Free Physics in Daily Life MCQs with Answers

• A. Water
• B. Steel
• C. Vacuum
• D. Air

Explanation: Sound is a mechanical wave and requires a material medium whose particles can vibrate.

• A. Solid
• B. Liquid
• C. Gas
• D. NOT

Explanation: Gas particles move most freely and rapidly, so they have the highest average kinetic energy among the three common states.

• A. Electromagnetic
• B. Neutral
• C. Chemical
• D. Acoustic

Explanation: Light is an electromagnetic signal because it consists of oscillating electric and magnetic fields and does not need a material medium to…

• A. Isaac Newton
• B. Galileo Galilei
• C. Albert Einstein
• D. Nikola Tesla

Explanation: Isaac Newton formulated the three laws of motion and the law of universal gravitation.

• A. Space waves
• B. Cable waves
• C. Antenna waves
• D. None of thesePhysics Mcqs

Explanation: Line-of-sight radio communication uses space waves, which travel directly through the lower atmosphere from transmitting to receiving…

• A. Reflection
• B. Refraction
• C. Diffraction
• D. None of these

Explanation: Optical fibre guides light by total internal reflection at the boundary between its denser core and less-dense cladding.

• A. Alpha particle
• B. Neutron
• C. Electron
• D. Proton
• E. All of theseExam preparation materials

Explanation: A neutron has no net electric charge, whereas an alpha particle and proton are positive and an electron is negative.

• A. Water waves
• B. Color contrast
• C. Time
• D. Sound waves

Explanation: A chronometer is a precision instrument for measuring or keeping time, so its measured quantity is time.

• A. Surface Action
• B. Capillary Action
• C. Viscosity
• D. Boldness

Explanation: Tiny pores in blotting paper act like narrow tubes, drawing liquid through them by capillary action.

• A. Ampere
• B. Coulomb
• C. Ohm
• D. Volt

Explanation: The coulomb is the SI unit of electric charge, equal to the charge transferred by a current of one ampere in one second.

• A. Water expands on freezing
• B. Bottle contracts at freezing point
• C. temperature outside the bottle is less than that inside the bottle.
• D. None of the above

Explanation: Water expands when it freezes because its molecules form an open crystal structure, increasing its volume.

• A. Prop him up if he falls
• B. Spread out his weight and reduce the pressure on the rope
• C. Add extra weight to keep the rope tightly stretched
• D. To keep the Center of gravity always above vertically above the rope

Explanation: The long pole helps the walker control balance by keeping the combined centre of gravity vertically above the rope.

• A. Protons
• B. Electrons
• C. Neutrons
• D. None

Explanation: Beta-minus particles are fast-moving electrons emitted when a neutron changes into a proton.

• A. Electron and Proton
• B. Two Protons and two Neutrons
• C. Three protons and three Neutrons
• D. None

Explanation: An alpha particle is the nucleus of a helium-4 atom, containing two protons and two neutrons.

• A. Pythagorus
• B. Archimedes
• C. Aristotle
• D. None

Explanation: Pythagoras is traditionally associated with the Pythagorean theorem, a foundational result in geometry relating the sides of a right…

• A. Velocity
• B. Temperature
• C. Mass
• D. None OF These

Explanation: The coulomb is the SI unit of electric charge, equal to the charge transferred by one ampere in one second.

• A. A binocular
• B. A camera
• C. An epidiascope
• D. A stereoscope

Explanation: A stereoscope presents slightly different views to the two eyes, allowing the brain to combine them into a three-dimensional image.

• A. Surface tension
• B. Viscosity
• C. Specific gravity
• D. Elasticity

Explanation: Surface tension makes water form droplets and resist spreading across the fibres of a treated coat or tent.

• A. Viscosity of ink
• B. Capillary action phenomenon
• C. Diffusion of ink through the blotting
• D. Siphon action

Explanation: Blotting paper contains very fine pores, and adhesion plus capillary action draws the ink into these narrow spaces.

• A. Increasing the temperature of water
• B. Reacting chemically with dirt
• C. Reducing the surface tension of water
• D. Dissolving dirt

Explanation: Detergents lower water's surface tension, allowing it to spread through cloth and reach dirt more easily.
