Question

the cells of a bacteria double in every 30 minutes .a scientist begins with a single cell .how many cells will be there after
(a)12 hours (b) 24 hours
plz tell full solution ​

Answer 1

Answer:

▪︎Given -:

Time taken by the cells to doubled up = 30 mins

Scientist begins with = Single cell

▪︎To find -:

Hoe much cells there will be after :

(i) 12 hours

(ii) 24 hours

▪︎Concept -:

First , divide 12 hours and 24 hours with $\frac{30min}{60min}$ . Then which the number come just go doing it double till which the number has been before .

▪︎Solution -:

(i) 12 hours

First , divide:

$>>12÷\frac{30}{60}$

$>>12×\frac{2}{1}$

$>>24$

Now , go doing double 24 times :

1 double to 2 . Then , 4 and like this the answer will be 8388608 cells .

(ii) 24 hours

$>>24÷\frac{1}{2}$

$>>24×\frac{2}{1}$

$>>48$

Now , go doing double 48 times :

After doubling the answer will be 281474976710656 cells .

▪︎Extra information -:

To find velocity:

$Velocity =\frac{Displacement}{Time}$

To find Acceleration:

$Acceleration=\frac{Final\:velocity-Initial\:velocity}{Time}$

To find area of the triangle:

$At=\frac{Height×Base}{2}$
