Question 1179

Which of the following pairs is incorrect ? (A) Roentgen : X-ray (B) Newton : Law of gravitation (C) Faraday : Diffusion of gases (D) Pasteur : Bacteriology

ARoentgen : X-ray

BNewton : Law of gravitation

CFaraday : Diffusion of gases

DPasteur : Bacteriology

Show answer

C. Faraday : Diffusion of gasesExplanation: The incorrect pair is Faraday : Diffusion of gases. The diffusion of gases was studied and explained by Thomas Graham, not by Michael Faraday. Graham’s Law states that the rate of diffusion of a gas is inversely proportional to the square root of its density or molar mass. On the other hand, Michael Faraday is famous for his work on electromagnetism and electrolysis. The other pairs are correctly matched with their discoveries.

Question 1178

What is the unit for measuring the intensity of sound ?

ADecibel

BCoulomb

CHenry

DHertz

Show answer

A. DecibelExplanation: The intensity of sound is measured in decibels (dB). The decibel is a logarithmic unit that expresses the ratio of a sound’s intensity compared to a reference level (usually the faintest sound the human ear can detect, known as the threshold of hearing). The higher the decibel value, the louder the sound. For example, normal conversation is around 60 dB, traffic noise is about 80–90 dB, and sounds above 120 dB can cause pain or hearing damage.

Question 1176

In our country National Integration Day is celebrated on :

A31st October

B30th January

C28th February

D19th of November

Show answer

D. 19th of NovemberExplanation not yet available.

Question 1175

What is the other name for Vitamin B2 ?

AHaemoglobin

BDextrose

CThiamine

DRiboflavin

Show answer

D. RiboflavinExplanation: Vitamin B2 is also known as Riboflavin. It is a water-soluble vitamin that plays a vital role in the body’s energy production and cellular function. Riboflavin acts as a coenzyme in the metabolism of carbohydrates, fats, and proteins, helping to convert food into energy. It is also essential for maintaining healthy skin, eyes, and nerve functions. A deficiency of Vitamin B₂ can lead to cracked lips, sore throat, and inflammation of the tongue (a condition known as ariboflavinosis).

Question 1174

Which of the following countries is not a member of BRICS ?

AIndia

BBrazil

Question 1173

Who wrote 'Aranyer Adhikar' ?

ABibhuti Bhusan Bandyopadhyay

BMahasweta Devi

CMahadevi Barma

DAnurupa Devi

Show answer

B. Mahasweta DeviExplanation not yet available.

Question 1172

The speed of light will be minimum while passing through :

AGlass

BVacuum

CAir

DWater

Show answer

A. GlassExplanation: The speed of light is maximum in a vacuum (approximately 3 × 10⁸ m/s) and decreases as it passes through denser media. Among the given options — vacuum, air, water, and glass — light travels slowest in glass because glass has the highest refractive index (around 1.5). The greater the refractive index, the slower the light travels. This slowing down of light causes refraction, or bending of light, when it passes from one medium to another.

Question 1171

Which year was declared as International Year of Physics :

A2011

B2012

C2005

D2006

Show answer

C. 2005Explanation not yet available.
