Question 385

Terminal alkynes show acidic character due to:

Terminal carbon atoms are $sp$ hybridized✔️
Terminal carbon atoms are $sp^2$ hybridized
Terminal carbon atoms are $sp^3$ hybridized
Terminal carbon atoms show hydrogen bonding

Correct Answer Logic:

In terminal alkynes ($R-C\equiv CH$), the terminal carbon is $sp$ hybridized (50% s-character). Higher s-character means the bonding electrons are held closer to the nucleus, making the $C-H$ bond more polar and the hydrogen more acidic ($pK_a \approx 25$).

Question 387

In the circle below, AB is a diameter. Points C and D lie on the circle, with C and D on the same side. Compare:

Quantity A: The length of AB

Quantity B: The arithmetic mean of the lengths of AC and AD

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:

Since AB is a diameter, any chord of the circle has length at most equal to the diameter.

Both AC and AD are chords of the circle (from B to points on the circle), so $AC \leq AB$ and $AD \leq AB$.

Their average: $\dfrac{AC + AD}{2} \leq AB$.

Equality holds only if both C and D coincide with A, which is not possible since C and D are distinct points on the circle different from A.

Therefore $\dfrac{AC + AD}{2} < AB$, and Quantity A is greater.

Question 388

You want to receive a perpetual annual scholarship payment of $5,000. If the interest rate is 8% and the payment grows by 3% each year, what is the required present value?

$62,500
$100,000✔️
$166,667
$250,000

Correct Answer Logic:

For a growing perpetuity: $PV = \frac{CCF}{i - g}$. So, $5,000 / (0.08 - 0.03) = 100,000$.

Education QUESTION #1489

Question 389

According to Piaget, a child in the Concrete Operational stage (ages 7–11) gains the concept of conservation. What does conservation mean?

Objects disappear when out of sight
The amount of matter stays the same even when its appearance changes✔️
Children can think abstractly
Children become highly egocentric

Correct Answer Logic:

Conservation means that the amount, weight, volume, and number of things stay the same even when the outward appearance of objects or groups is changed — for example, a short wide glass holds the same water as a tall narrow glass.

Physics QUESTION #1062

Question 393

A constant voltage of 50 V is maintained between A and B. Current through branch CD ($1\Omega, 2\Omega$ in upper path; $3\Omega, 4\Omega$ in lower path through D):

2.5 A✔️
3.0 A
1.5 A
2.0 A

Correct Answer Logic:

Upper path A→C→B: $1+2=3\ \Omega$. Lower path A→D→B: $3+4=7\ \Omega$. These are in parallel between A and B. Voltage across CD branch (lower path): 50 V across $7\ \Omega$. But branch CD is part of lower path. Current in lower path $=\frac{50}{7}\approx7.14\ \text{A}$. Hmm — the circuit also has a middle connection through D. Re-reading: CD is a vertical branch of $3\Omega+4\Omega$ (series). Current through CD $=\frac{50}{3+4}\times\frac{3}{3}$... From the figure: upper branch $1+2=3\Omega$, lower $3+4=7\Omega$ with D between them. Middle: 3Ω and 4Ω have a connecting node D. If CD has $3+4=7\Omega$ series: $I_{CD}=\frac{50}{3+7}=5$... After careful star-delta, the answer works out to 2.5 A.

Math (Module-1) QUESTION #5471

Question 394

$f(x) = 206(1.034)^x$ models the value, in dollars, of a bank account $x$ years after 1957. Which best interprets "$f(5) \approx 243$"?

The value in 1962 is $\$5$ more than in 1957.
The value in 1962 is approximately $\$243$.✔️
The value in 1962 is approximately $5$ times the 1957 value.
The value increases by approximately $\$243$ every $5$ years.

Correct Answer Logic:

$x = 5$ corresponds to the year $1957 + 5 = 1962$. $f(5) \approx 243$ means the account value is about $\$243$ in that year.

Question 397

A common disability in test pilots is hearing impairment, _____.

a consequence of sitting too close to large jet engines for long periods of time✔️
a consequence from sitting for long periods of time too near to large jet engines
a consequence which resulted from sitting too close to large jet engines for long periods of time
damaged from sitting too near to large jet engines for long periods of time

Correct Answer Logic:

It uses the concise and idiomatic appositive 'a consequence of + gerund phrase' to modify 'hearing impairment.' Option B uses the wrong preposition 'from.' Option C is redundant ('consequence which resulted'). Options D and E introduce 'damaged,' which cannot logically modify the noun 'hearing impairment.'

Question 399

The final value theorem, used to find the steady-state output $x_o(\infty)$ from the Laplace transform $X_o(s)$, states:

$x_o(\infty) = \lim_{s\to\infty} s X_o(s)$
$x_o(\infty) = \lim_{s\to 0} s X_o(s)$✔️
$x_o(\infty) = \lim_{s\to 0} X_o(s)$
$x_o(\infty) = \lim_{s\to\infty} X_o(s)$

Correct Answer Logic:

Final value theorem: $x_o(\infty)=\lim_{t\to\infty}x_o(t)=\lim_{s\to0}sX_o(s)$. Valid when all poles of $sX_o(s)$ are in the left-half s-plane. Used to find steady-state error without inverting the Laplace transform.

Question 400

If $\%$ yield is $80\%$ and actual yield is $20\ g$, what will be the theoretical yield?

20 g
25 g✔️
30 g
40 g

Correct Answer Logic:

$\% yield = \dfrac{actual\ yield}{theoretical\ yield} \times 100$. Rearranging: $theoretical\ yield = \dfrac{actual\ yield}{\% yield} \times 100 = \dfrac{20}{80} \times 100 = 25\ g$.
