This channel contains a complete list of physics videos, as well as hundreds of chemistry, astronomy, math, and mechanical engineering videos. The physics videos explain the fundamental concepts of physics with some easy to follow examples on how to solve physics problems. The chemistry videos cover all the basic topics of chemistry, the astronomy videos explain the wonders of Earth and our Universe, and the math videos cover many topics in algebra, trigonometry, pre-calculus, calculus and differential equations. The playlists are organized numerically: PHYSICS 1 VECTORS; PHYSICS 2 ONE DIMENSIONAL MOTION; PHYSICS 3 TWO DIMENSIONAL MOTION; ETC. CHEMISTRY 1; CHEMISTRY 2; CHEMISTRY 3; ETC. ASTROMOMY 1; ASTRONOMY 2; ASTRONOMY 3; ETC.
no idea of that , the phase current should be Ia rather than IAB? Pretty confused. phase curent is current differentials from phase to neutral. Line current should be A terminal to B terminal . so....yeah , confused.
dear professor, i obtained a different result {alignc{{(8.987551787 times 10^{9} ` ) cdot (9.64853321 ` )^{2}}over{(12756 times 10^{3} ` )^{2}}}}" "=" " {alignc{{(8.987551787 times 10^{9}) cdot (93.086)}over{1.627 times 10^{14}}}} " "=" " 5.14 times 10^{-3} ` ["N"]
Why does nickel have smaller atomic radius than selenium? (It doesn’t show on the board but I was doing an Assigment and I found out the atomic radius of nickel is smaller than selenium. I thought non metals have smaller radius.
The odds they put on the horse don't matter. Assuming that exactly ONE horse will win, the odds depend on how many horses are in the race. If there are 8 horses, the odds of ANY one horse winning are 1 in 8 AT WORST. With 15 horses, 1 in 15. Horse racing betting has a bad reputation, but your odds are a lot better than they are with lottery tickets, by factors of thousands, maybe millions.
I still don't get it, sir... As you mentioned, the capacitor was initially charged, it should act as a DC battery once removing the voltage source in your diagram. Therefore, the current direction should flow from the top side of capacitor to the top side of resistor and then finally into the ground to supply the power for the resistor. In short, in my opinion, (the current of the capacitor) = (the minus sign) * (the current of the resistor) make more sense in this derivation.
The explanation - while common, is simply not correct. Gravitational redshift is because of time dilation - clocks closer to massive objects tick slower than clocks further away. This is a direct consequence of General Relativity, and is used every day to make our GPS systems work. There is NO energy loss - clocks near heavy objects have lower frequencies (tick slower), but the speed of light is the same in all frames, therefore the wavelength of light closer to heavy bodies has to increase (i.e. shift to the red). What changes is the frame of reference. Any accelerated frame of reference causes time dilation and therefore redshift. Has nothing to do with energy loss by photons overcoming gravitational potentials
Professor I watched a past video and you said tropical doesn’t include precession. Does that mean that sidereal is the real vernal equinox year even though the definition says it is related to the stars? If I was a Virgo constellation in sidereal zodiac would I be a libra right now? The tropical zodiac would be the constellation year.
I still follow you. I want to take a moment to express my deepest gratitude for the profound impact you've had on my journey in physics and science. Your teachings have been nothing short of transformative, and the clarity with which you convey complex concepts is truly remarkable. You have a unique ability to make the most challenging ideas accessible and engaging, and for that, I am incredibly grateful. You are a true gem in the world of science education, and I feel fortunate to have learned from you. Thank you for everything you've done to foster my understanding and passion for these subjects. Your influence will continue to resonate with me as I move forward in my studies and beyond. Even these smaller videos make me reminisce on how many videos I consumed cramming for QM and Modern. Thank you, thank you, thank you.
I've just realised, that in first case, the forse in celling mount is twice as mutch as if the weight was hanging without the pulley block (just only line) - i thing it's worh mentioning :)
THANKS A LOT DUDE I WATCHED A LOT OF YOUR VIDEOS. YOU HELPED ME TO GET IN IOAA JR BANGLADESH TEAM. IT WAS MY DREAM TO REPRESENT MY COUNTRY IN AN INTERNATIONAL OLYMPIAD. AGAIN THANKS.
I do not understand. I understand that same amount of water should go in and go out but this drawing does not reflect that. I ask where are ends of tube? Should be 2 drawings as beginning of process and end of process. is this pipe part of greater system. What does it mean that water coming in to one end of pipe? What is initial state and final state? V1 is fluid coming in? Is it show that V1 came in and V2 have not yet come out??
