Ans:
Sun Temple Konark
Explanation :
Konark Sun Temple is a 13th century Sun Temple, at Konark, in Odisha. It was constructed from oxidized and weathered ferruginous sandstone by King Narasimhadeva I of the Eastern Ganga Dynasty.
[47] Which among the following is used to dilute oxygen in the gas cylinders used by divers?
A.
ton
B.
Argon
C.
Helium
D.
Neon
Ans:
Helium
Explanation :
Helium is used to dilute the oxygen and nitrogen to reduce these affects. Helium is the gas of choice to use because it is an inert gas, is thinner, therefore more compressible than air, and its narcotic properties are negligible in comparison to nitrogen.
[48] Which one of the following does not form oxy-acid?
A.
Sulphur
B.
Chlorine
C.
Nitrogen
D.
Fluorine
Ans:
Fluorine
Explanation :
Fluorine cannot form oxy-acid because fluorine is more electronegative than oxygen. For oxygen to bind, it must be a Positively charged ion.
[49] The release of which of the following into ponds and wells helps in controlling mosquitoes?
A.
Snail
B.
Crab
C.
Dogfish
D.
Gambusia fish
Ans:
Gambusia fish
Explanation :
The Gambusia fish, also known as mosquito-fish, feeds on the larvae of mosquitoes. So it helps in controlling their population. Mosquito-fish were introduced directly into eco-systems in many parts of the world as a bio-control to lower mosquito populations which in turn negatively affected m y other species in each distinct bioregion.
[50] The ambient air is stable when the ambient lapse rate is -
A.
Neutrally stable
B.
Hyper-adiabatic
C.
Sub-adiabatic
D.
Super-adiabatic
Ans:
Sub-adiabatic
Explanation :
If the environmental lapse rate is greater than - 5.5 K/km then there is some small amount of vertical turbulence and the atmosphere is said to be stable. It is also referred to as being sub-adiabatic.
