2.5 half life 1st half life 500/2 =250 g 2nd half life 250/2= 125.0g 3rd half life 125.0/2= 62.50g 4th half life 62.50/2 = 31.25g therefore it has reach the given have life kept in th cupboard we say: t1/2 =4 so after 10 day = 10/4 = 2.5 half life. thanks if u see somtin like this , it the shortest cut with ur time.
The teaching was very helpful 🙂 Solving for the Answer Starting with 500g. After The 1st half life we got 250g The 2nd half life we got 125g The 3rd half life we got 62.5g The 4th half life we got 31.25g we know now that it takes four half life to decay to 31.25g 4(t1/2)=10 Days 10/4=2.5days I pray I'm correct🙏👍
Thank you very much for this . God will continue to bless and protect you. My answer is 2.5 days. Do they ask questions like this in physics also ok radioactivity
To me if you cross multiple you won't get it all you have to do is this Ni/Nf=2n which is 500/31.25 it will give you 16 then you ask yourself how many times will 2 go into 16 the answer will be 4 , which is 2×2×2×2=16. Then it becomes 2⁴ then you divide your time which is 10 by 4 . 10/4 =2.5✅
Wow,sir I love your teaching absolutely the best👍👍👍,just for the first time watching it
2.5 half life
1st half life 500/2 =250 g
2nd half life 250/2= 125.0g
3rd half life 125.0/2= 62.50g
4th half life 62.50/2 = 31.25g
therefore it has reach the given have life kept in th cupboard
we say: t1/2 =4
so after 10 day = 10/4 = 2.5 half life. thanks if u see somtin like this , it the shortest cut with ur time.
Please, let's connect,help a friend.. I couldn't solve this right... Anyone who can help, please reply
Use ur knowledge of indices 2raised to the power of 4 gives 16 therefore 4=10/t^1/2 thalf equals 10/4
@@case.point.com.07 well,am trying to understand.....is this for her short cut,of from the nurse Bright's formula
Thanks now I understand
The teaching was very helpful 🙂
Solving for the Answer
Starting with 500g.
After The 1st half life we got 250g
The 2nd half life we got 125g The 3rd half life we got 62.5g The 4th half life we got 31.25g we know now that it takes four half life to decay to 31.25g 4(t1/2)=10 Days 10/4=2.5days
I pray I'm correct🙏👍
Sir thank you for aiding me in my jamb preparation.......... the answer is 2.5 days.
Very correct
I love ❤️ it
Thank you very much for this . God will continue to bless and protect you. My answer is 2.5 days.
Do they ask questions like this in physics also ok radioactivity
Very Correct ♥️
Amen
Yes it's Similar in Physics also
Pls how did u solve it
Ni/Nf=2n
500/31.25=2n
16=2n
2*4=2n
n=4
n=to/t1/2
to/t1/2=4
t1/2=to/4
t1/2=10/4
t1/2=2.5ANS
Pls explain where u got 2*4
Nice one
Thank you very much sir may God continue to bless you more and more in Jesus name amen 💕💕💕💕
Amen
Keep sharing with friends
I'm getting 2.5 hope is correct sir
Please how did you get 2.5
Nice class
Please sir how did you do 2'2.462
Sir i had 0.625...How did they get 2.5....i made half-life subject o
I wonder oo,my sister ,I don solve tire....ahbii my brain naa only water full amm😢😢😢
Sir please how can we solve 2*2.462 without calculator,cos jamb calculator does not have raise to Power 😢
Sir, please you said in part one that the unit for the half-life is in min or s or hrs then why didn't you change this one to either hrs
Sir what if we are given this type of question in jamb, how can we solve it without calculator
Thank you very much sir
2.5 days
Hw Can jamb calculator do 2 raise to power 2.462
It simply means 2.462×2.462
I got 2.5 is it correct
Question 2 can't be a JAMB question, right? Cause there is no way we are gonna be able to solve that without a Scientific Calculator
Hey sir, am a student from G.brain lecture at oghede
Nice..❤️❤️
Sir pls I don't know how to solve this one
@@NurseBrighthow do i solve it pls
@@PrincessSunday-w5fhow do i solve it
The answer to that question is......t1/2=2.5yr-1
2.5days
Very correct
Please how do they get 2.5?
2.64
The half-life is 2.5days
Very Correct ❤️
Please 🥺 how did you solve it
Sir please can you do the correction
Pls I'm not getting the right answer
I too
I got 3...
How did you guys solve it
2.5
very Correct
Sir I converted my days to hrs and I got 0.0333
The answer is 2.5days as the half life
2.5g
Half life is 2.5days
Very correct
I got 1.25day
I got 2.5
Very correct
Halflife= 2.5 days
very Correct
Sir I got 2.5 days
I got 1.5😢
Please some body should solve it
