[@zhelyo_physics]

Thank you so much for the kind comment!! So much appreciated!

Great vid! Is there a different video for the topics like half-life, nuclear fission/fusion,ect?

[@sqwekyrcon1049]

Great video, have you got any revision videos on nuclear fission/fusion, e=mc^2 and binding energy?

[@zhelyo_physics]

Thanks! Stay tuned, working on that one, will probably be out next week

@@zhelyo_physics thank you! youre saving my grade this year, this whole playlist is super helpful, ive went from an E to a B so far just from watching the videos and practicing, thanks!

hey
at 6:38 where did the -ive sign go?
the one with lambda
amazing contettt!!!!

[@zhelyo_physics]

So I have multiplied both sides of the equation by -1. This gets rid of the minus sign but also flips the ln. Hope this helps!
