1✔️
2
3
4

Correct Answer Logic:

Boron has atomic number 5. Its electronic configuration is $1s^2\ 2s^2\ 2p^1$. The single electron in the $2p$ orbital is unpaired, so there is $\mathbf{1}$ unpaired electron.

Reading and Writing (Module-1) QUESTION #5399

Question 4229

The mimosa tree evolved in East Asia, where the beetle Bruchidius terrenus preys on its seeds. In 1785, mimosa trees were introduced to North America, far from any B. terrenus. But evolutionary links between predators and their prey can persist across centuries and continents. Around 2001, B. terrenus was introduced in southeastern North America near where botanist Shu-Mei Chang and colleagues had been monitoring mimosa trees. Within a year, 93 percent of the trees had been attacked by the beetles. Which choice best describes the function of the third sentence in the overall structure of the text?

It states the hypothesis that Chang and colleagues had set out to investigate using mimosa trees and B. terrenus.
It presents a generalization that is exemplified by the discussion of the mimosa trees and B. terrenus.✔️
It offers an alternative explanation for the findings of Chang and colleagues.
It provides context that clarifies why the species mentioned spread to new locations.

Correct Answer Logic:

The third sentence generalizes that predator-prey links persist across time and distance, which is then exemplified by the beetles attacking mimosa trees over 200 years after their separation.

Verbal Reasoning QUESTION #8158

Question 4230

Let $X$ be the set of all integers $n$ satisfying $2 \leq |n| \leq 5$. Compare:

Quantity A: The absolute value of the greatest integer in $X$

Quantity B: The absolute value of the least integer in $X$

Quantity A is greater
Quantity B is greater
The two quantities are equal✔️
The relationship cannot be determined from the information given

Correct Answer Logic:

The set $X$ consists of all integers $n$ with $2 \leq |n| \leq 5$.

These are: $-5, -4, -3, -2, 2, 3, 4, 5$.

The greatest integer in $X$ is $5$, and $|5| = 5$.

The least integer in $X$ is $-5$, and $|-5| = 5$.

Both absolute values equal $5$, so the two quantities are equal.

Mathematics QUESTION #974

Question 4234

Suppose that the number of terms in an A.P. is $2k,\ k\in\mathbb{N}$. If the sum of all odd terms of the A.P. is 40, the sum of all even terms is 55, and the last term exceeds the first term by 27, then $k$ is equal to:

6
5✔️
8
4

Correct Answer Logic:

Let first term $=a$, common difference $=d$, number of terms $=2k$. Sum of odd-positioned terms $=k\left(a+\frac{(2k-1)d}{2}\cdot\text{...}\right)=40$, even terms $=55$. Difference: $kd=15$. Last $-$ first $=(2k-1)d=27$. From $kd=15$ and $(2k-1)d=27$: dividing gives $2k-1=\frac{27k}{15} \Rightarrow k=5$.

Physics QUESTION #5586

Question 4235

A room is supplied with electricity at 120 V. The lead wires have a total resistance of $6\,\Omega$. A 60 W bulb is already running. What is the decrease in voltage across the bulb when a 240 W heater is switched on in parallel with the bulb?

Zero Volt
2.9 Volt
13.3 Volt
10.04 Volt✔️

Correct Answer Logic:

Resistance of the bulb: $R_b = \frac{V^2}{P} = \frac{(120)^2}{60} = 240\,\Omega$

Before heater is switched on: Current $= \frac{120}{240+6} = \frac{120}{246}\,\text{A}$. Voltage across bulb $= \frac{120 \times 240}{246} \approx 116.9\,\text{V}$.

Resistance of heater: $R_h = \frac{(120)^2}{240} = 60\,\Omega$. Parallel combination: $R_p = \frac{240 \times 60}{300} = 48\,\Omega$.

After heater is switched on: Voltage across combination $= \frac{120 \times 48}{48+6} = \frac{5760}{54} \approx 106.67\,\text{V}$.

Decrease $= 116.9 - 106.67 \approx 10.04\,\text{V}$. Answer: D.

Chemistry QUESTION #7176

Question 4239

In a $10 \text{ m}^{3}$ container at $1000 \text{ K}$, a mixture of $0.5$ moles of gas A and $x$ moles of gas B exerts a total pressure of $200 \text{ Pa}$. If $R$ is the gas constant, find the value of $x$.

$\frac{2R}{4+R}$
$\frac{2R}{4-R}$
$\frac{4+R}{2R}$
$\frac{4-R}{2R}$✔️

Correct Answer Logic:

Using the Ideal Gas Equation $PV = nRT$:

Total moles $n = 0.5 + x$
$200 \times 10 = (0.5 + x) \times R \times 1000$
$2000 = (0.5 + x)1000R$
$2 = (0.5 + x)R$
$2/R = 0.5 + x$
$x = \frac{2}{R} - \frac{1}{2} = \frac{4-R}{2R}$

Chemistry QUESTION #7157

Question 4240

The significant reducing ability of hypophosphorous acid ($H_{3}PO_{2}$) is primarily due to the presence of:

Two $P-OH$ bonds
One $P-H$ bond
Two $P-H$ bonds✔️
One $P-OH$ bond

Correct Answer Logic:

The reducing character of oxoacids of phosphorus depends on the number of $P-H$ bonds present. In $H_{3}PO_{2}$ (Hypophosphorous acid), the phosphorus atom is bonded to two hydrogen atoms directly ($2 \times P-H$ bonds) and one hydroxyl group ($1 \times P-OH$ bond). These $P-H$ bonds are responsible for its strong reducing property.
