Ye ques 39 ka answer kaise 0.34 ho gya Hume to smjh nai arha....kisi ko arha h to btaye.
Pehle to 0.15 tha.
Even I got this wrong. Can anyone explain the logic behind this question, how to calculate growth rate from OD?
We knw tht -dx/dt= ux..we hd to fnd the u=?...though the OD equal to the concn of micro organisim...its mean OD value = x...do the integration...we got ln(x) wid limit 0.3 to 0.6 and time t wid limit 2 to 4
Now , ln( 0.6) - ln (0.3) = u (4-2)
-0.51 - (-1.2) = u×2
0.70 = u ×2
u =0.35 ( answer)
