Which of the following situations are possible?

i. A body having velocity east and acceleration west.
ii. A body having constant velocity and variable acceleration.
iii. A body having zero velocity and non-zero acceleration.

Explanation

Situation (i) is possible (e.g. decelerating vehicle moving East). Situation (iii) is possible (e.g. a ball at the top of its flight has zero velocity but non-zero gravitational acceleration). Situation (ii) is impossible because constant velocity implies acceleration must be strictly zero.

صورتحال (i) ممکن ہے (بریک لگانے پر گاڑی مشرق جا رہی ہو اور اسراع مغرب ہو)۔ صورتحال (iii) بھی ممکن ہے (مثلاً ہوا میں اوپر پھینکی گئی گیند جو اپنی زیادہ سے زیادہ بلندی پر رکتی ہے لیکن کشش ثقل کا اسراع جاری رہتا ہے)۔ صورتحال (ii) ناممکن ہے۔

15📚🔬 Forensic SciencePrinting Technology

Lithography printing has the following characteristics:
a. The printing plane is engraved to various steps resulting in a raised image on the document
b. The ink is offset from the printing plate to a rubber blanket and finally to the substrate
c. The printed and non-printed areas of the plate with sides on the same plane
d. It relies on the principle that oil and water do not mix
e. The printing process utilises raised type of embossed printed images

Explanation

Lithography is planographic (c: print/non-print areas are on the same plane) and works on the oil-and-water repulsion principle (d). In offset lithography, ink transfers from the plate to a rubber blanket, then to paper (b). Engraving/raised prints (a, e) are intaglio or letterpress features. Thus, b, c, and d only are correct.

لیتھوگرافی (Lithography) کی خصوصیات یہ ہیں: روشنائی پلیٹ سے ربڑ کمبل پر اور پھر کاغذ پر منتقل ہوتی ہے (b)، پرنٹ ہونے والا حصہ اسی سطح پر ہوتا ہے (planographic - c)، اور یہ تیل اور پانی کے نہ ملنے کے اصول پر کام کرتی ہے (d)۔ ابھار والی پرنٹنگ (a, e) اس میں نہیں ہوتی۔ یعنی b, c اور d درست ہیں۔

Explanation

Uplift pressure on a gravity dam is controlled by: 1. Upstream cut-off walls (reduces seepage head). 2. Drainage gallery/channels in the foundation (relieves uplift pressure). 3. Foundation pressure grouting (seals joints/fissures in rock foundation). Thus, all three methods are effective.

ڈیم پر پانی کے نیچے سے لگنے والے بوجھ (uplift pressure) کو کنٹرول کرنے کے لیے: اپ اسٹریم پر کٹ آف بنانا، ڈیم اور فاؤنڈیشن کے درمیان ڈرینیج گیلری بنانا اور بنیاد میں پریشر گراؤٹنگ کرنا، یہ تینوں طریقے استعمال کیے جاتے ہیں۔

On a foggy day, two bus drivers spot each other. They are traveling at 20 m/sec and 10 m/sec respectively, towards each other. Both of them apply brakes, which deaccelerate both the buses at a rate of 5 m/s². How far apart will they be, when they have come to stop.

Explanation

Stopping distance

s = \frac{u^2}{2a}

. For Bus 1:

s_1 = \frac{20^2}{2 \times 5} = 40 \text{ m}

. For Bus 2:

s_2 = \frac{10^2}{2 \times 5} = 10 \text{ m}

. Total stopping distance =

s_1 + s_2 = 40 + 10 = 50 \text{ m}

. Thus, they need to be 50 meters apart to avoid a collision.

بس 1 کا فاصلہ: 20² / 10 = 40 میٹر۔ بس 2 کا فاصلہ: 10² / 10 = 10 میٹر۔ دونوں بسوں کے رکنے کا کل فاصلہ = 40 + 10 = 50 میٹر ہے۔

147📚📖 General EnglishComprehension Passage: Renewable Energy

Read the following passage carefully to answer the question:

"In an era marked by environmental concerns and the urgent need for action against climate change, sustainable energy has emerged as a beacon of hope. Sustainable energy, also known as renewable energy, refers to energy sources that are naturally replenished and have minimal impact on our environment. The various energy sources are solar, wind, hydroelectric, geothermal, and biomass. The adoption of sustainable energy holds immense promise in addressing some of the most pressing challenges facing humanity today. One of its primary goals is to reduce dependence on finite fossil fuels, such as coal, oil, and natural gas, which contribute significantly to greenhouse gas emissions and air pollution. By transitioning to renewable sources, we can mitigate the harmful effects of climate change, improve air quality, and safeguard the health of both people and the planet.

Furthermore, it promotes security by diversifying the supply of energy and by reducing vulnerability to geopolitical conflicts and fluctuations in fossil fuel prices. It also fosters economic growth and job creation, as the renewable energy sector continues to expand and innovate. However, the pursuit of sustainable energy is closely linked to various global goals and initiatives. The United Nations Sustainable Development Goals (SDGs), emphasize the importance of ensuring access to reliable, sustainable, and modern energy for all. Additionally, the Paris Agreement aims to limit the increase in the global average temperature to well below 2°C above pre-industrial level.

148📚📖 General EnglishComprehension Passage: Renewable Energy

Read the following passage carefully to answer the question:

"In an era marked by environmental concerns and the urgent need for action against climate change, sustainable energy has emerged as a beacon of hope. Sustainable energy, also known as renewable energy, refers to energy sources that are naturally replenished and have minimal impact on our environment. The various energy sources are solar, wind, hydroelectric, geothermal, and biomass. The adoption of sustainable energy holds immense promise in addressing some of the most pressing challenges facing humanity today. One of its primary goals is to reduce dependence on finite fossil fuels, such as coal, oil, and natural gas, which contribute significantly to greenhouse gas emissions and air pollution. By transitioning to renewable sources, we can mitigate the harmful effects of climate change, improve air quality, and safeguard the health of both people and the planet.

Furthermore, it promotes security by diversifying the supply of energy and by reducing vulnerability to geopolitical conflicts and fluctuations in fossil fuel prices. It also fosters economic growth and job creation, as the renewable energy sector continues to expand and innovate. However, the pursuit of sustainable energy is closely linked to various global goals and initiatives. The United Nations Sustainable Development Goals (SDGs), emphasize the importance of ensuring access to reliable, sustainable, and modern energy for all.

Manisha takes twice as much time as Usha to complete a work and Ravi does it in the same time as Manisha and Usha together. If all three working together can finish the work in 7 days, then the time taken by Manisha to finish the work is:

Explanation

Let Usha's time be

x

days

\implies

Manisha's time

= 2x

days.
Combined 1-day work of Manisha and Usha:

\frac{1}{2x} + \frac{1}{x} = \frac{3}{2x}

Ravi's 1-day work is equal to Manisha + Usha together

= \frac{3}{2x}

.
All three together in 1 day:

\frac{3}{2x} + \frac{3}{2x} = \frac{6}{2x} = \frac{3}{x} = \frac{1}{7} \implies x = 21\text{ days}

Time taken by Manisha

= 2x = 2 \times 21 = 42\text{ days}

.

उषा का समय

= x

, मनीषा का समय

= 2x

।
मनीषा + उषा का 1 दिन का काम

= \frac{1}{2x} + \frac{1}{x} = \frac{3}{2x}

(रवि का भी काम)।
तीनों का 1 दिन का कुल काम

= \frac{3}{2x} + \frac{3}{2x} = \frac{3}{x} = \frac{1}{7} \implies x = 21
