If I have a microbial sample that divides every 20 min. and they're asking me how much time is required for a single cell to grow into a population large enough to fill the volume of the Earth (1.09 x 10^21 m3), how can I find time when: r= 0.69 N0= 1 Nt= 1.10 x 10^39 They gave me this equation t= (ln(Nt) - ln(N0))/r but I'm not sure on what to do after that step (perhaps divide by 20? or multiply?). If anyone could help me figure it out, I'd really appreciate it.
If we set the integration of the growth rate function and set it equal certain limit then solve for r...but that is not how God works or does not work? God would improve on efficiency if all things to the max and let people have freewill of choosing their own happiness without violated other people individual pursuit of happiness
I understood here what I did not understand in school for three days. Thank you so much
You're a life saver! We are not gonna do calculations in the exam, but it's good to know the concept. Thank you!
I’m blessed with this video…THANKS!!!!
Khan! Love you channel! 😏❤️

8:36 😁😁 Maybe they are not in a mood to reproduce as much
Great
I m big fan of urr chnnel
If I have a microbial sample that divides every 20 min. and they're asking me how much time is required for a single cell to grow into a population large enough to fill the volume of the Earth (1.09 x 10^21 m3), how can I find time when:
r= 0.69
N0= 1
Nt= 1.10 x 10^39
They gave me this equation t= (ln(Nt) - ln(N0))/r but I'm not sure on what to do after that step (perhaps divide by 20? or multiply?). If anyone could help me figure it out, I'd really appreciate it.
Nice
So the 0.2 is an example right? How do I find the rmax if it isn't given to me?
Need to refer to prior video where R= Change in Birth - change in Death/ Population size
What if the population starts out higher than the carrying capacity?
Why do the multiply this factor of K-N/K can u pls explain it on the basis of mathematics
Yes, you want to know?
