In nature, almost all metals are found in solid state except mercury. Mercury is a metal that is found in a fluid state at normal temperature.

English chemist John Dalton (1766-1844) first proposed the modern atomic theory. John Dalton's theory is called modern because all the facts written about the atom were experimentally found to be correct. It has mainly five parts.

Argument I: This is strong because speed driving is one of the major causes of road deaths as per statistics.

Argument II: This is not strong because, speed driving is the cause of accidents.

So, only argument I is strong.

Only argument I is strong.

Argument I: Mental health is as important as physical health so to maintain the mental health of children they should counselled regularly. Hence, Argument I is strong.

Argument II: In statement it is clear to maintain mental health one should go for counselling

So argument II is not strong because it does not support the statement.

​The correct answer is Charles Babbage.

Key Points

• Charles Babbage is considered the father of computers.
• Charles Babbage invented the machine called the Analytical Engine, which is a model of today's computers. Since he was the first person who gave us the basic idea of computers, he is known as the 'father of computers.
• In 1837 the Analytical Engine contained an ALU (arithmetic logic unit), basic flow control, and integrated memory, hailed as the first general-purpose computer concept.
• Because of funding issues, this computer was not built while Charles Babbage was alive. However, in 1910 Henry Babbage, Charles Babbage's youngest son was able to complete a portion of the machine that could perform basic calculations.
• Although Babbage never completed his invention in his lifetime, his radical ideas and concepts of the computer are what make him the father of computing.

Additional Information

TCP stands for Transmission Control Protocol.

Key Points

• The Transmission Control Protocol (TCP) is a transport protocol built on top of IP that ensures packet delivery reliability.
• In Transmission Control Protocol communication, the two computers begin by establishing a connection via an automated process called a ‘handshake.’
  • Once this handshake is complete, the first computer will begin delivering data packets to the second.
• TCP addresses many of the issues that arise with packet-based messaging, such as missing packets, out-of-order packets, duplicate transmissions, and malformed packets.
• TCP communications specify the order in which data packets should be received and verify that they arrive in the correct sequence.
• TCP specifies that if a packet does not arrive (due to congestion in intermediary networks) it be resent.

Additional Information

• A server is a computer or system that across a network distributes resources, data, services, or programmes to other computers known as clients.
• A socket is one of the two ends of a two-way communication link between two networked programmes.
• The norms and customs of a group or a regular procedure are referred to as a protocol.

The correct answer is Man in the middle.

• Eavesdropping attack also referred to as Man in the middle attack is a major concern when comes to cyber security. 
• Man in the Middle Attack (MITM): A MITM attack is when a hacker secretly relays communication between two parties who believe they are communicating directly.
  • When emails are sent between two parties unless both parties use encryption the message is open and can be read by anyone who intercepts it.
  • It is a kind of email hacking.

Additional Information​ 

• Phishing is a fraudulent attempt to obtain sensitive information or data, such as usernames, passwords and credit card details.
• It is the act of disguising oneself as a trustworthy entity in electronic communication.
• Signs of phishing include:
  • Incorrect URLs
  • No signature or contact information
  • Too good to be true offer
  • Style inconsistencies 
  • Spelling, punctuation, or grammar errors
  • Attention-grabbing titles

The correct answer is "Joystick".

Key Points

• Plotter: A plotter is referred to as a type of printer. It is an output device. The main job of the plotter is to convert the user commands from a computer into line drawings on paper. It has one or more automated pens which help to draw the lines on the paper. 
• Speaker: The speaker is an output peripheral of the computer. If the user plays some audio or video files on the system, the sound comes out from the speaker.
  
• Projector: The projector is an output device. The projector is used for projecting images or video on the screen.
  
• Joystick: The joystick is referred to as an input peripheral. The joystick is mainly used for playing games in the computing system.
  

Thus the correct answer is "Joystick".

Additional Information

• The word computer is derived from the word compute. In the year 1833, English mechanical engineer Charles Babbage designed the first analytical engine. He is known as the father of the computer.
• In the beginning, computers are used for calculating large numbers and can only store a small amount of data.
• The software and the hardware parts of the computers are running together to execute the operations smoothly.
• Software is a set of instructions or programs given to the computers' hardware to perform a task. For example, system software (OS), application software( MS Office, Browser), and programming software(compiler).
• The hardware parts of the computer are tangible parts of the computer which collect the input (e.g. keyboard, mouse, scanner etc.), and process (e.g. C.P.U). It and display it to the respective output devices(e.g. monitor, printer etc.). Sometimes it stores the processed data in the memory.

The correct answer is Adobe Inc.

• Photoshop is a software program used extensively for image editing, graphic design, and digital art. Thus Adobe Inc company have the right to sell this software.
• Adobe Photoshop is a raster graphics editor developed and published by Adobe Inc. for Windows and macOS.
• It was originally created in 1988 by Thomas and John Knoll. Since then, the software has become the industry standard not only in raster graphics editing but in digital art as a whole.
• Photoshop can edit and compose raster images in multiple layers and supports masks, alpha compositing, and several color models including RGB, CMYK, CIELAB, spot color, and duotone.

Key Points

• Photoshop uses its own PSD and PSB file formats to support these features.
• Photoshop's naming scheme was initially based on version numbers. However, in October 2002, each new version of Photoshop was designated with CS plus a number.
• Photoshop was developed in 1987 by two brothers Thomas and John Knoll, who sold the distribution license to Adobe Systems Incorporated in 1988.
• Photoshop 1.0 was released on February 19, 1990, for Macintosh exclusively.
• On March 31, 1995, Adobe purchased the rights for Photoshop from Thomas and John Knoll for $34.5 million.

Using Rule 1 :
1st number × 2nd number = L.C. M. × H.C.F,
First number × Second number = HCF × LCM

Let the measured of the required angle be P degree.
Then, its supplement = 180 – P
Now use the formula,

3P + P180°
⇒ P = 45°

Let the two Trains pass after x hours,

then for Calcutta mail, we have

Distance travelled in x hours = 48x kms

Distance travelled after passing Bombay mail = 

Now, For Bombay Mail, we have

Distance travelled in x hours = 576Km

The Schottky also known as Schottky barrier diode or hot-carrier diode, is a semiconductor diode formed by the junction of a semiconductor with a metal. It has a low forward voltage drop and a very fast switching action. A silicon diode has a typical forward voltage of 600–700 mV, while the Schottky's forward voltage is 150–450 mV. This lower forward voltage requirement allows higher switching speeds and better system efficiency.

All the given vary with change in temperature. Their mathematical relation with temperature is given as:
→ ηi² = A₀T³.e(^-EGO/kT)
→ μ= T^-m ; m=2.5 for electrons and 2.7 for holes
→ σ = σ₀ [1+α(T-T_o)]
→ E_G(T) = E_G0 - βT

Hence, the correct option is (b).

Hence, the correct option is (D)

Hence, the correct option is (A)
