A sedative causes drowsiness (a sedative is a substance that produces drowsiness as its effect). We need a pair where the first item causes or produces the second. Anesthetic : numbness shows the same relationship: an anesthetic causes numbness, just as a sedative causes drowsiness.

Physics QUESTION #987

Question 5746

A transparent film of refractive index 2.0 is coated on a glass slab of refractive index 1.45. What is the minimum thickness of the film for maximum transmission of green light of wavelength 550 nm?

137.5 nm✔️
275 nm
94.8 nm
68.7 nm

Correct Answer Logic:

For maximum transmission (minimum reflection), destructive interference of reflected waves is needed. Since light goes from lower $n$ (air) to higher $n$ (film), and film $n >$ glass $n$, only one phase reversal occurs. Condition: $2\mu t = \lambda \Rightarrow t = \frac{\lambda}{2\mu} = \frac{550}{2\times2} = 137.5$ nm.

Mathematics QUESTION #4158

Question 5747

For the Laplace equation $u_{xx} + u_{yy} = 0$ on $0 < x < a$, $0 < y < b$ with $u(0,y) = u(a,y) = u(x,0) = 0$ and $u(x,b) = f(x)$, what is the general form of solution using separation of variables?

$u(x,y) = \sum_{n=1}^{\infty} B_n \sin(\frac{n\pi x}{a})\sinh(\frac{n\pi y}{a})$✔️
$u(x,y) = \sum_{n=1}^{\infty} B_n \cos(\frac{n\pi x}{a})\cosh(\frac{n\pi y}{a})$
$u(x,y) = \sum_{n=1}^{\infty} B_n \sin(\frac{n\pi x}{a})\cos(\frac{n\pi y}{b})$
$u(x,y) = \sum_{n=1}^{\infty} B_n e^{\frac{n\pi x}{a}}\sin(\frac{n\pi y}{b})$

Correct Answer Logic:

Boundary conditions $u(0,y) = u(a,y) = 0$ suggest $X(x) = \sin(\frac{n\pi x}{a})$. Condition $u(x,0) = 0$ gives $Y(0) = 0$, so $Y(y) = \sinh(\frac{n\pi y}{a})$.

Chemistry QUESTION #1088

Question 5749

For $\text{A(g)} \rightleftharpoons 2\text{B(g)}$, backward rate constant is 2500 times forward rate constant at 1000 K. $K_p$ at 1000 K is: (R = 0.0831 L atm mol$^{-1}$K$^{-1}$)

0.033✔️
0.021
83.1
$2.077\times10^5$

Correct Answer Logic:

$K_c = \frac{k_f}{k_b} = \frac{1}{2500} = 4\times10^{-4}$. For $\text{A}\rightleftharpoons 2\text{B}$: $\Delta n = 2-1=1$. $K_p = K_c(RT)^{\Delta n} = \frac{1}{2500}\times(0.0831\times1000)^1 = \frac{83.1}{2500} = 0.03324 \approx 0.033$.

Biology Zoology Botany QUESTION #1361

Question 5751

The phase of mitosis in which chromosomes align at the cell's equator is called:

Anaphase
Telophase
Metaphase✔️
Prophase

Correct Answer Logic:

During metaphase (the middle phase of mitosis), chromosomes become maximally condensed and are aligned along the cell's equatorial plane (metaphase plate) by spindle fibres attached to the centromeres (kinetochores). This alignment ensures accurate segregation of sister chromatids to the two daughter cells in the subsequent anaphase.

Casanova's Chinese Restaurant is a novel by:

Anthony Hope
Anthony Powell✔️
Anthony Trollope
Virginia Woolf

Physics QUESTION #999

Question 5753

The maximum percentage error in the measurement of density of a wire is: [mass $= (0.60\pm0.003)\ \text{g}$, radius $= (0.50\pm0.01)\ \text{cm}$, length $= (10.00\pm0.05)\ \text{cm}$]

8
5✔️

7

Correct Answer Logic:

Density $\rho = \frac{m}{\pi r^2 l}$. $\frac{\Delta\rho}{\rho} = \frac{\Delta m}{m} + 2\frac{\Delta r}{r} + \frac{\Delta l}{l} = \frac{0.003}{0.60}+2\times\frac{0.01}{0.50}+\frac{0.05}{10.00} = 0.005+0.04+0.005 = 0.05 = 5\%$.

Question 5754

In the context of IT-based library management, 'metadata harvesting' using the OAI-PMH (Open Archives Initiative Protocol for Metadata Harvesting) enables libraries to:

Physically collect rare items from other institutions
Automatically collect and aggregate metadata records from multiple distributed digital repositories into a single searchable interface✔️
Convert MARC records into RDA format
Manage staff attendance records

Correct Answer Logic:

OAI-PMH is a protocol that allows service providers to automatically harvest (collect) metadata records from multiple data providers (digital repositories, institutional repositories, open-access archives) and aggregate them into a unified searchable database — enabling federated discovery of distributed digital resources.

Question 5756

Depolarization of the postsynaptic membrane is caused by diffusion of which ion?

Calcium ions
Chloride ions
Potassium ions
Sodium ions✔️

Correct Answer Logic:

Depolarization occurs when Na⁺ enters the postsynaptic neuron (excitatory postsynaptic potential). Cl⁻ influx causes hyperpolarization (inhibitory). Ca²⁺ triggers neurotransmitter release, not directly depolarization.

Chemistry QUESTION #7353

Question 5758

Which of the following sets of quantum numbers represents an arrangement that is NOT allowed for an electron in an atom?

$n=3,\ \ell=2,\ m=-2,\ s=-\frac{1}{2}$
$n=4,\ \ell=0,\ m=0,\ s=-\frac{1}{2}$
$n=5,\ \ell=3,\ m=0,\ s=+\frac{1}{2}$
$n=3,\ \ell=2,\ m=-3,\ s=-\frac{1}{2}$✔️

Correct Answer Logic:

Rules for valid quantum numbers:

$n \geq 1$
$0 \leq \ell \leq n-1$
$-\ell \leq m \leq +\ell$

In option (4): $n=3, \ell=2$, so $m$ can range from $-2$ to $+2$. But $m = -3$ is outside this range, making it an invalid set. All other options satisfy the rules.

MBBS QUESTION #10354

Question 5759

In diabetic ketoacidosis, excessive hepatic ketone body production causes a high anion gap metabolic acidosis. Using the anion gap formula $AG = [Na^+] - ([Cl^-] + [HCO_3^-])$, which finding is expected?

An elevated anion gap, due to accumulation of unmeasured ketoacid anions (acetoacetate and beta-hydroxybutyrate)✔️
A normal anion gap accompanied by hyperchloremia
A decreased anion gap below the normal reference range
No change in anion gap despite the fall in blood pH

Correct Answer Logic:

Ketoacid anions (acetoacetate, beta-hydroxybutyrate) are not accounted for in the standard anion gap formula, so their accumulation raises the calculated gap — producing a characteristic high anion gap metabolic acidosis, distinguishing DKA from normal anion gap (hyperchloremic) causes of acidosis such as diarrhea or renal tubular acidosis.
