Is it worked

[@mjozana5455]

Best tutor in Mathematics and Science

[@310EMT]

Wow what are the odds. I just learned about this today in Gen Chem 1. So I did a youtube search and you just happened to post this video today! Thank you for doing what you are doing! I'm watching all of the videos that pertain to what I am learning in class.

[@cdancecoaching]

I agree with everyone here who says that you are the best tutor (and this isn't an in-person experience).

[@alexkarout1586]

Thank you for the video sir, this should help me with calculating discrepancies from theoretical and experimental values in physic experiments

[@natu.d9546]

Wow!! this video is amazing!!! Please keep doing what you are doing

[@mahmoudsleem5505]

You are the best tutor 💘❤️‍🔥

[@ivanjdas4872]

This channel is so much underrated.U r a Noah for the students.

[@frosti8787]

are you referencing genesis?

[@BadBoy65t]

best study channel

[@Mathicalminds]

Impressive ❤️🔥

[@stephengayton5636]

In the first question shown surely the estimated uncertainty is 0.05 as your best estimate is half of the finest division so 24.55 or 24.45?

[@manavjitsinghdhaliwal2478]

If I am not mistaken, when you measure anything on a ruler, you are taking to values and then subtracting them from each other, which would mean you have an absolute uncertainty of 0.05 + 0.05 = 0.1

[@AinaAkorede]

Wow😮 I love the way u think

[@joshuachisha424]

Thank you so much... but i have a question, how exactly are we suppose to determine the estimated uncertainty?

[@yoisme6695]

From my understanding feel free if anyone feels that I am wrong to correct me as I’m only in grade 11 and still learning all this myself but I believe the estimated uncertainty is found front where lowest possible measurement so for example in my group student experiment we were measuring based on temperature so due the the thermometer we were using only being able to go down to 0.01 degrees we used 0.01 when calculating our absolute uncertainty as it’s the lowest possible measurement that we could have potentially gotten sorry if that’s confusing but hopefully it helps

[@macewindu4411]

Basically you look at the last significant digit/figure of a number and it's position will determine the estimated uncertainty, e.g: 25689cm +- 1cm, the last significant digit in that number is 9 and 9 is in the ones spot so we put +- 1. e.g 2: 25680cm +- 10cm, 8 is in the 10nths spot so the uncertainty is +- 10

[@macewindu4411]

btw 0 is a significant figure when its in the middle of numbers, never at the begging or end of a number, e.g: 8980808, the zeros are significant figures, e.g 2: 099, 0 is not a significant figure

[@BeatriceKim-d1c]

What for !

[@dreadslord7241]

I’m the second Thanks for updating us about this

[@lukedowneslukedownes5900]

No idea what this is used for but interesting thank you

[@michaeldonatelli7166]

this is in the first chapter of my physics class.

[@yoisme6695]

It’s used in most sciences especially experiments I’m using it now in my student experiment in chemistry

[@ratnakhadka8938]

please make video on cubic Function just like your explanation no teacher can give

[@kamyarphysicsschool5065]

Great! you can also see my lesson in topic. It may be a different approach. Update me about your opinions.

[@salmannaqvi2267]

❤thanks

[@dixincider7817]

good vid

[@cristiangarciaperez3537]

why do we do spheres differently and not just (uncertainty/ measured volume)

[@ZamlaH]

Thank you❤

[@RaniaArar-v9c]

I LOVE YOU

[@walebelayneh2892]

if there is x+-y, x is the true(actual) value not the measured value

[@mohamedsillah9885]

Sir how could I calculate the uncertainty of area of the circle whose radius is giving?

[@DanStep-yo3pv]

So the area is pi * ( r )^2. Since r is to the power to 2, the general rule for uncertainties to a power is that its PERCENT uncertainty would be multiplied by 2. And that is it! And yes. I am a year late.

[@rdc.4]

BROOO did u know nowww is 2 AM in Europe,

[@cindynicolepotter7788]

pslpslspls don't get mad (pls dumb it down for me) why is it that at 4:28 the uncertainty is 1 but 8 is the number at the ones place? (do you base if off the last number place and not the value itself ? so it would always be 1 but like the decimal or zero is the only thing that will change?) im so sorry TT^TT OMG I GET IT NOW WAHAHAHA
