Question Discussion & Solution

The correct answer is 10.4%.

• Rajasthan is spread over approximately 10.4%  .
  • The state covers an area of 342,239 square kilometres.

​Additional Information

• Geography of Rajasthan
  • It is the largest Indian state by area and the seventh-largest by population.
  • Rajasthan is located on the northwestern side of India, where it comprises most of the wide and inhospitable Thar Desert (also known as the "Great Indian Desert") and shares a border with the Pakistani provinces of Punjab to the northwest and Sindh to the west, along the Sutlej-Indus river valley.
  • It is bordered by five other Indian states: Punjab to the north; Haryana and Uttar Pradesh to the northeast; Madhya Pradesh to the southeast; and Gujarat to the southwest.
  • Its geographical location is 23.3 to 30.12 North latitude and 69.30 to 78.17 East longitude.
  • The Tropic of Cancer passes through the southernmost tip of the state.

Important Points

Email bomb

It is an attack on your inbox that involves sending massive amounts of emails to your address. Sometimes these messages are complete gibberish, but more often they’ll be confirmation emails for newsletters and subscriptions.

Additional Information

Spoofing 

It is the act of disguising a communication from an unknown source as being from a known, trusted source. Spoofing can apply to emails, phone calls, and websites, or can be more technical, such as a computer spoofing an IP address, Address Resolution Protocol (ARP), or Domain Name System (DNS) server.

Smurf Attack

It is a form of a DDoS attack that causes packet flood on the victim by exploiting/abusing ICMP protocol. When deployed, large packets are created using a technique called “spoofing”. The phony source address that is now attached to these packets becomes the victim, as their IP is flooded with traffic. The small ICMP packet generated by the tool causes big trouble for a victim, hence the name Smurf.

Ping storm

It is a condition in which the Internet ping program is used to send a flood of packets to a server to  test its ability to handle a high amount of traffic or, maliciously, to make the server inoperable

Hence Option 1 is correct

Statement 1 and 2: correct

• OS allows the computer to manage its own resource such as memory, keyboard and printer

Statement 3: correct

• OS provides the user an easy to work user interface, so the user doesn’t have to learn a different UI every time.

Statement 4: correct

Concept:

Resistance: The property of electrical materials and electrical instruments that opposes the flow of current through them is called resistance.

It is denoted by R. The SI unit of resistance is the ohm (Ω).

Power: The rate of work done by an electric current is called power. It is denoted by P. The SI unit of power is the watt (W).

Power dissipation (P) is given by:

\(P=VI=\frac{V^2}{R}=I^2R\)

Where V is the potential difference across resistance, I is current flowing and R is resistance.

Calculation:

With R = 50 Ω, and V = 220 V, the power required by the bulb will be:

\(P=\frac{V^2}{R}=\frac{220\times 220}{50}\)

P = 968 W

As the total distance between A and G is equal to E and D i.e. 20 km. So BD = 20 – (10 + 1) = 9 Km.

Hence, the distance between B and D is 9 km
