Review the solved problems below to understand question phrasing, answer choices, and step-by-step solution logic prior to starting the full interactive practice drill:
Sample Question 1
Physics
Easy • General Knowledge
Ordinary dry air consists of the following:
A
Nitrogen
B
Oxygen
C
Argon
D
Carbon dioxide
โ Correct Answer: A - Nitrogen
๐ Step-by-Step Solution & Conceptual Rationale:
Nitrogen is the most abundant gas in Earth's atmosphere, making up approximately 78% of dry air by volume.
Sample Question 2
Physics
Medium • General Knowledge
The resolving power of an electron microscope is much higher than that of an ordinary light microscope because...
A
If wavelength is short and wavelength of electron beam can be made quite small...
B
If wavelength is short and light given by electrons has very short wavelength
C
If magnification is high and electronic lens provides much higher magnification
D
If magnification is high and the electron microscope has a battery of lenses...
โ Correct Answer: A - If wavelength is short and wavelength of electron beam can be made quite small...
๐ Step-by-Step Solution & Conceptual Rationale:
Resolution is inversely proportional to wavelength; electrons have much shorter de Broglie wavelengths than photons of visible light, allowing for higher resolution.
Sample Question 3
Physics
Easy • General Knowledge
On the Moon, astronauts inflate a rubber balloon with hydrogen gas and release it at a height of 2 meters. The balloon will:
A
Fall down
B
Go upwards
C
Remain at the height of 2 meters
D
First go up and finally come down
โ Correct Answer: A - Fall down
๐ Step-by-Step Solution & Conceptual Rationale:
Since the Moon has no atmosphere, there is no air displacement or buoyant force to make the balloon float; gravity will cause it to fall.
Sample Question 4
Physics
Easy • General Knowledge
Nights are cooler in the deserts because:
A
Sand radiates heat less quickly as compared to the earth
B
Sand radiates heat more quickly as compared to the earth
C
The sky is generally clear
D
The sky is generally cloudy
โ Correct Answer: B - Sand radiates heat more quickly as compared to the earth
๐ Step-by-Step Solution & Conceptual Rationale:
Sand has a low specific heat capacity and high emissivity, meaning it absorbs heat rapidly during the day and loses it just as quickly at night.
Sample Question 5
Physics
Easy • General Knowledge
If there were no atmosphere, what would be the colour of sky?
A
White
B
Black
C
Blue
D
Red
โ Correct Answer: B - Black
๐ Step-by-Step Solution & Conceptual Rationale:
The sky appears blue due to the scattering of sunlight by atmospheric gases (Rayleigh scattering); without air, no scattering occurs, leaving the sky dark.
Sample Question 6
Physics
Easy • General Knowledge
Ice skating can be used to demonstrate that when ice is under pressure, its:
A
Melting point is lowered
B
Melting point is raised
C
Melting point remains unchanged
D
Coefficient of friction with metal is reduced
โ Correct Answer: A - Melting point is lowered
๐ Step-by-Step Solution & Conceptual Rationale:
This phenomenon (regelation) allows a thin layer of water to form under the skate blade, acting as a lubricant.
Sample Question 7
Physics
Easy • General Knowledge
Who was the first to measure earthโs radius?
A
Galileo
B
Copernicus
C
Ptolemy
D
Eratosthenes
โ Correct Answer: D - Eratosthenes
๐ Step-by-Step Solution & Conceptual Rationale:
The Greek mathematician Eratosthenes calculated the Earth's circumference and radius with remarkable accuracy around 240 BCE.
Sample Question 8
Physics
Easy • General Knowledge
Light travels in:
A
Longitudinal waves
B
Transverse waves
C
Both of the above
D
None of above
โ Correct Answer: B - Transverse waves
๐ Step-by-Step Solution & Conceptual Rationale:
Light is an electromagnetic wave where the electric and magnetic fields oscillate perpendicular to the direction of wave travel.
Sample Question 9
Physics
Easy • General Knowledge
Ozone layer prevents which of the radiation from entering the atmosphere?
A
Infra-red
B
Ultraviolet
C
X-rays
D
Gamma rays
โ Correct Answer: B - Ultraviolet
๐ Step-by-Step Solution & Conceptual Rationale:
The ozone layer in the stratosphere absorbs approximately 98% of the Sun's medium-frequency ultraviolet light.
Sample Question 10
Physics
Easy • General Knowledge
Due to air pollution there is a gradual warming up of air. This is called:
A
Photosynthesis
B
Green house effect
C
Air heating
D
Air pollution
โ Correct Answer: B - Green house effect
๐ Step-by-Step Solution & Conceptual Rationale:
The trapping of the sun's warmth in the lower atmosphere due to greenhouse gases is the driver of global warming.
