• It is used when connected to a computer network that uses the Internet Protocol for communication.
• An IP address serves two main functions:
  • host or network interface identification
  • location addressing.

CONCEPT:

Force:

• The interaction which after applying on a body changes or try to changes the state of rest or state of motion is called force.
• It is denoted by F. The SI unit of force is Newton (N).

Force (F) = Mass (m) × acceleration (a)

• If more than one force is acting on a body, then the effect on the body is due to the net force.
• A stationary object on which no force is acting remains stationary.
• An object in motion continues to move with the same speed and direction when no force is acting on the object. This is Newton’s first law of motion. 

​CALCULATION:

Given:

Force = 20 N

Acceleration (a) = 2 m/s2

⇒ Force (F) = m a 

⇒ m = F/a = 20/2 = 10 kg.

So, option 4^th is correct.

The correct answer is Desert Climate.
