Question Discussion & Solution

The correct answer is X-Ray.

• Electromagnetic (EM) radiation includes radiation via radio waves, microwaves, X-rays and gamma rays.

Key Points

• Electromagnetic (EM) radiation is a form of energy that is all around us and takes many forms.
• Electromagnetic (EM) radiation includes radiation via radio waves, microwaves, X-rays and gamma rays.
• Sunlight is also a form of EM energy.

​Additional Information

• ​EM radiation spans an includes a range of wavelengths and frequencies.
• This range is known as the electromagnetic spectrum.
• The EM spectrum is generally divided into seven regions:
  • Radio waves,
  • Microwaves,
  • Infrared (IR),
  • Visible light,
  • Ultraviolet (UV),
  • X-rays,
  • Gamma rays.

Important Points

• Radio waves have the longest wavelength.
• Gamma rays have the shortest wavelength.

Concept:

In magnetic compass, a magnetic needle which always directs the North-South direction.

• The compass is an instrument used for navigation and orientation that indicates position relative to the geographical directions (or points).
• Typically, a diagram called a compass rose displays the directions to the north, south, east, and west on the compass face.

Elements of Earth's Magnetic Field:

• The magnitude and direction of the magnetic field of the earth at a place are completely given by certain quantities known as magnetic elements.

Explanation:

Earth has its own magnetic field whose poles are

• Magnetic North is in Geographical South pole.
• Magnetic South is in Geographical North Pole.
• A compass needle is a bar magnet with a pointed north pole. It is attracted to the magnetic south pole.
• Hence magnetic needle points in North Direction (Magnetic South). 

• A mistake is essentially any programmer action that later shows up as an incorrect result during program execution
• A programmer may commit a mistake in almost any development activity; For example, during coding a programmer might commit the mistake of not initializing a certain variable or might overlook the errors that might arise in some exceptional situations such as division by zero in an arithmetic operation, both these mistakes can lead to an incorrect result

According to given conditions,

Clearly, the man is now facing West.

Hence, ‘West’ is the correct answer.

The correct answer is Camel.

Key Points

• The state animal of Rajasthan is Camel.
• Camel was adopted as the state animal of Rajasthan to control the decreasing number of camels in the state. 
• It was adopted in 2014 by the Rajasthan state government.

Additional Information

• State Bird: Great Indian Bustard.
• State Animal (Wildlife) - Chinkara
• State Flower: Rohida.
• Chinkara is also the official animal of Rajasthan.
• National Park: Sariska National Park, Ranthambore National Park, Desert National Park, and Keoladeo Ghana National Park.
• Geographical indication: Kota Doria, Kathputlis, Blue pottery, Molela, clay work, Sanganeri Hand Block Printing, Phulkari, Bikaneri Bhujia, Bagru hand block print, Thewa artwork, Makrana marble.
