A projectile from Earth (speed $5\text{ m/s}$ at angle $\theta$) follows the same trajectory as one from another planet (speed $3\text{ m/s}$, same angle). The gravitational acceleration on that planet is ($g_{\text{Earth}} = 9.8\text{ m/s}^2$):

$3.5\text{ m/s}^2$✔️
$5.9\text{ m/s}^2$
$16.3\text{ m/s}^2$
$110.8\text{ m/s}^2$

Correct Answer Logic:

For identical trajectories at the same angle, the ratio $\dfrac{u^2}{g}$ must be equal (since all trajectory dimensions scale with $u^2/g$):

$\dfrac{25}{9.8} = \dfrac{9}{g'} \Rightarrow g' = \dfrac{9 \times 9.8}{25} = \dfrac{88.2}{25} \approx \mathbf{3.5\text{ m/s}^2}$

Dairy Food Science and Technology QUESTION #5902

Question 11167

The phenomenon of lactose crystallization in concentrated milk products causing a gritty texture is called:

Syneresis
Maillard browning
Sandiness due to $\alpha$-lactose monohydrate crystal formation (crystals $>30\;\mu\text{m}$)✔️
Creaming

Correct Answer Logic:

When lactose supersaturation occurs in condensed or sweetened condensed milk or ice cream, large $\alpha$-lactose monohydrate crystals ($>30\;\mu\text{m}$) form causing sandiness or grittiness. Control involves rapid cooling, seeding with fine lactose crystals, or use of lactase.

Question 11168

A homeowner sells their house but does not record the deed. A week later, the same homeowner sells the house again to a different buyer who knows nothing about the first sale and records their deed immediately. In a 'Notice' jurisdiction, who owns the house?

The first buyer.
The second buyer.✔️
They share it.
The original owner.

Correct Answer Logic:

In a 'Notice' jurisdiction, a subsequent bona fide purchaser (BFP) who takes without notice of the prior unrecorded interest wins, regardless of whether they record first (though recording is still wise).

Physics QUESTION #7075

Question 11169

An X-ray tube functions at a potential of $1.24$ million volts. Calculate the shortest wavelength produced by the photons in this tube.

$10^{-3} \text{ nm}$✔️
$10^{-2} \text{ nm}$
$10^{-4} \text{ nm}$
$10^{-1} \text{ nm}$

Correct Answer Logic:

The shortest wavelength ($\lambda_{min}$) is given by $\lambda = \frac{hc}{eV}$. Using $hc \approx 1240 \text{ eV}\cdot\text{nm}$, we have $\lambda = \frac{1240 \text{ eV}\cdot\text{nm}}{1.24 \times 10^6 \text{ eV}} = 1000 \times 10^{-6} \text{ nm} = 10^{-3} \text{ nm}$.

Bio-Technology QUESTION #10562

Question 11172

In eukaryotic cells, fatty acid synthesis occurs in the cytoplasm, whereas fatty acid degradation (β-oxidation) occurs in:

The nucleus
The endoplasmic reticulum
The peroxisome✔️
The Golgi apparatus

Correct Answer Logic:

In eukaryotes, β-oxidation of fatty acids occurs in the peroxisome (and to a lesser extent, mitochondria). Separating synthesis (cytoplasm) from degradation (peroxisome) prevents futile cycling. Peroxisomes contain catalase and peroxidase that handle the H₂O₂ generated during oxidation. This compartmentalisation is a key metabolic control strategy in eukaryotes.

Question 11173

Under the Pakistan Tourist Destinations course, which of the following is correctly classified as a 'cultural heritage resource' rather than a natural resource?

The Karakoram mountain range
Mangrove ecosystems
Buddhist stupas, Sikh shrines, and Muslim tombs✔️
The Indus River and its tributaries

Correct Answer Logic:

The Pakistan Tourist Destinations course classifies Buddhist, Sikh, Hindu, and Muslim sites (stupas, shrines, tombs, mosques) as cultural heritage resources — specifically listed under 'Muslim, Buddhist, Sikh, Hindu, Socio-cultural resources.' Natural landforms and water bodies are classified separately as natural resources.

Physics QUESTION #7088

Question 11176

A wire has length $l_1$ at tension $T_1$ and $l_2$ at tension $T_2$. Find its original length.

$\frac{T_1 l_1 - T_2 l_2}{T_2 - T_1}$
$\frac{l_1 + l_2}{2}$
$\frac{T_2 l_1 + T_1 l_2}{T_2 + T_1}$
$\frac{T_2 l_1 - T_1 l_2}{T_2 - T_1}$✔️

Correct Answer Logic:

Using Hooke's Law: $l = L + \frac{TL}{AY} \implies l = L + kT$ where $k = \frac{L}{AY}$.

$l_1 = L + kT_1$ and $l_2 = L + kT_2$
Subtracting: $l_2 - l_1 = k(T_2 - T_1) \implies k = \frac{l_2 - l_1}{T_2 - T_1}$
Substitute $k$ back: $L = l_1 - T_1(\frac{l_2 - l_1}{T_2 - T_1}) = \frac{T_2 l_1 - T_1 l_2}{T_2 - T_1}$.
