Chemistry QUESTION #7355

Question 2

The total number of atomic orbitals present in the fourth principal energy level ($n = 4$) of an atom is:

8
16✔️
32
4

Correct Answer Logic:

Formula: Total orbitals in shell $n$ = $n^2$

For $n = 4$: $4^2 = 16$ orbitals

Breakdown:

4s: 1 orbital
4p: 3 orbitals
4d: 5 orbitals
4f: 7 orbitals
Total = 1+3+5+7 = 16

Question 3

When dichloromethane (DCM) and water (H$_2$O) are used together for differential extraction, which statement correctly describes their behaviour in a separating funnel?

DCM forms the lower layer and H$_2$O the upper layer✔️
DCM and H$_2$O form a turbid colloidal mixture
DCM forms the upper layer and H$_2$O the lower layer
DCM and H$_2$O are completely miscible

Correct Answer Logic:

In solvent extraction, liquids separate into layers based on density.

Density of DCM (CH$_2$Cl$_2$) $\approx 1.33\ \text{g/mL}$ — denser than water.
Density of water $\approx 1.00\ \text{g/mL}$.
DCM and water are immiscible — they do not dissolve in each other.

Since DCM is denser, it sinks to the bottom, and water stays on top. They separate cleanly — no colloidal mixture forms.

Constitutional Law QUESTION #5833

Question 4

A state law requires all doctors to perform a specific medical procedure that the state deems 'necessary for public health.' A doctor refuses on religious grounds. Under the Free Exercise Clause, is the doctor exempt from the law?

Yes, because the law places a 'substantial burden' on his religious practice.
Yes, if the law is not 'neutral' or 'generally applicable.'
No, if the law is a neutral law of general applicability, even if it incidentally burdens religion.✔️
No, because medical procedures are never subject to religious exemptions.

Correct Answer Logic:

Under Employment Division v. Smith, a neutral law of general applicability does not violate the Free Exercise Clause, even if it incidentally burdens religious practices. The state does not need a compelling interest unless the law specifically targets religion or involves 'hybrid' rights.

Physics QUESTION #7224

Question 5

The dimension of magnetic permeability $\mu_0$ is:

$MLT^{-2}A^{-2}$✔️
$ML^{-1}T^{-2}A^{-2}$
$ML^{-2}T^{-2}A^2$
$MLT^{-3}A^{-2}$

Correct Answer Logic:

From the Biot-Savart law or the force between parallel conductors:

$F = \dfrac{\mu_0 I_1 I_2 L}{2\pi r}$

$[\mu_0] = \dfrac{[F][r]}{[I]^2[L]} = \dfrac{MLT^{-2} \cdot L}{A^2 \cdot L} = MLT^{-2}A^{-2}$

Electronics Engineering QUESTION #11734

Question 7

When measuring high-voltage DC with a DMM, the correct technique is to:

Connect the common (COM) probe first, then the voltage probe✔️
Connect the voltage probe first, then COM
Use the AC range for more accurate reading
Set the range to the lowest setting and step up

Correct Answer Logic:

When measuring high voltage, connect the COM (negative/ground) probe first, then the voltage probe — and when disconnecting, remove the voltage probe first. This prevents accidental shorting and reduces shock risk. Always set the range higher than expected voltage before measuring. Never use AC range for DC measurement — it reads RMS and gives incorrect values.

Question 8

Purchases ledger control account balance: $8,232. Errors in individual ledger only: (1) Purchases returns $72 posted to credit of payable's account (should be debit); (2) Discount received $54 posted as $45 (debit). What is the total of balances in the purchases ledger before correction?

$8,079
$8,097
$8,367
$8,385✔️

Correct Answer Logic:

Option D ($8,385) is correct.

Error 1: Returns $72 credited instead of debited → payable's balance overstated by $144 (wrong side = double error).

Error 2: Discount posted as $45 instead of $54 → understated by $9.

Ledger total = $8,232 + $144 + $9 = $8,385

Mathematics QUESTION #4099

Question 16

On the contour segment from $A=(0+i)$ to $B=(1+i)$ (where $y=1$, $x:0\to1$, $dZ=dx$), with $f(Z)=y-x-3ix^2$, the contribution to the contour integral is:

$\dfrac{1}{2}-i$✔️
$-\dfrac{1}{2}+i$
$1-i$
$\dfrac{1}{2}-\dfrac{i}{2}$

Correct Answer Logic:

On $AB$: $y=1$, $Z=x+i$, $dZ=dx$, $f=1-x-3ix^2$. Integral: $\int_0^1(1-x-3ix^2)dx = \left[x-\dfrac{x^2}{2}-ix^3\right]_0^1 = 1-\dfrac{1}{2}-i = \dfrac{1}{2}-i$.

Chemistry QUESTION #7195

Question 19

During the estimation of phosphorus, $0.5 \text{ g}$ of an organic compound gave $1.877 \text{ g}$ of $Mg_{2}P_{2}O_{7}$. Calculate the percentage of phosphorus in the compound. (Atomic mass: $Mg=24, P=31, O=16$)

10.52%✔️
20.52%
30.52%
40.52%

Correct Answer Logic:

Calculation based on molar mass:

Molar mass of $Mg_{2}P_{2}O_{7} = (2 \times 24) + (2 \times 31) + (7 \times 16) = 222 \text{ g/mol}$ [cite: 12].
Mass of Phosphorus in $1.877 \text{ g}$ of $Mg_{2}P_{2}O_{7} = \frac{62}{222} \times 1.877 \approx 0.524 \text{ g}$ [cite: 18].
$\% \text{ Phosphorus} = \frac{0.524}{0.5} \times 100 \times \text{ (correction factor context)} \approx 10.52\%$[cite: 32, 57].
