Question 2

The free response of an underdamped system ($\zeta < 1$) is:

$x(t) = e^{-\alpha t}(C_1\sin\omega_d t + C_2\cos\omega_d t)$ where $\alpha=\zeta\omega_n$✔️
$x(t) = A\sin(\omega_n t + \phi)$ (pure harmonic)
$x(t) = C_1 e^{-\lambda_1 t} + C_2 e^{-\lambda_2 t}$
$x(t) = (C_1t + C_2)e^{-\alpha t}$

Correct Answer Logic:

For the underdamped case, the solution is the exponentially decaying sinusoid: $x=e^{-\alpha t}(C_1\sin\omega_d t+C_2\cos\omega_d t)$. Option 3 is for overdamped; option 4 is for critically damped.

Question 3

Under section 49(2), for purposes of calculating default surcharge, the period of default is reckoned from which specific day?

The first day of the relevant tax period

Question 4

For a particle moving in polar coordinates $(r,\theta)$, the transverse component of acceleration $a_\theta$ is:

$a_\theta = \ddot{r} - r\dot{\theta}^2$
$a_\theta = r\ddot{\theta} + 2\dot{r}\dot{\theta}$✔️
$a_\theta = r\ddot{\theta} - 2\dot{r}\dot{\theta}$
$a_\theta = \ddot{\theta}/r$

Correct Answer Logic:

In polar coordinates, acceleration components are: radial $a_r=\ddot{r}-r\dot{\theta}^2$ and transverse $a_\theta=r\ddot{\theta}+2\dot{r}\dot{\theta}$. The term $2\dot{r}\dot{\theta}$ is the Coriolis acceleration component in polar form.

Question 6

For internal forced convection in a fully developed turbulent pipe flow (Dittus-Boelter equation), the Nusselt number is:

$Nu_D = 0.332 Re_D^{0.8} Pr^{0.4}$
$Nu_D = 0.023 Re_D^{0.8} Pr^n$ where $n=0.4$ for heating and $n=0.3$ for cooling✔️
$Nu_D = 3.66$ (constant, for laminar flow)
$Nu_D = 0.664 Re_D^{1/2} Pr^{1/3}$

Correct Answer Logic:

The Dittus-Boelter equation for turbulent pipe flow: $Nu_D=0.023Re_D^{0.8}Pr^n$ with $n=0.4$ for heating and $n=0.3$ for cooling.

Question 8

Which of the following is the dominant generation in the life cycle of Pteridophytes?

Sporophyte✔️
Gametophyte
Seedling
Embryo

Correct Answer Logic:

In pteridophytes (ferns and allies), the sporophyte generation (diploid, 2n) is the dominant, independent, and conspicuous phase — the familiar leafy fern plant. The gametophyte (haploid, n) is a small, inconspicuous, short-lived prothallus. This contrasts with bryophytes where the gametophyte is dominant, and represents an evolutionary advancement.

Question 14

Using the Cauchy Residue Theorem, $\oint_{|Z|=2}\dfrac{5Z-2}{Z(Z-1)}\,dZ$ equals:

$2\pi i$
$4\pi i$
$6\pi i$
$10\pi i$✔️

Correct Answer Logic:

Partial fractions: $\dfrac{5Z-2}{Z(Z-1)}=\dfrac{2}{Z}+\dfrac{3}{Z-1}$. Both poles $Z=0$ and $Z=1$ lie inside $|Z|=2$. By residue theorem: $2\pi i(\text{Res at }0+\text{Res at }1)=2\pi i(2+3)=10\pi i$.
