Question Discussion & Solution

The correct answer is Tamil Nadu.

Key Points

•  Bharatnatyam:
  • ​Bharatnatyam Dance is considered to be over 2000 years old.
  • Several texts beginning with Bharata Muni's Natya Shastra (200 B.C.E to 200 C.E.) provide information on this dance form.
  • Bharatnatyam Dance is known to be Ekaharya, where one dancer takes on many roles in a single performance.

The correct answer is Memory.

Key Points

• The memory mapping process is handled by the virtual memory manager, which is the same subsystem responsible for dealing with the page file.
• Memory-mapped files are loaded into memory one entire page at a time.
• The page size is selected by the operating system for maximum performance. 

Additional Information

• A memory
  • It is just like a human brain.
  • It is used to store data and instructions. 
  • Computer memory is the storage space in the computer, where data is to be processed and instructions required for processing are stored.
  • The memory is divided into a large number of small parts called cells.
• Process
  • It is the instance of a computer program that is being executed by one or many threads.
  • It contains the program code and its activity.
  • Depending on the operating system, a process may be made up of multiple threads of execution that execute instructions concurrently.
• A computer file
  • It is a computer resource for recording data in a computer storage device.
  • Just as words can be written to paper, so can data be written to a computer file.
  • Files can be edited and transferred through the Internet on that particular computer system.
• Computer security
  • cybersecurity or information technology security is the protection of computer systems and networks from information disclosure, theft of or damage to their hardware, software, or electronic data, as well as from the disruption or misdirection of the services they provide.

1^st letter: increase by - 8, - 4, - 2, - 1

P - 8→ H - 4→ D - 2 → B - 1 → A

2^nd letter: second letter increase by + 2

K + 2→ M +2 → O + 2 → Q + 2 → S

3^rd letter: Decrease by - 1

R - 1→ Q – 1 → P - 1 → O – 1 → N

All are mammal except Lizard.

Concept:

• The laws dealing with ideal gases naturally called ideal gas laws, and the laws determined in the seventeenth century by Boyle's observational work and in the eighteenth century by Charles.
• The Boyles Law states that the gas pressure is inversely proportional to the gas volume for a given mass of gas stored at a constant temperature.
• Charles Law states that the gas volume is directly proportional to the gas temperature for a given fixed mass of gas stored at a constant pressure. 
• An ideal gas is a gas that follows the equation:

PV = nRT at all temperatures and pressure, where P = Pressure of the ideal gas. V = Volume of the ideal gas n = Amount of ideal gas measured in terms of moles 

R = Universal gas constant T = Temperature

Mole Concept -

•  The quantity one mole of a substance signifies 6.022 × 1023 number of particles of that substance which may be atoms, molecules, or ions.
• The quantity is a universal constant like Dozen, Gross, etc., and is known as Avogadro number, denoted by NA. after the scientist Amedeo Avogadro.
• Examples- In one mole of H2, there are 6.022 × 1023 molecules of hydrogen, and the number of atoms is 2 × 6.022 × 1023, as one molecule of hydrogen contains two-atom each.
• The mass of one mole of a substance is called its Molar Mass (M) or Atomic mass expressed in grams.
• The volume occupied by a mole of gas is 22.4 L at NTP, called its Molar Volume.
• The no. of moles (n) is calculated as =

The number of particles / Avogadro’s number.

To summarise, we can say, 

Calculation:

• The molar mass of 1 mole of H₂SO₄ is =

2 × 1 + 32 + 4 × 16 = 98g

• The molar mass of 1 mole of Silver, Ag is its molecular mass 108g.
• The molar mass of CO₂ is = 12 + 2× 16 = 44g.
• 44g of CO₂ means one mole.
• 1 mole of Oxygen weighs 16 + 16 = 32g.
• Hence, the highest mass is of 1 mole of Ag.
