Question 3702

Which structure in fish helps them to maintain buoyancy?

Swim bladder✔️
Scales
Fins
None of these

Correct Answer Logic:

The swim bladder (gas bladder) is a gas-filled internal organ in most bony fish (Osteichthyes) that acts as a hydrostatic organ to control buoyancy. By adjusting the amount of gas in the swim bladder, fish can hover at different depths without expending energy swimming. Scales provide protection, and fins are used for locomotion and steering.

Is $\sqrt{9 + 16}$ equal to $\sqrt{9} + \sqrt{16}$?

Yes
No✔️
Sometimes
Cannot determine

Correct Answer Logic:

$\sqrt{9 + 16} = \sqrt{25} = 5$, but $\sqrt{9} + \sqrt{16} = 3 + 4 = 7$. Therefore $\sqrt{a+b} \neq \sqrt{a} + \sqrt{b}$

Physics QUESTION #993

Question 3711

A body of mass 100 g moves in a circular path of radius 2 m on a vertical plane. The velocity at point $A$ (bottom) is $10\ \text{m/s}$. The ratio of kinetic energies at point $B$ (at $30°$ from bottom) and $C$ (at top, $90°$ from $A$) is: (Take $g = 10\ \text{m/s}^2$):

$\dfrac{2+\sqrt{2}}{3}$
$\dfrac{2+\sqrt{3}}{3}$✔️
$\dfrac{3+\sqrt{3}}{2}$
$\dfrac{3-\sqrt{2}}{2}$

Correct Answer Logic:

Using energy conservation: $KE_B = KE_A - mgh_B$ and $KE_C = KE_A - mgh_C$. Height of B: $h_B = r - r\cos30° = 2(1-\frac{\sqrt{3}}{2})$. Height of C: $h_C = r = 2$ m. Ratio $\frac{KE_B}{KE_C} = \frac{5-mg(2-\sqrt{3})}{5-mg\cdot2} = \frac{2+\sqrt{3}}{3}$.

CISA QUESTION #1724

Question 3712

In the context of governance frameworks, what is the correct distinction between a standard and a guideline?

Standards are discretionary controls used alongside guidelines to support decision-making.
Standards are mandatory controls that give effect to a policy, whereas adherence to guidelines is discretionary.✔️
Guidelines are essential recommended controls supporting standards, both of which are discretionary.
Guidelines serve to designate policy intent, while standards substitute for policy when none exists.

Correct Answer Logic:

A standard establishes a minimum mandatory level of uniform compliance — organisations must meet it. A guideline, by contrast, provides advisory or recommended information to assist in decision-making when no applicable standard exists. Compliance with standards is obligatory; compliance with guidelines is at the discretion of the individual or organisation. The auditor assesses compliance with standards, not guidelines.

Physics QUESTION #1032

Question 3713

In some units, time $t$ and position $x$ of a particle satisfy $t = x^2 + x$. The acceleration of the particle is:

$+\dfrac{2}{(x+1)^3}$
$+\dfrac{2}{2x+1}$
$-\dfrac{2}{(x+2)^3}$
$-\dfrac{2}{(2x+1)^3}$✔️

Correct Answer Logic:

$\frac{dt}{dx} = 2x+1\Rightarrow v = \frac{dx}{dt} = \frac{1}{2x+1}$. Acceleration: $a = \frac{dv}{dt} = \frac{dv}{dx}\cdot v = \frac{-2}{(2x+1)^2}\cdot\frac{1}{2x+1} = \frac{-2}{(2x+1)^3}$.

Chemistry QUESTION #5581

Question 3720

In the reaction sequence $CH_3COOH \xrightarrow{LiAlH_4} A \xrightarrow{PCl_5} B \xrightarrow{Alc.\ KOH} C$, the product C is:

Ethylene ($CH_2=CH_2$)✔️
Acetyl chloride ($CH_3COCl$)
Acetaldehyde ($CH_3CHO$)
Acetylene ($HC\equiv CH$)

Correct Answer Logic:

Step 1: $CH_3COOH \xrightarrow{LiAlH_4} CH_3CH_2OH$ (ethanol, A). Step 2: $CH_3CH_2OH \xrightarrow{PCl_5} CH_3CH_2Cl$ (chloroethane, B). Step 3: $CH_3CH_2Cl \xrightarrow{Alc.\ KOH} CH_2=CH_2$ (ethylene/ethene, C) by elimination. The final product C is ethylene.
