6. Class 11th Physics | Constrained Motion | Simple Pulley Constrained Motion | by Ashish Arora

Now we’ll study simple pulley block constrained relations. you can simply say in pulley systems. these are developed. By analysing. Loosing and. tightening. of strings . due to . motion of blocks . so just be careful about , a pulley block system like, if we just talk about the simplest system which we can […]

Computer Networks: Crash Course Computer Science #28

Hi, I’m Carrie Anne, and welcome to CrashCourse Computer Science! The internet is amazing. In just a few keystrokes, we can stream videos on Youtube — Hello! — read articles on Wikipedia, order supplies on amazon, video chat with friends, and tweet about the weather. Without a doubt, the ability for computers, and their users, […]

Amplitude, period, frequency and wavelength of periodic waves | Physics | Khan Academy

In the last video we talked about the idea that if I start with some type of a string there, and if I were to take the left end of the string– I could just have equally have done the right, but if I take the left end of the string and jerk it up, […]

Phase diagrams | States of matter and intermolecular forces | Chemistry | Khan Academy

All of the phase changes we’ve been doing so far have been under constant pressure conditions, and, in particular, with the problems that I’ve been doing with water phase changes in the last couple of videos, it was at atmospheric pressure, at least at sea level atmospheric pressure, or at 1 atmosphere. So it was […]

Princeton University’s James Peebles, 2019 Nobel Laureate in Physics

[UPBEAT MUSIC] JAMES PEEBLES: Thank you. Who are you all? I was awarded the Nobel Prize for a lifetime of contributions to the advance of this subject. I have been working in cosmology since 1964. I’ve been in this subject and seen it grow from a very small science to an immense science — [STUDENTS […]

First Shifting Theorem – Laplace Transform – Engineering Mathematics 3

First Shifting Theorem – Laplace Transform – Engineering Mathematics 3

Hello friends so today we are gonna learn what is first shifting theorem of Laplace transform so if Laplace of function of t is given as function of s then the Laplace of e raise to minus AT into function of T is equal to function of s plus a so it means that whenever […]

Induced current in a wire | Physics | Khan Academy

Let’s say I have a magnetic field popping out of this video. So these little brown circles show us the tips of the vectors popping out of our screen. And in that magnetic field I have this wire, this off-white colored wire. And sitting on that off-white colored wire I have a charge of charge […]

Hackers & Cyber Attacks: Crash Course Computer Science #32

Hi, I’m Carrie Anne, and welcome to CrashCourse Computer Science! Last episode, we talked about the basics of computer security, principles and techniques used to keep computer systems safe and sound. But, despite our best efforts, the news is full of stories of individuals, companies and governments getting cyberattacked by hackers, people who, with their […]

Conductors and Insulators | Physics | Khan Academy

– [Voiceover] It’s useful to pretend like all materials in the universe can be broken down into a category of insulator, electrical insulator, or electrical conductor. That’s not completely true. There are semi-conductors and super conductors and other exotic forms of electrical materials but for most introductory physics classes and problems and tests, you can […]
