41. For what is Mohs scale used? [S.S.C. Online CHSL (T-I) 23.01.2017(Shift-III)]

(a) To measure brightness of a substance
(b) To measure viscosity of a liquid
(c) To measure elasticity of a material
(d) To measure hardness of minerals

Correct Answer: (d) To measure hardness of minerals

Solution:The Mohs Hardness Scale is used as a convenient way to help identify minerals.

A mineral's hardness is a measure of its relative resistance to scratching, measured by scratching the mineral against another substance of known hardness on the Mohs Hardness Scale.

(a) Enrico Fermi
(b) Adolf Gaston Eugen Fick
(c) Sandford Fleming
(d) Benoit Fourneyron

Correct Answer: (c) Sandford Fleming

Solution:Sandford Fleming, a Canadian engineer, invented the Universal Standard Time.

Sir Sandford Fleming advocated the adoption of a standard time or mean time, as well as hourly variations from that according to established time zones.

(c) Alexey Pajitnov
(d) Ransom Eli Olds

Correct Answer: (b) Luigi Palmieri

Solution:In 1855 Italian scientist Luigi Palmieri designed a seismograph that consisted of several U-shaped tubes filled with mercury and oriented toward the different points of the compass.

48. Millions of years ago the Indian subcontinent was separated from the mainland by a large sea known as the: [S.S.C. Online CHSL (T-I) 14.10.2020 (Shift-I)]

(a) Aegina
(b) Prometheus
(c) Typhon
(d) Tethys

Correct Answer: (d) Tethys

Solution:Millions of years ago, the Indian subcontinent was separated from the mainland by a large sea known as the Tethys.

During the movement of the earth's crust, known as Continental Drift, it began moving northwards towards the mainland.

49. The maximum mass theoretically possible for a stable white dwarf star is known as: [S.S.C. JE Civil Exams 30.10.2020 (Shift-I)]

(a) Roche limit
(b) Chandrasekhar limit
(c) Rudolf limit
(d) Bose limit

Correct Answer: (b) Chandrasekhar limit

Solution:The Chandrasekhar Limit of 14 solar masses is the theoretical maximum mass a white dwarf star can have and still remain a white dwarf (though this limit does vary slightly depending on the metallicity).

50. The plate movements on earth are classified into _________________ types. [S.S.C. Online MTS (T-I) 12.07.2022 (Shift-III)]

(a) three
(b) two
(c) five
(d) six

Correct Answer: (a) three

Solution:The plate movements on Earth are classified into three types, which are:

Divergent boundaries: In this type of boundary, the plates move away from each other. This type of movement leads to the formation of rift valleys, mid-ocean ridges, and new crust formation.

Convergent boundaries: In this type of boundary, the plates move towards each other. This type of movement leads to the formation of mountains, subduction zones, and volcanic activity.

Transform boundaries: In this type of boundary, the plates move past each other in opposite directions. This type of movement leads to the formation of faults and earthquakes.
