Question Discussion & Solution

The correct answer is In 1976.

• In 1976 the Indian Postal and Telegraph Department issue a commemorative postage stamp in honour of Pandit Hiralal Shastri.

Key Points

• Pandit Hiralal Shastri 
  • ​​The Indian Posts and Telegraphs Department issued a commemorative postage stamp in November 1976 in honour of Pandit Hiralal Shastri.

​Additional Information 

• Pandit Hiralal Shastri ​
  • Hiralal Shastri was born at Jobner in Jaipur.
  • In 1929, Hiralal Shastri selected a remote and backward village Banasthali, Jaipur and founded 'Jeevan Kutir' there.
  • Here he trained a group of social workers and endeavoured to implement a programme of rural reconstruction.
  • In 1937 he joined Jaipur Rajya Praja Mandal and he was twice elected General Secretary and twice President of it.
  • In 1939 he led the Praja Mandal's Satyagraha for the achievement of civil liberties and suffered six-month imprisonment.
  • In 1947 he was appointed General Secretary of the All India States Peoples Conference.

The Logic here is as follows:

(1^st Number × 2^nd number) × 4 = 3^rd Number

In (6, 8, 192)

(1^st Number × 2^nd number) × 4

= (6 × 8) × 4

= 48 × 4

= 192 = 3^rd Number

Now check the all options,

Option (1) (12, 13, 263)

(1^st Number × 2^nd number) × 4

= (12 × 13) × 4

= 156 × 4

= 624 ≠ 3^rd Number

Option (2) (8, 11, 180)

(1^st Number × 2^nd number) × 4

= (8 × 11) × 4

= 88 × 4

= 352 ≠ 3^rd Number

Option (3) (11, 9, 396)

(1^st Number × 2^nd number) × 4

= (11× 9) × 4

= 99 × 4

= 396 = 3^rd Number

Option (4) (7, 5, 78)

(1^st Number × 2^nd number) × 4

= (7 × 5) × 4

= 35 × 4

= 140 ≠ 3^rd Number

Hence, the correct answer is "(11, 9, 396)".

The correct answer is Jaisalmer and Bikaner.

Key Points
Tropical Thorn Forest:

• These forests are found in Jaisalmer, Bikaner and Barmer.
• It comprises 6.25% of the forest in Rajasthan. 
• Rainfall varies from 0 to 25 cm. It is scanty in nature.
• Xerophytic vegetation is found in this forest. 
• Khejri, Rohida, and Jaal are prominent trees present in the Forest.

Additional Information

Concept:

• Potential Energy: The energy of an object obtained by doing work against the conservative forces like spring force and gravitational force is called potential energy.
• The Gravitational potential energy of an object at a height h from the ground is given as

P = mgh

The spring potential energy of spring when it is stretched x distance from its natural length is given as

 \(P = \frac{1}{2}kx^2\)

• Kinetic Energy: The energy obtained by an object by virtue of its motion is called kinetic energy.

\(K = \frac{1}{2}mv^2\)

K is kinetic energy, v is the speed of the object, m is the mass of the object.

• Mechanical Energy: The sum of potential energy and kinetic energy is called mechanical energy.

Explanation:

So, from the above concept, it is clear that total mechanical energy is the sum of potential energy and kinetic energy. 

So, the answer is the Sum of Kinetic Energy and Potential Energy.

The correct answer is ARP (Address Resolution Protocol)

Additional Information

• Address Resolution Protocol (ARP) is a protocol or procedure that connects an ever-changing Internet Protocol (IP) address to a fixed physical machine address, also known as a media access control (MAC) address, in a local-area network (LAN).
• The RARP is on the Network Access Layer and is employed to send data between two points in a very network. The client broadcasts a RARP request with an Ethernet broadcast address and with its own physical address. The server responds by informing the client its IP address.24
