Question Discussion & Solution

• The Juvenile Justice Act of 2015 is an amendment to the Juvenile Justice Act, 2002.
• It provides for the trial of children in the age group 16-18 years as adults under circumstances involving heinous crimes.
• The act has defined a child as someone who is below the age of 18.
• Minimum Punishment - Seven years.
• However, the act doesn't make it mandatory to try all children in the age group of 16-18 years as adults.

The relation among given numbers is that every number is the sum of the squares of the digits of the previous number:

936 → 9² + 3² + 6² = 81 + 9 + 36 = 126

126 → 1² + 2² + 6² = 1 + 4 + 36 = 41

41 → 4² + 1² = 16 + 1 = 17

17 → 1² + 7² = 1 + 49 = 50

50 → 5² + 0² = 25

25 → 2² + 5² = 4 + 25 = 29

The correct answer is Archimedes' principle.

Concept:

Archimedes principle:

the principle of Archimedes states “When a body is immersed in a liquid, an upward thrust, equal to the weight of the liquid displaced, acts on it.”

Thus, when a solid is fully immersed in a liquid, it loses weight which is equal to the weight of the liquid it displaces.

i.e., \(Apperent\;weight = actual\;weight - buoyant\;force = mg - \rho gV\)

where m is mass of the object, ρ is the density of the fluid

Hence if there is no gravity, there is no Upward Thrust.

The upward force applied to the object is called the buoyant force.

Here,

ρ = density of liquid

g = acceleration due to gravity

V = volume of liquid displaced by the object

Explanation:

Archimedes’ principle, a physical law of buoyancy states that any body completely or partially submerged in a fluid (gas or liquid) at rest is acted upon by an upward, or buoyant, force the magnitude of which is equal to the weight of the fluid displaced by the body.

Hence floating of the ship is based on Archimedes principle:

Key Points

A binary tree is a tree data structure in which each node has at most two child nodes.

The number of subtrees of a node is called the degree of the node. In a binary tree, all nodes have degrees o, 1, and 2. 

The degree of a tree is the maximum degree of a node in the tree. A binary tree is of degree 2. The number of nodes of degree 2 in Tis "n-1".

Hence the correct answer is n-1.

The correct answer is Nahargarh Fort.

Key Points

• Nahargarh Fort:
  • It was built by the Kachwaha dynasty's Sawai Jai Singh in 1734 AD.
  • It is also known as Sudarshangarh Fort, which is the original name of Fort.
  • Its other names are- Jaipur's Crown, Palace's Fort, and Meethadi's Fort.
  • Sawai Madho Singh 2nd built 9 palaces for his 9 Paswan.
  • The name of Palaces are Suraj Prakash, Khushhal Prakash, Jawahar Prakash, Lalit Prakash, Chand Prakash, Anand Prakash, Lakshmi Prakash, Phool Prakash and Basant Prakash.
  • These Palaces were built in Victorian Style.

Additional Information

• Mawatha Lake is Situated In Amer Fort. 
  • it was built by Mirza Jai Singh in 1664 AD.
