Thanks so much I don't know what I'd have done without this 😅🙏🙏🙏
Thank u sir
Thank you
hi sir could you explain when you mentioned, at time 3:50 in the video, about: "as it got colder, the resistance increased so more voltage, hence more power flows through the heater" I have a few questions here: firstly, did we still consider the current as being constant when telling about power, P=IV? or does it change when a heater is attached in parallel? Secondly, does it require a high power for any component eg. lamp, heater and say relay coil, to turn it on? Please help sir, I have my IGCSE exams in just 1.5 months from now, and I am very concerned about this doubt as I couldn't understand teacher's explanation on this topic except you, please help!
How to hurt ypur brain
Awwwnn, thanks so much for the simple explanation. ❤
Of all my months I physics I can't seem to understand moment
What grade u working at
THANK YOU THANK YOU THANK YOU
just what i was looking for
am so much grateful sir....u re such a brilliant and good teacher..can u please teach electrical engineering...like a playlist..u will impact a lot i guess. Thanks so much
Yh but it's easier
Where did he get f x 2😮
Thank you.
Why can't there be that channel that explains every igcse topic ever for every subject, guess there can't be a perfect channel for that
Thanks <3
For question 5 i think the answer must be 16.7N
I tried to understand these concepts for the last 2 weeks in class but failed to understand but after seeing this video I understood it better. Thanks a lot sir it really helped me🫡🫡
The great teachers are always on TH-cam and the trash ones in the classroom. Jesus.
can't believe it's over 7 years but you taught straight to the point ! Thank you !
But sir, why is it 0.3 for qs 5?
Luv u
in a.) can we also write increase in current???
No
question 4 Why did we include the 2m distance with 80N in the anticlockwise moment even they're on the right side of the pivot? I'm not even sure I'll get a response 😢
Any traumatized 2024 students here?
Present😂
Here 😂😭
😭😭
Thank you so much
Why not 8 their
The last question I didn't follow the perpendicular distance from the pivot but I got the same answer😂 like: 1000×0.5=F×3 500=3F F=500÷3 F =167N😂
I'm having issues trying to grasp the 3rd method, how does the magnetic field coming from a particular pole (Say North pole) changes sign to negative. I'm believing that as the magnetic field cuts across the areas of the coil it changes, thereby producing current. But when it rotates how does it really change to a negative by just flipping it over 😩
Thank you sir, you really helped me especially with question 5
hat trick for you teacher from libya i passed the gcse exams because of you
Is it a must you write the clockwise moments=anticlockwise moments cause of you don't follow that you still get same answer
Why have 10 there instead of 5
acc saved me thank you
This is seriously underrated, it's a crime for this few people to know about you!
what program are you using for drawing?
i finally understand this topic... tysm....😀😀✨✨✨✨✨✨
Where is the center of the wing's turn? Is it relative to an observer on the earth (ground) or is it somewhere else above the wing somewhere in space? Does the total lift vector (moment) point to the center of the turn or does the horizontal vector (moment) determine where the center of the turn is? If it is not with respect to an observer on the ground, then the center of turn is not pointed by the horizontal lift vector. If this is so, both wingtips have no relationship to the ground and thus, both wingtips are flying at the exact same airspeed, with respect to the airmass, right? Wrong?
Thank you sir I was struggling sm
This questions are way to simple bruh compared to the ones i'm finna get tomorrow.
Ik right
why didnt he divide by 0.6 for the first one tf
This videos helps me .
Thank you very much
Great video and explanation! I have a question though. Why if you alter the shape quicker does the E increase, like you said, and not decrease because its in the denominator? Greeting from Greece!
life saviour.
Thank you very much...I've been battling with moment calculations for the past two years..😢..thanks for making it seem as easy as pie... you're a good teacher 😊
You have no idea how this helped meeee. I was trying to understand this thing for a whole hour- Thank youuuu
Great job mate!! I find it funny how 'ball' and 'bowl' sound the same when you say them lol
Thank you soo Much !!!!! This helped a ton !
Did anyone else’s physics teachers not teach this???
Excellent
