The Memory Controller Chip (MCC) is a bridge between the CPU and the RAM. It manages the flow of data between these two critical components. The address bus then sends the LOCATION of the data from the CPU to the MCC, without sending the data itself.

Studies show that an 'authoritarian family' tends to produce an adolescent who is:

Dependent and obedient✔️
Self-reliant
Independent but reserved

Correct Answer Logic:

The colon correctly introduces the explanation (the ship's weight) for why it was hard to dislodge.

Physics QUESTION #7080

Question 7068

A pendulum using a uniform wire of area $A$ has a period $T$. Adding a mass $M$ to the bob changes the period to $T_M$. If $Y$ is the Young's modulus, then $\frac{1}{Y}$ is equal to:

$[(\frac{T_M}{T})^{2}-1]\frac{A}{Mg}$✔️
$[(\frac{T_M}{T})^{2}-1]\frac{Mg}{A}$
$[1-(\frac{T_M}{T})^{2}]\frac{A}{Mg}$
$[1-(\frac{T}{T_M})^{2}]\frac{A}{Mg}$

Correct Answer Logic:

The time period of a pendulum is $T = 2\pi\sqrt{\frac{L}{g}}$, so $L \propto T^2$.

Initial length: $L = kT^2$
New length: $L + \Delta L = k T_M^2$
Strain: $\frac{\Delta L}{L} = \frac{T_M^2 - T^2}{T^2} = (\frac{T_M}{T})^2 - 1$
From $Y = \frac{\text{Stress}}{\text{Strain}} = \frac{Mg/A}{\Delta L/L}$
Therefore, $\frac{1}{Y} = \frac{\Delta L/L}{Mg/A} = [(\frac{T_M}{T})^2 - 1]\frac{A}{Mg}$

Statistics QUESTION #1992

Question 7070

For a symmetric distribution, Bowley's coefficient of skewness is 0 and Pearson's coefficient $\beta_1 = \dfrac{\mu_3^2}{\mu_2^3}$ equals:

$1$
$0$✔️
$-1$
$3$

Correct Answer Logic:

For a perfectly symmetric distribution, the third central moment $\mu_3 = 0$ (since positive and negative deviations cancel symmetrically). Therefore $\beta_1 = \dfrac{\mu_3^2}{\mu_2^3} = \dfrac{0}{\mu_2^3} = 0$. Note: $\beta_1 = 0$ indicates zero skewness.

Psychology QUESTION #9910

Question 7071

All human senses evolved for the same primary purpose:

To increase our ability to enjoy the environment
To make us more aware of our feelings and internal states
To provide information that could improve communication
To help us survive✔️

Correct Answer Logic:

From an evolutionary perspective, sensory systems evolved because they enhanced survival — detecting predators, food, mates, and environmental hazards. Enjoyment and communication are secondary benefits of sensory capacity.

Mathematics QUESTION #6981

Question 7073

A bag has 4 red and 6 black balls. One ball is drawn, observed, and returned along with 2 more balls of the same colour. A second ball is then drawn. Find the probability that the second ball drawn is red.

$\dfrac{1}{5}$
$\dfrac{3}{4}$
$\dfrac{3}{10}$
$\dfrac{2}{5}$✔️

Correct Answer Logic:

Initially: 4 red, 6 black (10 total).

Case 1 — First ball is red (prob $= \frac{4}{10}$):
Bag becomes: 6 red, 6 black (12 total). $P(\text{red 2nd}) = \frac{6}{12} = \frac{1}{2}$.

Case 2 — First ball is black (prob $= \frac{6}{10}$):
Bag becomes: 4 red, 8 black (12 total). $P(\text{red 2nd}) = \frac{4}{12} = \frac{1}{3}$.

Total: $\dfrac{4}{10}\cdot\dfrac{1}{2}+\dfrac{6}{10}\cdot\dfrac{1}{3} = \dfrac{2}{10}+\dfrac{2}{10} = \dfrac{4}{10} = \dfrac{2}{5}$

Library Sciences QUESTION #1563

Question 7074

Which type of library circulation system uses barcodes or RFID tags on both library cards and items, and automates the charging and discharging process through an Integrated Library System (ILS)?

Browne system
Ledger system
Automated circulation system✔️
Dummy card system

Correct Answer Logic:

Automated circulation systems use barcodes or RFID technology on items and patron cards, linked to an Integrated Library System (ILS), to automatically record loans, returns, renewals, and holds — replacing manual systems like the Browne system or ledger-based methods.

Mathematics QUESTION #11179

Question 7075

Let $X = \{a,b,c\}$, $\tau = \{\emptyset,\{a\},\{b\},\{a,b\},X\}$. Then $X$ is:

$T_1$-space✔️
Regular space
$T_2$-space
Normal space

Correct Answer Logic:

Check $T_1$: in $T_1$, every singleton must be closed. $\{a\}$ is open, so $\{b,c\}$ is closed. $\{b\}$ is open, so $\{a,c\}$ is closed. But $\{c\}$: its complement $\{a,b\}\in\tau$ is open, so $\{c\}$ is closed. So singletons are closed → $T_1$ holds. Check $T_2$ (Hausdorff): for $a$ and $c$, we need disjoint open sets. The open sets containing $c$ are only $X$, and any open set containing $a$ is $\{a\}$ or $\{a,b\}$ or $X$ — none disjoint from $X$. Not $T_2$. So $X$ is $T_1$.

Chemistry QUESTION #5524

Question 7076

Match the following: Column I — (A) Allosteric effect, (B) Competitive inhibitor, (C) Receptor, (D) Poison; Column II — (P) Molecule binding to the active site, (Q) Molecule crucial for body communication, (R) Molecule binding to a site other than the active site, (S) Molecule binding covalently to the enzyme

$(A)\to(R);\ (B)\to(P);\ (C)\to(Q);\ (D)\to(S)$✔️
$(A)\to(P);\ (B)\to(R);\ (C)\to(Q);\ (D)\to(S)$
$(A)\to(R);\ (B)\to(P);\ (C)\to(S);\ (D)\to(Q)$
$(A)\to(P);\ (B)\to(R);\ (C)\to(S);\ (D)\to(Q)$

Correct Answer Logic:

Allosteric effect: A molecule binds to a site other than the active site, altering enzyme activity → (R). Competitive inhibitor: A molecule structurally similar to the substrate binds the active site → (P). Receptor: Molecules (like hormones/neurotransmitters) crucial for body communication bind receptors → (Q). Poison: Poisons like heavy metal ions bind enzymes covalently and permanently inactivate them → (S).

Islamic Studies QUESTION #8209

Question 7080

On his way back from the Battle of Tabook, the Holy Prophet (PBUH) ordered to demolish which mosque?

Quba
Zarrar✔️
Shuhada
Namra

Correct Answer Logic:

After returning from the Battle of Tabuk (9 AH), the Prophet (PBUH) ordered the demolition of Masjid al-Dirar (Mosque of Harm). This mosque was built by hypocrites in Medina with malicious intent—not for worship but to create division among Muslims and provide a base for enemy activities. The Quran revealed verses (9:107-108) exposing their hypocrisy. The mosque was demolished and burned, and the site was turned into a garbage dump to prevent its reconstruction.
