The Flavivirus causes yellow fever, and it's transmitted when an infected mosquito bites you. Mosquitoes become infected with the virus when they bite an infected human or monkey. The disease cannot be spread from one person to another.
Q2. The coordination number of AB having rock salt geometry is
Answer : Option C
Explaination / Solution:
NaCl has rock salt structure. Coordination No. is 6.
Q3. What does a point below a PPC show
Answer : Option C
Explaination / Solution:
A PPF graph shows the maximum production level for one commodity for any production level of the other commodity. A point below the curve signifies inefficiency.
Q4. The order of screening effect of electrons of s, p, d and f orbitals of a given shell of an atom on its outer shell electrons is:
Answer : Option B
Explaination / Solution:
Screening effect order follows s>p>d>f, this due to the nature of the orbitals involved. s-orbitals are least diffused and the two electrons in s-orbitals provide greatest shielding of the nuclear charge to the outermost electron. The diffused character increases in the order p>d>f. f-orbitals are so diffused that fourteen electrons inside them provide virtually no screening of the nuclear charge.
Q5. What happens to TR when MR is decreasing but remains negative
Answer : Option D
Explaination / Solution:
No Explaination.
Q6. Which of the following gases is not a green house gas?
Answer : Option C
Explaination / Solution:
CO is not a green-house gas?
Q7.
A spray can containing a propellant gas at twice atmospheric pressure (202 kPa) and having a volume of 125 is at 22C. It is then tossed into an open fire. When the temperature of the gas in the can reaches 195C, what is the pressure inside the can? Assume any change in the volume of the can is negligible.
Answer : Option C
Explaination / Solution:
P∝TP1P2=T1T2P2=468×202295=320KPa
Q8. An atom of an element contains 29 electrons and 35 neutrons. The number of protons are:
Answer : Option B
Explaination / Solution:
In a atom no. of protons = no. of electrons i.e. P = E while this is not true in case of ions.
So number of protons in given atom is 29.
Q9. Compute the coefficient of correlation of the following score of A and B
Answer : Option C
Explaination / Solution:
Q10. Who conducts the periodical sample survey for estimating the poverty line in India?
Answer : Option D
Explaination / Solution:
The National Sample Survey Office (NSSO) headed by a Director General is responsible for conduct of large scale sample surveys in diverse fields on All India basis. Primarily data are collected through nation-wide household surveys on various socio-economic subjects, Annual Survey of Industries (ASI), etc. Besides these surveys, NSSO collects data on rural and urban prices and plays a significant role in the improvement of crop statistics through supervision of the area enumeration and crop estimation surveys of the State agencies. It also maintains a frame of urban area units for use in sample surveys in urban areas.
