SPSC Test General Knowledge and Everyday Science flashcards — 50 questions with answers
What is the SI unit of force, and what is it equivalent to in base units?
The newton (N). 1 N = 1 kg·m/s².
State Newton's Second Law of Motion as a formula.
Force equals mass times acceleration: F = ma.
What is the speed of light in a vacuum (approximate value)?
Approximately 3 × 10⁸ metres per second (300,000 km/s).
Define 'work' in physics and give its SI unit.
Work is the product of force and displacement in the direction of the force (W = F × d). Its SI unit is the joule (J).
What is the chemical formula of common table salt, and what two ions form it?
Sodium chloride, NaCl, formed from sodium ions (Na⁺) and chloride ions (Cl⁻).
On the pH scale, what values represent acidic, neutral, and basic (alkaline) solutions?
pH below 7 is acidic, pH 7 is neutral, and pH above 7 is basic/alkaline.
What gas do plants absorb and what gas do they release during photosynthesis?
They absorb carbon dioxide (CO₂) and release oxygen (O₂).
What is the chemical name and formula of baking soda?
Sodium bicarbonate (sodium hydrogen carbonate), NaHCO₃.
Which organ in the human body produces insulin, and what does insulin regulate?
The pancreas produces insulin, which regulates blood glucose (sugar) levels.
Name the four chambers of the human heart.
Right atrium, right ventricle, left atrium, and left ventricle.
What is the functional unit of the kidney called?
The nephron.
Which part of the human brain controls balance and coordination of movement?
The cerebellum.
Which vitamin is produced by the skin in response to sunlight, and what does it help absorb?
Vitamin D, which helps the body absorb calcium (and phosphorus).
What deficiency causes the disease scurvy, and which vitamin prevents it?
Scurvy is caused by a deficiency of Vitamin C (ascorbic acid).
What are the three main macronutrients required by the human body?
Carbohydrates, proteins, and fats (lipids).
Which mineral deficiency commonly causes goitre, and what gland is affected?
Iodine deficiency causes goitre, affecting the thyroid gland.
What type of pathogen causes malaria, and which insect transmits it?
A protozoan parasite (Plasmodium) causes malaria, transmitted by the female Anopheles mosquito.
What is the difference between active and passive immunity?
Active immunity is produced by the body's own immune response (e.g., after infection or vaccination) and is long-lasting; passive immunity is acquired by receiving ready-made antibodies (e.g., from the mother or an injection) and is temporary.
Which type of white blood cells produce antibodies?
B-lymphocytes (B-cells).
What does a vaccine contain, and how does it protect the body?
A vaccine contains weakened, killed, or part of a pathogen (or its antigens) that stimulate the immune system to produce antibodies and memory cells, giving immunity without causing the disease.

In an ecosystem, what is the role of decomposers?
Decomposers (such as bacteria and fungi) break down dead organisms and waste, recycling nutrients back into the soil and environment.
Define a 'food chain' and name its first trophic level.
A food chain shows the flow of energy from one organism to another through feeding. Its first trophic level consists of producers (green plants/autotrophs).
What is biodiversity?
Biodiversity is the variety of all living organisms — including the diversity of species, genes, and ecosystems — in a given area or on Earth.
Which gas is the primary contributor to the greenhouse effect from human activity?
Carbon dioxide (CO₂).
Name the layer of the atmosphere that contains the ozone layer and protects Earth from UV radiation.
The stratosphere.
What is acid rain, and which two gases mainly cause it?
Acid rain is precipitation with high acidity caused by air pollutants; it is mainly produced by sulphur dioxide (SO₂) and nitrogen oxides (NOₓ).
Name two major natural resources/minerals found in Sindh, Pakistan.
Natural gas and coal (e.g., the Thar coalfield); Sindh also has limestone and oil.
Where is Pakistan's largest coal reserve located, and in which province?
The Thar coalfield, located in the Tharparkar district of Sindh.
What does 'CPU' stand for, and what is its function?
Central Processing Unit; it is the 'brain' of the computer that carries out instructions and performs calculations and logic operations.
What is the difference between RAM and ROM?
RAM (Random Access Memory) is volatile, temporary memory that loses data when power is off; ROM (Read-Only Memory) is non-volatile and retains data permanently, storing instructions like the boot/firmware.
What does 'HTTP' stand for in web addresses?
HyperText Transfer Protocol.
What does 'IP' stand for in 'IP address'?
Internet Protocol.
What is a geostationary satellite?
A satellite orbiting Earth at about 36,000 km above the equator with an orbital period equal to Earth's rotation (24 hours), so it appears stationary relative to a point on the ground; used for communication and weather monitoring.
What does 'GPS' stand for, and what is its main use?
Global Positioning System; it uses a network of satellites to determine precise location, navigation, and time anywhere on Earth.
What is the name of Pakistan's space agency?
SUPARCO (Space and Upper Atmosphere Research Commission).
What is DNA, and what does it carry?
DNA (deoxyribonucleic acid) is the molecule that carries the genetic information/hereditary instructions in living organisms.
What is genetic engineering?
Genetic engineering is the direct manipulation of an organism's genes/DNA using biotechnology to alter its characteristics or produce desired products.
How do you calculate a percentage of a number? Give the formula.
Percentage of a number = (percentage ÷ 100) × the number. For example, 20% of 50 = (20/100) × 50 = 10.
If a price increases from 200 to 250, what is the percentage increase?
Increase = 50; percentage increase = (50 ÷ 200) × 100 = 25%.
What is the formula for simple interest?
Simple Interest = (Principal × Rate × Time) ÷ 100, i.e., S.I. = PRT/100.
If the ratio of boys to girls is 3:2 in a class of 30 students, how many are boys?
Total parts = 5; each part = 30 ÷ 5 = 6; boys = 3 × 6 = 18.
What is the formula for the average (arithmetic mean) of a set of numbers?
Average = (sum of all values) ÷ (number of values).
Two numbers are in the ratio 4:5. If their sum is 81, find the larger number.
Total parts = 9; each part = 81 ÷ 9 = 9; larger number = 5 × 9 = 45.
In a logical sequence 2, 6, 12, 20, 30, what is the next number?
42. The differences increase by 2 each time (4, 6, 8, 10, 12), so 30 + 12 = 42.
In a pie chart, what total angle represents 100% of the data, and what angle represents 25%?
360° represents 100%; therefore 25% is represented by 90°.
Which is the largest continent by area, and which is the smallest?
Asia is the largest continent; Australia (Oceania) is the smallest.
What is the longest river in the world, and on which continent is it located?
The Nile River (about 6,650 km), located in Africa. (The Amazon is a close rival in length.)
Where is the headquarters of the United Nations located?
New York City, USA.
