There is an error of 10 in the readings of count rate because as you can see the graph becomes flat and constant at 2.5 boxes above the x axis, so we consider an error of 2.5 boxes on the count rate axis which is an error of 10 in the count rate so 90 is actually 80. Hope this clears the confusion.
You are just saving life. Thank you enormously, Amazing Job!
Miss plzz upload videos on communication asap, these vids have helped me a ton!!! thankzźz :DD
Thank you so much for the detailed explanation!
Thanks a lot for this recording❤❤❤
can we calculate the half-life by using exponential equation and then dividing it by the number of boxes of background radiation
Beautiful explanation. Thanks
Thank you so much
This was really helpful
Thank you so much miss!
i dont understand ptii, please help. if we are going to take values of 90 then why are we considering 80?
