss a lot sirrr

sir kindly explain 1 question regarding dc circuit for p3 as well ty.
Am I the only one watching
sir , what is the smallest division on screw guage and vernier?
For micrometer screw gauge: 0.01mm
For Vernier Caliper: 0.1mm
Sir so if we need to find percentage uncertainty in micrometer screwguage then we will use 0.02mm/ans ×100? Please reply
thanks sir
upload a2 play list for all chapters as well if possible

Do we have to give the answers in SI base units in AS Physics 9702 Practical exam or according to the unit of the instrument from which we are measuring like for e.g. meter rule which is in cm so we will also give the answer in cm to 1dp or can we also give answer in m by converting cm to m?
For meter rule you can give answer in "cm" "m" or "mm". You have to just make sure that the decimal places are correct SI units don't matter such especially when measuring things.
For example, a 78 "mm" measurement can also be written as 7.8 "cm" and t can also be written as 0.078 "m"
@@AlphaLearning-dd4mt for if we write answer in any unit it will be acceptable if it is written to correct number of decimal places like 1dp for meter rule in cm and 2dp for vernier calliper in mm right?
yes. And make sure to continue those units ahead in the question.
Sir I don't get the point that 15:42 that plotted point must be accurate to better than half of a small reading??
means the maximum error you can make while plotting a point on graph is "half small box"
Hello sir the Download link isn’t working on the website
sir, the vernier caliper in cm gives reading to 2 dp place right? and micrometre screw gauge to 3 dp in cm?
yes! But also double check the instrument in exams.
thank you sir paper in 3 days 2024 session
Best of Luck!
for the percentage difference in Q.2 do we not divide it by the larger value of k?
no! We take average.
sir how many significant figure should i give for the gradient and y-intercept
give the exact value that you get from graph.
hey!! I've been seeing your videos quite alot now especially cause its the exam season. Could you please make a video on Edexcel IAS Unit 3 (paper 3) Physics Alternative to Practicals?

yes

@@ahmedsamdani1334 that's right nothing wrong in it
Sir can we use 0.01s as small reading on stopwatch for absolute uncertainty
no! Absolutely not.
Stopwatch uncertainty = 0.2-0.5s

can you upload it online and give link?
Thank you so much for this video! But I have one question, isn't the precision of a stopwatch to 2 d.p so why should we write time to 1d.p and not 2d.p?
coz that last dp cant be accuraetly measured by us due to our rcn time hence we only take till 1 dp

sir ek question tha...question 2d mein kai baar percentage uncertainty nahi diya jaata. tab kaise calculate karte hain ?
then you assume it to be 15%

sir what if the percentage of k comes out as 14.8 then what do we do?
14.8 is less than 15. Hence approve the hypothesis.
Sor the uncertainty u said about stopwatch that is 0.2 -0.5s is percentage uncertainty or it is absolute uncertainty.
absolute
