Question 2622

The molar solubility ($s$) of zirconium phosphate with formula $(\text{Zr}^{4+})_3(\text{PO}_4^{3-})_4$ is given by the relation:

$\left(\dfrac{K_{sp}}{9612}\right)^{1/3}$
$\left(\dfrac{K_{sp}}{6912}\right)^{1/7}$✔️
$\left(\dfrac{K_{sp}}{8435}\right)^{1/7}$
$\left(\dfrac{K_{sp}}{5348}\right)^{1/6}$

Correct Answer Logic:

Dissolution: $\text{Zr}_3(\text{PO}_4)_4 \rightleftharpoons 3\text{Zr}^{4+} + 4\text{PO}_4^{3-}$. If solubility $= s$: $[\text{Zr}^{4+}]=3s$, $[\text{PO}_4^{3-}]=4s$. $K_{sp} = (3s)^3(4s)^4 = 27s^3 \cdot 256s^4 = 6912\,s^7$. So $s = \left(\dfrac{K_{sp}}{6912}\right)^{1/7}$.

Question 2623

In cost-benefit analysis, if Benefit-Cost Ratio (BCR) is 0.85, the project should be:

Immediately approved
Rejected✔️
Modified and reanalyzed
Implemented with subsidies

Correct Answer Logic:

BCR = $\frac{\text{PV of Benefits}}{\text{PV of Costs}}$ < 1.0 indicates costs exceed benefits, making the project economically unviable from a welfare perspective. Projects should only proceed if BCR ≥ 1.0, meaning benefits justify costs.

Physics QUESTION #1163

Question 2625

Fermi-Dirac statistics cannot be applied to:

Electrons
Photons✔️
Fermions
Proton

Correct Answer Logic:

Fermi-Dirac statistics applies to fermions — particles with half-integer spin ($\frac{1}{2}, \frac{3}{2}, \ldots$) that obey the Pauli exclusion principle. Electrons, protons, and neutrons are fermions. Photons are bosons (integer spin = 1) and obey Bose-Einstein statistics, not Fermi-Dirac.

Civil Procedure QUESTION #3697

Question 2626

A plaintiff sues a defendant in federal court. After the plaintiff rests at trial, the defendant moves for JMOL under Rule 50(a). The judge denies the motion. The defendant then presents evidence and rests. The jury returns a verdict for the plaintiff. The defendant does NOT file a renewed JMOL within 28 days. Can the defendant challenge the sufficiency of the evidence on appeal?

Yes, because the Rule 50(a) motion preserved the issue.
No, a post-verdict motion under Rule 50(b) is required to preserve a challenge to the sufficiency of the evidence on appeal.✔️
Yes, under the plain error doctrine.
No, unless the judge specifically invited an appeal.

Correct Answer Logic:

According to the Supreme Court in Unitherm Food Systems, Inc. v. Swift-Eckrich, Inc., a party's failure to file a Rule 50(b) motion post-verdict precludes an appellate court from reviewing the sufficiency of the evidence.

Question 2627

Which group of organisms is known for having chloroplasts in every cell?

Fungi
Algae✔️
Bryophytes
Lichens

Correct Answer Logic:

Algae contain chloroplasts in every photosynthetic cell of their thallus. Algal chloroplasts come in diverse shapes (cup-shaped, ribbon-like, stellate) and contain photosynthetic pigments. Fungi have no chloroplasts at all (they are heterotrophs). Bryophytes have chloroplasts in their green cells but not every cell (e.g., rhizoids lack them). Lichens are fungal-algal symbioses.

Electrical Engineering QUESTION #2177

Question 2637

A three-phase induction motor runs at $1440\,\text{rpm}$ on a $50\,\text{Hz}$ supply. The number of poles and percent slip are respectively:

4 poles, $4\%$✔️
6 poles, $4\%$
4 poles, $6\%$
8 poles, $4\%$

Correct Answer Logic:

Synchronous speed for $P = 4$: $N_s = \frac{120\times50}{4} = 1500\,\text{rpm}$. Slip $s = \frac{1500-1440}{1500}\times100 = 4\%$. For $P=6$: $N_s=1000\,\text{rpm}$, which would give negative slip — physically impossible.
