Someone asked me, what is more clear then mirror...
I turned and replied, my concept after watching physics wallah videos...
Logic 😶
Sahi kaha na bro
@@hiteshgupta7684 ekdam bhai
Kya baat hai 😅👌👌
Iss comment ko itna like kardo ki sir ek baari ko dekh kar hass de 😊😊
In the first question, we can also use the fact that 10% nuclei decayed in 1 second, so in the next second 10% of the remaining nuclei will decay. So nuclei remaining after 2 seconds = 90 - (10% of 90) = 81 nuclei.
Thank you for this trick❤
Thankyou ❤
Yes bro
I was also used it
Thanks sir/ma'am!
This question was taken from DC Pandey
And you are explaining the answer from DC pandey
25:27 λ in terms of time: reciprocal of time during which 63.2% nuclei of initial amount has been degraded
t½(half life) 31:08
Different units of activity 58:00
Mean life 1:06:07
Studying nuclear physics after my 1st attempt, I had left this chapter literally from modern phy but after watching the video of sir, this chapter has become crystal clear now. Tqsm sir🙏🤗

Sir, aapki wajah se maine 1st numerical 39:05 ko khud apne tarike se kiya. Aapne motivate kiya ki khud se karo maine kra.
My way of doing this numerical ☺️☺️😎😎
At t=1sec
N=90, No =100
N=No e^-lambda t
90 = 100 e^-lamda
e^-lambda = 9/10
1/e^lamda = 9/10
e^lamda = 10/9
Now,
At t=2sec
N=?, No=100
N=No e^-2lambda
N = 100* 1/e^(lamda)^2
N= 100*1/(10/9)^2
N= 81*100/100
N=81
Sir, maine apki numerical solve kaise kre vo video dekhi thi

Uski vajah se main ye kr paya.
