Lessons, experiments, skills, and animations for learning physics at A-Level standard. Videos will cover all of the content for A-Level physics with some videos going beyond; some pre- and some post-A-Level.
A-Levels are a UK education standard but I hope you still find these videos useful even if you're not taking A-Level physics.
Hello, great video. One question, why isn't atmospheric pressure added to the pressures? I understand that it is a manometer and only indicates relative and not absolute pressure of the gas.
Veo comentarios de muchos años atrás y aún en este año (2024) me parece estupendo este vídeo ¡Excelente!. Quiero hacer la salvedad que no soy de comentar ningún vídeo.
wow EPIC music and EPIC video quality I was learning and shaking my head at the same time lol keep it up this is the highest educational video quality I've ever seen
Is MRI based on getting things going and then turning things off? So if you turn one thing off you can get signal from proton precession going from IN phase to OUT of phase, but if you turn this other thing off you can get signal from the relaxation of the change in angular momentum of the precession itself, independent of phase. Is that what this is all about? And which one is T1 and which one is T2 again?
