Thank you, prof. you're awesome ♥
your videos help me pass physics at university. thank you so much. you're awesome !
That's cool! How did the rest of your studies go?
It's always good when you can ignore very small things!
why is delta l considered to be soon small,what if we heat the substance to a high temperature
I imagine that most substances would begin to melt or degrade before the change in area from thermal expansion would become that significant.
hi, what if the area is rectangle and not square? i tried to get the final equation with no success...maybe some real experiment to just take it for granted!
You should be able to get a similar result using a rectangle instead of a square. A square just makes it easier.
Thank you !, It is much help for me ~~~
Your voice isn't quite the same here. Only slightly different but when you've watched a view videos easy to tell.
+Sena DuBois Maybe he recorded this in the morning. =PI have noticed that my voice sometimes sounds different in the mornings for some reason.

Thank you. Glad you like our videos.
why you make delta L is zero what you make if the tempereture becomes very high , delta L is not become what you say
Not delta L, but delta L squared. Since delta L is small, delta L squared is so small that we can ignore it.
We can't see to the board
