PPSC One-Paper MCQ Test Everyday Science flashcards — 50 questions with answers

State Newton's first law of motion.
A body remains at rest or in uniform motion in a straight line unless acted upon by an external force (law of inertia).
What is the SI unit of force, and how is it defined?
The newton (N). One newton is the force that gives a 1 kg mass an acceleration of 1 m/s squared.
Write the formula for kinetic energy.
KE = 1/2 m v squared, where m is mass and v is velocity.
What is the acceleration due to gravity on Earth's surface (standard value)?
Approximately 9.8 m/s squared (often taken as 9.81 m/s squared).
State the law of conservation of energy.
Energy can neither be created nor destroyed; it can only be transformed from one form to another. Total energy stays constant.
What is the speed of light in a vacuum?
Approximately 3 x 10^8 metres per second (about 300,000 km/s).
What is the speed of sound in air at room temperature?
Approximately 343 m/s (about 330-340 m/s), much slower than light.
Why does a stick appear bent when partly placed in water?
Because of refraction the bending of light as it passes from water (denser) to air (rarer).
Which type of lens is used to correct short-sightedness (myopia)?
A concave (diverging) lens.
Which type of mirror is used in vehicle rear-view/side mirrors and why?
A convex mirror, because it gives an erect, diminished image and a wider field of view.
State Ohm's law and its formula.
The current through a conductor is proportional to the voltage across it: V = I R (Voltage = Current x Resistance).
What is the SI unit of electric current?
The ampere (A).
What is the SI unit of electrical resistance?
The ohm.
What is electric power and its basic formula?
Power is the rate of using electrical energy: P = V I (also P = I squared R), measured in watts.
What are the magnetic poles of the Earth, and how does a compass align?
Earth acts like a giant magnet; a compass needle aligns roughly north-south, its north pole pointing toward Earth's magnetic north.
What is the SI base unit of length, mass, and time?
Metre (length), kilogram (mass), and second (time).
How many SI base units are there, and name any two besides metre, kilogram, second?
Seven base units; examples include ampere (current), kelvin (temperature), mole (amount), and candela (luminous intensity).
What is the unit of temperature in the SI system and the value of absolute zero in Celsius?
The kelvin (K); absolute zero is -273.15 degrees Celsius (0 K).
What are the three subatomic particles and their charges?
Proton (positive), neutron (neutral), and electron (negative).
What is the atomic number of an element?
The number of protons in the nucleus of its atom.

What is an isotope?
Atoms of the same element with the same number of protons but different numbers of neutrons (different mass numbers).
Who arranged the modern periodic table and on what basis?
Henry Moseley arranged it by increasing atomic number; Mendeleev's earlier table was by atomic mass.
What does the pH scale measure, and what value is neutral?
It measures acidity/alkalinity from 0 to 14; 7 is neutral, below 7 is acidic, above 7 is basic.
What is produced when an acid reacts with a base?
A salt and water (neutralization reaction).
Give the chemical name and formula of common table salt.
Sodium chloride, NaCl.
What is the chemical formula of water and of carbon dioxide?
Water is H2O; carbon dioxide is CO2.
Which gas is most abundant in Earth's atmosphere and what percentage?
Nitrogen, about 78 percent.
What gas do humans exhale and plants absorb for photosynthesis?
Carbon dioxide (CO2).
What is the common name for sodium bicarbonate, used in cooking?
Baking soda.
What gas is used to fill weather balloons and airships because it is light and non-flammable?
Helium.
How many bones are there in the adult human body?
206 bones.
Which organ pumps blood throughout the human body?
The heart.
What is the functional unit of the kidney called?
The nephron.
What is the basic structural and functional unit of life?
The cell.
What molecule carries genetic information, and what is its full name?
DNA Deoxyribonucleic Acid.
Who is known as the father of genetics, and what did he study?
Gregor Mendel, who studied inheritance using pea plants.
Which vitamin deficiency causes scurvy, and what food prevents it?
Vitamin C deficiency; citrus fruits prevent it.
Which vitamin deficiency causes night blindness?
Vitamin A deficiency.
Which vitamin is produced in the skin through sunlight and prevents rickets?
Vitamin D.
Which deficiency causes goitre, and which element is involved?
Iodine deficiency causes goitre (enlarged thyroid gland).
What is photosynthesis?
The process by which green plants use sunlight, carbon dioxide, and water to make glucose and release oxygen.
What green pigment in plants captures light energy for photosynthesis?
Chlorophyll.
How many planets are in the solar system, and which is the largest?
Eight planets; Jupiter is the largest.
Which planet is closest to the Sun and which is known as the Red Planet?
Mercury is closest to the Sun; Mars is the Red Planet.
What layer of the atmosphere contains the ozone layer that absorbs UV radiation?
The stratosphere.
What instrument measures the magnitude of earthquakes, and on what scale?
A seismograph records earthquakes; magnitude is often given on the Richter scale.
Who proposed the theory of universal gravitation and the laws of motion?
Sir Isaac Newton.
Which branch of science studies living organisms, and which studies matter and energy?
Biology studies living organisms; physics studies matter and energy.
What instrument is used to measure atmospheric pressure?
The barometer.
What instrument is used to measure relative humidity in the air?
The hygrometer.
