The Correct Answer is Magnetic Force.

• Magnetic resonance imaging ( MRI) is one of the most popular medical imaging methods used in the world at many diagnostic centers.
• These MRI scanners use strong magnetic fields, gradients of the magnetic field, and radio waves to produce images of the organs inside the body.
• The magnetic force is a component of the electromagnetic force, one of nature's four basic forces, which is induced by charge movement.
• There would be a magnetic force of attraction between two objects containing charge in the same direction of motion, while objects in charge traveling in opposite directions have between them a repulsive force.

Key Points

 The process of converting a vector graphic to a bitmap is also known as rasterizing.

When you export a file to a bitmap file format, such as TIFF, JPEG, CPT, or PSD, the same bitmap conversion options are available.

Hence the correct answer is rasterization.

Additional Information

• Quantization, involved in image processing, is a lossy compression technique achieved by compressing a range of values to a single quantum value. When the number of discrete symbols in a given stream is reduced, the stream becomes more compressible.
• pixelization is the deterioration of a low-resolution image caused by a lack of enough pixels to render an image smoothly.
• The sampling rate determines the spatial resolution of the digitized image, while the quantization level determines the number of grey levels in the digitized image.

The given figure:

When we will unfold the paper for the first time, we will get the shapes on the upper half that is vertically rotated by 180° as shown below

Again, when we will unfold the paper for the second time we will get similar shapes on the lower half of the paper as the shapes are horizontally symmetrical. The paper will look like the figure below:

Hence, "option 4" is the correct answer

Hence, X is in North-west of C.

The correct answer is option 4.

Concept:

Phreaking is the oldest phone hacking technique used by hackers to make free calls.

Phreaking:

• A phreak is someone who breaks into the telephone network illegally, typically to make free long-distance phone calls or to tap phone lines. The term is now sometimes used to include anyone who breaks or tries to break the security of any network.
• Phreaking is a slang term coined to describe the activity of a culture of people who study, experiment with, or explore telecommunication systems, such as equipment and systems connected to public telephone networks.

Hence the correct answer is Phreaking.

The correct answer is Anaji Chauhan.

• The Anasagar lake was built by  Anaji Chauhan.
  • Ana Sagar Lake is an artificial lake.
  • It is one of Ajmer's most popular lakes and one of India's largest lakes.

Key Points

• Anaji Chauhan
  • The Anasagar lake was built by  Anaji Chauhan.
  • The lake was founded by the grandfather of Prithivi Raj Chauhan, King Anaji Chauhan between 1135 -1150.

Important Points

• The Baradari or pavilions were built by Shahjahan in 1637 and Daulat Bagh Gardens by Jehangir.

Additional Information

• Prithvi Raj Chauhan
  • Prithviraj III, popularly known as Prithviraj Chauhan or Rai Pithora was a king from the Chahamana (Chauhan) dynasty.
  • Prithviraj Raso is purported to be written by his court poet Chand Bardai.  
  • It gives a detailed description of Prithviraj Chauhan.
