Question Discussion & Solution

The Correct answer is Uniform motion.

Key Points

• Motion​:
  • It is a phenomenon in which an object changes its position with respect to time.
  • All motions are relative to some frame of reference. 
  • There are two types of motion:
    • Uniform Motion
    • Non-uniform Motion
• Uniform motion:
  • If an object is traveling with uniform motion, it is moving in a straight line at a constant speed.
  • For example, An object falling at terminal velocity experiences the same air resistance as its weight.
  • Newton's first law can be used to explain the movement of objects traveling with uniform motion.
  • Newton's first law is a body that is at rest or moving at a uniform rate in a straight line will remain in that state until some force is applied to it.

​Additional Information

• Retarding motion: The Motion in which the speed of the body gradually decreases.
• Non-uniform motion: If a body covers unequal distances in equal intervals of time
• Non-linear Motion: Nonlinear motion is motion along a curved path; It is the combination of two components of motion' horizontal motion (without acceleration) vertical motion (under the acceleration of gravity).

 Hence, option 2 is the correct answer.

Concept:

Matter

• The thing which occupies space is called matter.
• The matter is made up of particles and based on the arrangement of particles matter has been classified into different states.
• The matter has 5 states, Solid, liquid, glass, Plasma, Bose - Einestine condensate.
• Solid, Liquid, and Gas are states of matter that we observe across our surroundings.
• The following table defines these three states.
   

The arrangement of particles in solid, liquid, and gas is shown in this diagram.

Explanation:

• The state of matter with a definite volume but no definite shape is liquid.
• The liquid gets itself in the shape of its container. This can be easily observed.
  • If we keep liquid in the jug it will be according to its shape.
  • The shape will change if the same liquid is poured into a glass.
• Though the volume of the liquid does not change. It will remain the same.

Therefore the correct option is liquid.

Arrow moves one, two, three, four, and five sequentially anticlockwise. The arrow head change in a sequence of filled circle → Filled arrow → Open arrow

Next figure is gap of five with open arrow. 

The correct answer is Hexadecimal.

Key Points

• The hexadecimal Number system Contains 16 digits.
• The base of this number system is 16.
• It comprises 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F.

Additional Information

• About Binary number system:
  • There are only 2 digits in the Binary system, which are 0 and 1.
  • The base of this number system is 2.
  • This number system is used by all digital computers to convert the data input from decimal to its binary equivalent.
• About Decimal number system:
  • It contains 10 digits.
  • It comprises 0,1,2,3,4,5,6,7,8,9.
  • The base of this number is 10.
• About Octal number system:
  • It contains 8 digits.
  • The base of this number is 8.
