Question Discussion & Solution

All except Yosemite National Park are in India. Yosemite National Park is in USA.

The correct answer is Hygrometer.

Key Points

• Hygrometer
  • A hygrometer is an instrument for measuring the relative humidity of the atmosphere.
  • The hygrometer was invented by Leonardo da Vinci.

Additional Information

• ​Barometer
  • A barometer is an instrument used to measure atmospheric pressure.
  • The barometer was invented by Torricelli.
• Hydrometer
  • A hydrometer is an instrument used to measure the specific gravity of liquids.
  • The hydrometer was invented by Nicholson.
• ​Anemometer
  • An anemometer is an instrument used to measure the velocity of wind and directions.
  • The anemometer was invented by Leon Alberti.

Concept:

• Electric current is the rate of flow electric charge or free Electrons in a definite direction through any section of wire. Its SI unit is ampere(A).
• The direction of the conventional current corresponds to the direction of positive charge which is from higher potential(positive) to lower potential(negative).

I = Q / t

I is current, Q is charge, t is time

Explanation:

Q = I t

So Charge is the product of current and time.

Unit of current is Ampere, and unit of time is an hour. 

So, Amount of charge or Quantity of electricity is Ampere-hour 

The correct answer is 1024 megabytes

The size of information in the computer is measured in Kilobytes (KB), Megabytes (MB), Gigabytes (GB), and Terabytes (TB).

• 1 Kilobyte (KB) = about 1 thousand bytes (or 1024 bytes to be precise)
• One Megabyte (MB) is about 1 million bytes (or about 1024 Kilobytes (KB)).
• One Gigabyte (GB) is about 1 billion bytes, or (1024 Megabytes MB).
• One Terabyte (TB) is about roughly 1 trillion bytes or 1024 gigabytes (GB).

The correct answer is Article 167.

• Article 167 of the Indian Constitution defines the duties of the Chief Minister.
