hello sir... I tried finding ur lectures on electric power and heating effects of electricity... could not find them... can u pls do a few lectures on power??
Lol I find this funny. Would you happen to know why is a kg a liter of water exactly at 39.2ºF? Why is this a magic number for a kg?
That is the temperature at which water is the most dense. Since they had to pick a particular density and temperature, they picked that one.
