Conservation in Particle Interactions
That means that during charging and discharging the the currents decays/decreases in both cases.??
Why should we consider the radius of the earth?
thank you so much!
Thanks! Helped massively w physics exam
Hubble's Constant can be easily calculated (fixed exactly) using ONLY the speed of light (C) and Pi 2 X a megaparsec X C, divided by Pi to the power of 21 = 71 K / S / MPC. This equation comes from the "Principle of Astrogeometry". Ho is fixed at 71. No tension, no waffle required, just simple algebra.. David Hine
So is the elastic potential energy the same as work done on the elastic?
No
Sharma sir ne bola isliye dekhri
👍
watching this for my exam tomorrow in 2024!!!! good luck future exam candidates! :)) x
Thanku so much... I was looking for such explanation
its over i give up on suvat bruh
Thanks!
Read out this comment sir
i love u mr cowen👍
I’m very uncertain even after watching this video
Bigger stars tend to be cooler than smaller stars, no? The sun is hotter than a red giant despite the red giant being bigger
These videos are so helpful, thank you :)
Great Video Cowen Physics; much appreciated!
Straight to the point explanation. Thank you so much!
Helpful
🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣 the voice
Thank you! This is helpful!
My guyyyyyy
mate these videos are actually pretty good
Thank you very much!
Very clear and concise.
Such a helpful video! Thank you so much!
Sir I didn't understand where did you get 9.81 as your acceleration
the earth gravitational pull
i still dont get it:(
Me neither, we can struggle together 😢
GOAT🙏
doing physics and have to learn the metric system kinda sucks. Not the system itself just wish America would teach this in middle school because almost all the rest of the world uses the metric system
When you make a mistake in the first 5 seconds it's over.
What mistake would that be?
Thank you
ily man
Thodi hindi bhi bol liya karo master ji
Where did the cosine come from?
Thankyou sir, u made it easy to understand...
Its becomes very easy for me by watching 👀 😌 your video
if r=distance between us and the object in the last equation wouldn't it change to 4pi2r
Sir i have a confusion in this topic but i can saw your vedio then i am understand this topic properly : thanks for guiding 🥇
Very good explanation. Thank you.
WHO IS HERE AFTER RAJWANT SIR CLASS?
Shouldn't the field lines be pointing North to South?
My textbook uses sin instead of cos. How do I know which one to use and when?
the cos is used when the area and the magnetic field lines are perpendicular to each other, and we take the normal to the area, and we compare the normal line of the area to the magnetic field lines.
Thanks mkn
Very useful for demonstration in physics class. Thank you so much.
This is a FANTASTIC presentation that gathers all the key concepts & terms in one place. I never realized Faraday's Law could be derived in such a 'common sense' series of steps.
Concise yet comprehensive. Excellent. Thank you!
i didn't understand the term "flux linkage" now its crytal clear
This is super helpful, thank you so much!
