MCQs Section QUESTION #4908

A President entering the final two years of a second term _____ carry out a legislative program.

likely to be at a severe disadvantage and is often unable to✔️
likely severely disadvantaged and often unable to
liable to be severely disadvantaged and cannot often
liable that he or she is at a severe disadvantage and cannot often

Correct Answer Logic:

Likely to be' is the correct idiom and 'is often unable to' provides the needed parallel auxiliary structure. 'Liable' in options C and D implies legal responsibility, which is the wrong meaning here. Option E (not shown) is structurally incoherent. Option B omits a linking verb, making 'likely' a dangling adjective.

Physics QUESTION #1063

Question 991

Parallel plate capacitor, plates separated by $d$. Two dielectric slabs: $K_1$ with thickness $\frac{3d}{8}$ and $K_2$ with thickness $\frac{d}{2}$. Capacitance becomes twice that of air capacitor. If $K_1=1.25K_2$, value of $K_1$ is:

1.60
1.33
2.66✔️
2.33

Correct Answer Logic:

Air gap remaining: $d - \frac{3d}{8} - \frac{d}{2} = \frac{d}{8}$. Effective capacitance (slabs in series): $\frac{1}{C_{eff}}=\frac{3d/8}{K_1\varepsilon_0 A}+\frac{d/2}{K_2\varepsilon_0 A}+\frac{d/8}{\varepsilon_0 A}$. Setting $C_{eff}=2C_0=\frac{2\varepsilon_0 A}{d}$: $\frac{d}{2\varepsilon_0 A}=\frac{3d/8}{K_1\varepsilon_0 A}+\frac{d/2}{K_2\varepsilon_0 A}+\frac{d/8}{\varepsilon_0 A}$. $\frac{1}{2}=\frac{3}{8K_1}+\frac{1}{2K_2}+\frac{1}{8}$. With $K_1=1.25K_2$: solving gives $K_1\approx2.66$.

Question 996

Erythropoietin, a hormone, is primarily produced by _________ and is involved for RBC production:

Liver
Kidney✔️
Leukocytes
None of these

Correct Answer Logic:

Erythropoietin (EPO) is a glycoprotein hormone primarily produced by peritubular interstitial cells in the cortex of the kidney (about 90%) in response to hypoxia (low oxygen levels). A small amount is produced in the liver. EPO stimulates the bone marrow to increase the production of red blood cells (erythropoiesis), thereby increasing oxygen-carrying capacity.

Question 997

A batsman's average after 12 innings is 36. In the 13th inning he scores 87. What is his new average?

39
39.5
40✔️
40.5

Correct Answer Logic:

Total runs after 12 innings $= 12 \times 36 = 432$. After 13th inning $= 432 + 87 = 519$. New average $= \dfrac{519}{13} = 39.92 \approx 40$.

Civil Engineering QUESTION #2118

Question 1000

A thin-walled closed cylindrical pressure vessel of internal radius $r$, wall thickness $t$, and internal pressure $p$ has hoop (circumferential) stress $\sigma_h$ and longitudinal stress $\sigma_L$. Which relationship is correct?

$\sigma_h = \sigma_L = \dfrac{pr}{t}$
$\sigma_h = \dfrac{pr}{t}$ and $\sigma_L = \dfrac{pr}{2t}$✔️
$\sigma_h = \dfrac{pr}{2t}$ and $\sigma_L = \dfrac{pr}{t}$
$\sigma_h = \sigma_L = \dfrac{pr}{2t}$

Correct Answer Logic:

Hoop stress (resists diametral bursting): $\sigma_h = \dfrac{pr}{t}$. Longitudinal stress (resists end cap force): $\sigma_L = \dfrac{pr}{2t}$. Therefore hoop stress is exactly twice the longitudinal stress. This is why cylindrical pressure vessels fail by splitting longitudinally (hoop stress governs design), and why pipes are wound with more fibers circumferentially in filament-wound construction.
