Displacement, velocity, acceleration, relative velocity & kinematic equation of motion using Vectors
In this video, we will revise the kinematic motion of chapter 3 using vectors. We will start with displacement, average velocity, instantaneous velocity, average acceleration, instantaneous acceleration and relative velocity along with the direction. Thereafter the Vector form of kinematic equation of motion and its advantage in solving the problems. third equation of motion is a scalar equation while first and second equation are in vector form.

Change of voice by inhaling Helium gas, what will happen if we inhale Helium gas
Переглядів 151Місяць тому
In this video, we will see what will happen if we inhale helium gas, because Helium is a light weight gas compare to air frequency of our voice will increase and become sharper. In other words frequency of a simple harmonic oscillator is inversely proportional to square root of mass. so the vocal cords will oscillate with higher frequency in presence of air.

Hamare iklote bhai ki aawaz ladkiyo jaisi kardi😢😂😂
very good lecture bro thanks
Thank you sir ❤❤❤
Sir when will you start 12th physics
After completing 11th
Great explanation sir ❤
Nice explanation sir 🎉
Hello, Sir.. I’m a PhD student of DU.. I have 11 rock samples , i want to identify the rocks. Which XRD will be more appropriate? Powder XRD or Single Crystal XRD or Table top XRD? And they in working condition?
Single crystal xrd will only help you in a single crystal... but it's a rare chance that your material is a single crystal unless you make it by lattice stacking. So powder xrd will be the best choice if you can make it in powder form.
Floor mounted power xrd and table top xrd will provide you the same data unless you are looking for thin films or RDF radial distribution function measurement in amorphous materials.
❤
Good sir ❤
Iam a bsc sy physics student so i can say | You’re doing absolutely good work ; your way of teaching is also really great. Thank you so much sir
mst
This is so interesting...have never seen such practicals, so nice ❤🎉
Bahut Badhiya
Sir aapne mera debut clear kr diya
Well explained Be continue
Ye video me jyda hi kuch time lg gya tha dyan se dekhna sbhi log ❤❤
❤❤ nice 👍
So many examples and concepts explained and that too in so much detail with fun practicals 🫡🫡🫡
Great explanation Sir...🎉Kya shadi me dulha Dulhan jin badalo me chalte h vo liquid nitrogen hote h 😅🥲
Nai nai fir to vo jal jaenge 😂

Good work
Bhai doctor jaisa mat likho please 😢
At 0:10 it is "sedimentation" and "gradient with height"and at 0:16 it is "Johnson noise in electric devices" Even if you have no equipment, you can simulate it and get help from your friends to animate so it is near perfect. Share in your whole country to lower the cost and improve the quality of online learning experiences. Real data, real models, good practice for statistics and machine learning. Do NOT be satisfied with only telling about things, do them yourself and share with the world. You are very young, in 6 or more decades one person, alone, can change the world. On Wikipedia it is "Johnson-Nyquist noise" Get a few places in your country (or the world) to run "Brownian mirror galvanometer experiments" continuously for decades. You should eventually make it sensitive enough to correlate with weather, seismic, with magnetic fields, and with gravitational potential and gradient fields (vector tidal from sun and moon), infrasound, and much satellite and regional data from new networks. I suggest Franck-Hertz as well. Build global communities to go as deep as you can, and you should find that all that "quantum noise" is a mixture of magnetism, electromagnetism, gravitational (potential flows and local gradients)the electromagnetic field of the earth, and signals from the solar system and the universe. Looking carefully at the very small, and tiny, over long time, from various site on earth and the solar system - for decades and centuries will be a good way to share exploration and careful methods. Please do not get proud and greedy. If you put $Thanks one day, people can more easily thank and encourage. Help Bangladesh and other countries. The potential of all humans is the same. Their paths in life might be different but their core humanity is the same. There are poor people in the United States, in Europe, China, Africa - in every country. And many "rich" countries and organizations who become too proud to listen and share and learn. I have always felt bad about Bose and the way he was treated, but also how he acted. Most of the universities in the world have the wrong goals and methods now. That is why I say not to chase prizes and false goals. I think Bose was cheated because he followed fame, not his heart. If you create and expand new fields, then there will not be competition doing completely new things. You will only be limited by your willingness to share most effectively. Do not waste billions of human years of your country's capabilities fighting and arguing. Rather pick good things, do them well and see what happens. milli is yielding to micro, to nano, to pico and femto. There is not a lot of competition there, if you do not waste time on games and entertainment, fame and money.

Well explained sir :)
Best sir
Good
Good video
Sorry sir but as being a future teacher aapko y kehna chahti hu ki aap thoda bada likha kijiye Or thoda flow m kraya kijiye vrna aise students ka interest nhi bnta Or division of board is also an important part of teaching learning process. And thank you sir aapki video se mera doubt clear ho gya. 😊
Yes 😅 these were my starting videos....they are in low quality which I didn't removed. But later I got some confidence and improved. Thanks for your feedback 😊.
You are really amazing..... Keep it up
Nice explanation 😊😊
Tq sir
thank you so much for his video sir
Thanku sir ❤
Thank u sir.. It was very helpful.. ❤❤
Thank u sir, i searched the whole utube & only u explained clearly with derivation and cleared my doubts 😊
Thanks....and please help me to share my content 👍
