Question Discussion & Solution

Running, Swimming, Dancing requires some body movement from one place to other.

While, Breathing does not require movable body movement.

Hence, Breathing is the correct answer.

Given: Sportspersons, Shooters, Swimmers

Logic: All shooters and swimmers are sportspersons but shooters and swimmers have no common relation.

Hence, option (2) is the correct answer.

A constitution is a statement of the basic principles and laws of a nation.

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 option 4) i.e. All of the above

CONCEPT:

• Magnetic field: The region around a magnet where its influence is experienced is called the magnetic field.
  • The visual representation of the magnetic field is called magnetic field lines.

​

• ​Properties of magnetic field lines:
  1. ​​The field lines start from the north pole and end at the south pole.
  2. The field lines are crowded where the magnetic field is the strongest.
  3. The field lines form continuous curves.
  4. The field lines do not intersect.

EXPLANATION:

• The magnetic field is strongest near the poles. Since magnetic field lines start and end at poles, they converge towards the region of strong magnetic force.
• Two magnetic field lines cannot intersect. If they did, at the point of intersection, the magnetic field will have two directions - which is not possible.
• The magnetic field lines have direction as they are represented as flowing, though no actual movement occurs. So, they do not move.

Therefore, all the given statements are true.
