Constant throughout the season
Low at initial stage → increases during crop development → peaks at mid-season → declines at late season (senescence/maturation)✔️
High at initial stage → decreases linearly to harvest
Peaks at germination then remains constant through grain fill

Correct Answer Logic:

In FAO-56 methodology, $K_c$ follows a characteristic curve: $K_{c,ini}$ (low, sparse cover) → $K_{c,mid}$ (peak, full canopy, maximum ET) → $K_{c,end}$ (lower, senescence, stomatal closure). For wheat: $K_{c,ini} \approx 0.3$, $K_{c,mid} \approx 1.15$, $K_{c,end} \approx 0.25–0.4$. This drives irrigation scheduling calculations.

Question 6105

The isoelectric point of casein, at which it precipitates from milk, is approximately:

$\text{pH}\; 4.0$
$\text{pH}\; 4.6$✔️
$\text{pH}\; 5.2$
$\text{pH}\; 6.6$

Correct Answer Logic:

Casein precipitates at its isoelectric point of $\text{pH}\; 4.6$. This principle is used in acid coagulation of milk for cheese and paneer making and explains why acidification of milk causes curd formation.

Mechanical Engineering QUESTION #2453

Question 6110

The general solution for forced damped vibration $x=x_1+x_2$ consists of:

Only the steady-state component $x_2=B_2\sin(pt-\phi)$
Transient free-damped oscillation $x_1=B_1e^{-\alpha t}\sin(\omega_d t+\psi)$ PLUS steady-state harmonic $x_2=B_2\sin(pt-\phi)$✔️
Only the transient component that decays to zero
A constant DC offset plus a harmonic

Correct Answer Logic:

The complete solution is $x=x_1+x_2$: the transient part $x_1=B_1e^{-\alpha t}\sin(\omega_d t+\psi)$ decays with time; the steady-state part $x_2=B_2\sin(pt-\phi)$ persists indefinitely.

Question 6113

If $x < 5$, then $x + 3$:

$< 8$✔️
$> 8$
$= 8$
$\geq 8$

Correct Answer Logic:

Adding same value to both sides preserves inequality. $x < 5 \Rightarrow x + 3 < 5 + 3 \Rightarrow x + 3 < 8$

Question 6117

Solve for $x$: $3x - 7 = 2x + 5$

10
12✔️
14
15

Correct Answer Logic:

$3x - 7 = 2x + 5$. Subtract $2x$ from both sides: $x - 7 = 5$. Add 7: $x = 12$.

Hypotonic urine with decreased volume
Hypotonic urine with increased volume
Hypertonic urine with decreased volume✔️
Hypertonic urine with increased volume

Correct Answer Logic:

ADH increases water reabsorption in the collecting ducts, resulting in concentrated (hypertonic) urine with decreased volume.
