Question Discussion & Solution

1 atm is equal to 760 torr.

• The atmospheric pressure(atm) is unit of the pressure within the atmosphere of Earth. 
• At sea level the Earth's atmospheric pressure is 1 atm.
• The torr is an absolute-scale which is unit of pressure.
• The unit took its name from Evangelista Torricelli, an Italian physicist and mathematician who invented the barometer theory in 1644.

The correct answer is Udaipur.

• Sorghum research centre has been established in Vallabhnagar Udaipur in Rajasthan.

Key Points

• Sorghum/Jowar is used as food grains.
• The highest Jowar production in the country is in Maharashtra.
• Whereas Rajasthan holds the fourth position in the country.
• Rajasthan has the highest production of Jowar in the central part.
• While Ajmer district ranks fifth in Jowar production.

Additional Information

• The major variety of Jowar in the state is PV-96.
  • Maximum Producing District - Nagaur, Ajmer, Pali.
  • Climate - Warm temperature is required.
  • Rainfall - 35 -150cm
• Alcohol and Beer are made from Sorghum.

The correct answer is option 3.

Concept:

A semaphore is a variable or abstract data type used to control access to a common resource by multiple threads and avoid critical section problems in a concurrent system such as a multitasking operating system.

Explanation:

Starvation is a problem that happens when high-priority processes continue to run while low priority processes are halted indefinitely. A continual stream of higher-priority processes in a densely loaded computer system can prevent a low-priority operation from ever receiving the CPU.

Indefinite blocking or starvation is a situation in which processes wait indefinitely within the semaphore. Indefinite blocking may occur if we remove processes from the list associated with a semaphore in LIFO (last-in, first-out) order.

Hence the correct answer is starvation.

Additional InformationCritical section:

 The critical section is the section of code in which processes access and write to shared resources such as common variables and files. Because processes run continuously, any process can be interrupted in the middle of its execution.

Hence, “21” will come next.

The correct answer is 23.3 N to 30.12 N.

Key Points

•  The total area of Rajasthan is 3,42,239 sq km.
• The Rajasthan geographical location
  • 23.3 N to 30.12 North latitude
  • 69.30 E to 78.17 East longitude

Additional Information

• Rajasthan is the largest state in India.
  • The Present Rajasthan was made on 1 November 1956.
  • In geographical knowledge, it was once a part of Gondwana land.
    • Gondwana used to be the southern part of the supercontinent Pangea.
  • Rajasthan's shape looks like an irregular Rhomboid or Rhombus.
