Question Discussion & Solution

Preparing the family tree using the following symbols,

Given:

Mahendra is the son of Naman, who is the brother of Reema’s mother.

1) Mahendra is the son of Naman.

2) Naman is the brother of Reema’s mother.

We can draw following Family Tree from the information given above:

Hence, the Mahendra is the "Cousin" of Reema.

Joule is the SI unit of Energy.

Similarly,

Pascal is the SI unit of pressure.

Hence, pressure is the correct answer.

Additional Information 

* S.I Unit of Resistance is the Ohm.

* S.I Unit of Energy is Joule.

* S.I Unit of Volume is the Cubic meter.

* S.I Unit of Force is Newton.

* S.I Unit of Area is the Square meter.

* S.I Unit of Temperature is Kelvin.
Important Points 

There is a total of 9 S.I units.

1. 7 of them are fundamental units.

2. 2 of them are Supplementary units.

The correct answer is Udaipur.

• Gulab Bagh (also known as Sajjan Niwas Garden) is located in Udaipur.

Key Points

• Gulab Bagh:
  • It is located in Udaipur, Rajasthan.
  • It is the largest garden in Udaipur.
  • The garden is named so because of the abundance of roses and the innumerable varieties of it.
  • It was constructed by Maharana Fateh Singh in 1887.
  • It was earlier known as Sajjan Niwas Garden.
  • It also houses a museum called Victoria museum.
    • The museum is now called Saraswati Bhawan Library.
  • 

The correct answer is Switched Mode Power Supply.

• The full form of SMPS is Switched Mode Power Supply.

​Key Points

• SMPS or switched-mode power supply 
  • SMPS or switched-mode power supply is an electronic device that is used to convert AC to DC, AC to AC, DC to DC and DC to AC voltages. 
  • The circuit consists of a rectifier, voltage regulator transformer, and a filter. 
  • The input supply is turned On and Off by MOSFETs.
• Fundamentally, different types of circuits work with various kinds of power supplies such as SMPS.

Additional Information

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.
