Civil Procedure QUESTION #3699

Question 2762

A plaintiff (State A) sues a defendant (State B) in federal court in State A for $\text{\$100,000}$. The defendant impleads a third-party (State B) for indemnity. The third-party then files a counterclaim against the original plaintiff (State A) for $\text{\$10,000}$ arising from the same transaction. Does the court have jurisdiction over the third-party's counterclaim?

No, because the amount is under $\text{\$75,000}$.
No, because 1367(b) bars it.
Yes, because 1367(b) only restricts claims by 'plaintiffs' in diversity cases, not claims by other parties.✔️
Yes, but only if the plaintiff consents.

Correct Answer Logic:

28 U.S.C. $\S 1367(b)$ restricts supplemental jurisdiction for claims 'by plaintiffs' against persons made parties under certain rules (14, 19, 20, 24). It does not restrict claims by defendants or third-party defendants against the original plaintiff.

Chemistry QUESTION #5537

Question 2763

If the activation energy of a reaction is $80.9\ \text{kJ mol}^{-1}$, the fraction of molecules at 700 K having sufficient energy to react is $e^{-x}$. Find the value of $x$ (nearest integer). [Use $R = 8.31\ \text{J K}^{-1}\text{mol}^{-1}$]

14✔️
13
12
11

Correct Answer Logic:

The fraction of molecules with energy $\geq E_a$ is given by $f = e^{-E_a/RT}$. So $x = \frac{E_a}{RT} = \frac{80900}{8.31\times700} = \frac{80900}{5817} \approx 13.9 \approx 14$.

Chemistry QUESTION #1014

Question 2764

Statement (I): An element in the extreme left of the periodic table forms acidic oxides. Statement (II): Acid is formed during the reaction between water and the oxide of a reactive element present in the extreme right of the periodic table.

Statement I is true but Statement II is false
Both Statement I and Statement II are true
Both Statement I and Statement II are false
Statement I is false but Statement II is true✔️

Correct Answer Logic:

Statement I is false — elements on the extreme left (alkali metals) form basic oxides (e.g., $\text{Na}_2\text{O} + \text{H}_2\text{O} \to \text{NaOH}$). Statement II is true — elements on the extreme right (halogens) form acidic oxides, e.g., $\text{Cl}_2\text{O} + \text{H}_2\text{O} \to \text{HClO}$.

Statistics QUESTION #1979

Question 2765

A box contains 4 bad and 6 good tubes. Two tubes are drawn at random. Given that one tested tube is good, the probability that the other is also good using the conditional probability approach is:

$\dfrac{1}{3}$
$\dfrac{5}{9}$
$\dfrac{5}{14}$
$\dfrac{5}{13}$✔️

Correct Answer Logic:

Let A = both good, B = at least one good. $P(A) = \binom{6}{2}/\binom{10}{2} = 15/45 = 1/3$. $P(B) = 1 - P(\text{both bad}) = 1 - \binom{4}{2}/\binom{10}{2} = 1 - 6/45 = 39/45$. But the condition is one specific tube tested is good: $P(\text{other good}|\text{one is good}) = \frac{5}{9}$ using hypergeometric reasoning on remaining 9 tubes (5 good, 4 bad). Answer is $\dfrac{5}{9}$.

Agronomy QUESTION #2059

Question 2766

Evapotranspiration (ET) differs from evaporation (E) in that:

ET occurs only from open water surfaces while E includes transpiration
ET is the combined water loss from soil evaporation and plant transpiration from a cropped surface, while E refers only to physical vaporization from soil or water surfaces without plant involvement✔️
ET can be measured directly with a rain gauge while E requires a lysimeter
ET decreases with increasing leaf area index while E increases

Correct Answer Logic:

Evapotranspiration combines two processes: evaporation (physical — from soil, water surfaces) and transpiration (biological — water movement through plant tissues and vapor loss from stomata). As crop canopy develops, the E component decreases (shading reduces soil evaporation) while T increases, but total ET is governed by available energy and atmospheric demand.

Basic Mathematics QUESTION #2880

Question 2767

If $A:B = 2:3$ and $B:C = 4:5$, find $A:B:C$.

2:3:5
8:12:15✔️
4:6:10
2:4:5

Correct Answer Logic:

Multiply ratios to align B: $A:B = 8:12$ and $B:C = 12:15$. Thus $8:12:15$.

Electrical Engineering QUESTION #2170

Question 2768

A lossy transmission line has $R = 0.1\,\Omega/\text{m}$, $G = 0.01\,\text{S/m}$, $L = 1\,\mu\text{H/m}$, $C = 1\,\text{nF/m}$. Is the Heaviside distortionless condition $RC = GL$ satisfied?

No; $RC = 10^{-10}$ but $GL = 10^{-8}$✔️
Yes; both equal $10^{-9}$
Yes; both equal $10^{-8}$
Cannot be determined without frequency

Correct Answer Logic:

$RC = 0.1 \times 10^{-9} = 10^{-10}$. $GL = 0.01 \times 10^{-6} = 10^{-8}$. Since $RC \ne GL$, the distortionless condition is NOT satisfied.

Agronomy QUESTION #2047

Question 2775

The Economic Threshold Level (ETL) in crop pest management is defined as:

The pest density at which the crop begins to show visible damage symptoms
The pest population density at which control measures must be initiated to prevent the pest from reaching the Economic Injury Level (EIL) — accounting for the time needed for control measures to take effect✔️
The maximum pest density a crop can tolerate without any yield loss
The point at which 50% of the crop stand is destroyed by the pest

Correct Answer Logic:

ETL (action threshold) is always set BELOW the Economic Injury Level (EIL) — the pest density at which economic damage equals cost of control. The ETL triggers action while the pest population is still rising, allowing time for control measures to prevent the EIL from being reached. ETL < EIL is a fundamental IPM concept.

Mathematics QUESTION #981

Question 2779

Let $E:\dfrac{x^2}{a^2}+\dfrac{y^2}{b^2}=1,\ a>b$ and $H:\dfrac{x^2}{A^2}-\dfrac{y^2}{B^2}=1$. Let the distance between the foci of $E$ and the foci of $H$ be $2\sqrt{3}$. If $a-A=2$ and the ratio of eccentricities of $E$ and $H$ is $\dfrac{1}{3}$, then the sum of the lengths of their latus rectums is equal to:

10
9
8✔️
7

Correct Answer Logic:

Let $e_E=e$ and $e_H=3e$. Focal distances: $2ae=2\sqrt{3}\Rightarrow ae=\sqrt{3}$ and $2Ae_H=2\sqrt{3}\Rightarrow 3Ae=\sqrt{3}\Rightarrow Ae=\frac{1}{\sqrt{3}}$. Then $\frac{a}{A}=3$ and $a-A=2\Rightarrow A=1, a=3$. So $e=\frac{\sqrt{3}}{3}=\frac{1}{\sqrt{3}}$, $b^2=a^2(1-e^2)=9\cdot\frac{2}{3}=6$. For $H$: $e_H=\sqrt{3}$, $B^2=A^2(e_H^2-1)=2$. Sum of latus rectums $=\frac{2b^2}{a}+\frac{2B^2}{A}=\frac{12}{3}+\frac{4}{1}=4+4=8$.
