Question 2

A synchronous generator with inertia constant $H = 5\,\text{MJ/MVA}$ is rated at $100\,\text{MVA}$. The angular momentum coefficient $M = GH/(\pi f_s)$ used in the swing equation (at $50\,\text{Hz}$) is approximately:

$3.18\,\text{MJ s/rad}$✔️
$5.00\,\text{MJ s/rad}$
$0.318\,\text{MJ s/rad}$
$1.59\,\text{MJ s/rad}$

Correct Answer Logic:

Stored kinetic energy $= H\times S_{rated} = 5\times100 = 500\,\text{MJ}$. Swing equation inertia: $M = \frac{GH}{\pi f_s} = \frac{100\times5}{\pi\times50} = \frac{500}{157.08} \approx 3.18\,\text{MJ·s/rad}$.

Question 13

The Maclaurin series for $f(Z)=Z^2e^{3Z}$ starts with:

$Z^2+3Z^3+\dfrac{9}{2}Z^4+\cdots$✔️
$Z^2+3Z^3+3Z^4+\cdots$
$Z^2+Z^3+\dfrac{1}{2}Z^4+\cdots$
$1+Z^2+3Z^3+\cdots$

Correct Answer Logic:

Use $e^{3Z}=\sum_{n=0}^\infty\dfrac{(3Z)^n}{n!}=1+3Z+\dfrac{9Z^2}{2}+\dfrac{9Z^3}{2}+\cdots$. Multiply by $Z^2$: $Z^2e^{3Z}=Z^2+3Z^3+\dfrac{9Z^4}{2}+\cdots$.

Physics QUESTION #7099

Question 16

A pendulum clock loses $12\text{ s}$ per day at $40^{\circ}\text{C}$ and gains $4\text{ s}$ per day at $20^{\circ}\text{C}$. Determine the correct time temperature and the linear expansion coefficient ($\alpha$) [cite: 446].

$60^{\circ}\text{C}$, $\alpha=1.85 \times 10^{-4}/^{\circ}\text{C}$
$30^{\circ}\text{C}$, $\alpha=1.85 \times 10^{-3}/^{\circ}\text{C}$
$55^{\circ}\text{C}$, $\alpha=1.85 \times 10^{-2}/^{\circ}\text{C}$
$25^{\circ}\text{C}$, $\alpha=1.85 \times 10^{-5}/^{\circ}\text{C}$✔️

Correct Answer Logic:

The error in time per day is $\Delta t = \frac{1}{2} \alpha \Delta \theta \times 86400$ [cite: 446].

Case 1: $12 = \frac{1}{2} \alpha (40 - \theta) \times 86400$
Case 2: $-4 = \frac{1}{2} \alpha (20 - \theta) \times 86400$
Dividing gives $\frac{12}{-4} = \frac{40-\theta}{20-\theta} \implies \theta = 25^{\circ}\text{C}$
Substituting back gives $\alpha = 1.85 \times 10^{-5}/^{\circ}\text{C}$[cite: 446].
