Question 2

The solubility of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid. This statement is based upon:

Raoult's law
Henry's law✔️
Kohlrausch's law

Question 5

The output Y of the given logic circuit (NAND-NAND implementation) is similar to output of a ________ gate.

OR
NOR
AND✔️
NAND

Correct Answer Logic:

The circuit shows: A and B fed into a NAND gate, A also fed separately, and outputs combined into another NAND. Using Boolean algebra: NAND of two NANDs of (A,B) and (A,A) simplifies to AND. The output $Y = \overline{\bar{A}+\overline{AB}} = A\cdot B$ (AND gate).

Question 16

Most crustaceans have blue blood due to the presence of:

Haemoglobin
Erythrocruorin
Haemocyanin✔️
None of these

Correct Answer Logic:

Haemocyanin (haemocyanine) is a copper-containing respiratory pigment found in the blood (haemolymph) of most crustaceans (crabs, lobsters, shrimps) and molluscs. It appears blue when oxygenated because the copper atoms bind oxygen and cause the blue coloration, similar to how iron in haemoglobin gives blood its red color. Erythrocruorin is an iron-based pigment in some worms.

Mathematics QUESTION #1317

Question 18

Assuming $u(x,y)=X(x)Y(y)$ in $u_{xx}+u_{yy}=0$, the separated ODEs are:

$X''-\lambda X=0$ and $Y''+\lambda Y=0$
$X''+\lambda X=0$ and $Y''-\lambda Y=0$✔️
$X''+\lambda X=0$ and $Y''+\lambda Y=0$
$X''-\lambda X=0$ and $Y''-\lambda Y=0$

Correct Answer Logic:

Substituting: $X''Y+XY''=0\Rightarrow\dfrac{X''}{X}=-\dfrac{Y''}{Y}=\lambda$. For the $x$-direction with $u(0,y)=u(a,y)=0$, we need oscillatory solutions: $X''+\lambda X=0$ with $\lambda>0$. Then $Y''-\lambda Y=0$ gives exponential/hyperbolic solutions.
