Question 84

UKPSC Combined Upper Subordinate Service 2021• General Studies

Remote Sensing uses which of the following in its applications ?

  1. AOption (a)

    Electric waves

  2. BOption (b)

    Sonar waves

  3. COption (c)

    Gamma rays

  4. DOption (d)

    Electromagnetic waves

View answer & explanation

Correct answer

Answer: (d)D.

Electromagnetic waves

Why this answer is correct

The correct answer is Electromagnetic waves.

Key Points 

  • The waves used in common TV remote control are Infrared Rays.
  • Infrared (IR), sometimes called infrared light, is electromagnetic radiation (EMR) with wavelengths longer than those of visible light.
  • Infrared Rays are Electromagnetic waves.
  • It is therefore invisible to the human eye.
  • IR is generally understood to encompass wavelengths from the nominal red edge of the visible spectrum around 700 nanometers (frequency 430 THz) to 1 millimetre (300 GHz) (although the longer IR wavelengths are often designated rather as terahertz radiation).
  • Black-Body Radiation from objects near room temperature is almost all at infrared wavelengths.
  • As a form of electromagnetic radiation, IR propagates energy and momentum, with properties corresponding to both those of a wave and of a particle, the photon.

 Additional Information 

  • An X-ray, or X-radiation, is a penetrating form of high-energy electromagnetic radiation. Most X-rays have a wavelength ranging from 10 picometers to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz and energies in the range 124 eV to 124 keV.
  • Ultraviolet (UV) is a form of electromagnetic radiation with a wavelength from 10 (with a corresponding frequency around 30 PHz) to 400 nm (750 THz), shorter than that of visible light, but longer than X-rays. UV radiation is present in sunlight and constitutes about 10% of the total electromagnetic radiation output from the Sun. It is also produced by electric arcs and specialized lights, such as mercury-vapour lamps, tanning lamps, and black lights.
  • A Gamma-ray, or gamma radiation, is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei. It consists of the shortest wavelength electromagnetic waves and so imparts the highest photon energy.

Correct answer

Answer: (d)D.

A type of agriculture (cultivation)

Why this answer is correct

The correct answer is A type of agriculture (cultivation).

Key Points 

Jhum cultivation:

  • Also called Slash and Burn Agriculture is a form of crop-growing farming activity.
  • In the North-East states of India, Agriculture is primarily based on Jhum cultivation.
  • Britishers wanted tribal groups or jhum cultivators to settle down and become peasant cultivators.
  • In fact, jhum cultivators who took to plough cultivation often suffered, since their fields did not produce good yields.
  • So the jhum cultivators in north-east India insisted on continuing with their traditional practice.

  4. DOption (d)

    Semi-conductor

View answer & explanation

Correct answer

Answer: (c)C.

Conductor

Why this answer is correct

The correct answer is Conductor.

Key Points

Concept:

MaterialProperties
Conductor- A conductor is a type of material that allows the flow of an electrical current in one or more directions. It has very low resistance and hence low resistivity.
Insulator- An insulator is a type of material that prevents any electric current from flowing through it. It has very high resistance ideally infinite resistance.
Semiconductor- A semiconductor is a crystal material whose ability to conduct electricity rises as its temperature goes up. That is, it sometimes acts as a conductor and sometimes as an insulator.
Resistor- A resistor is a device used to produce resistance in an electronic circuit

Additional Information

  • A conductor having some appreciable resistance is called a Resistor.
  • Appreciable resistance means capable of being perceived or measured.
  • In other words, all conductor produce some resistance but it is negligible under normal condition.

  1. AOption (a)

    Air

  2. BOption (b)

    Water

View answer & explanation

Correct answer

Answer: (c)C.

Vacuum

Why this answer is correct

The correct answer is Vaccum.

Key Points

Light:

  • Light is a form of energy, which produces the sensation of vision in our eyes.
  • Light travels faster in vacuum.**
  • The objects around us reflect light. The reflected light reaches our eyes and make that thing visible to us.
  • Luminous objects like Sun, stars, electric bulbs etc have their own light and they are considered a source of light.
  • Non Luminous objects are those objects which do not have their own light but reflect the light coming from some source.
  • Light travels in a straight line in a given medium.

Additional Information

  • Transparent object: The object that allows light to pass through them or the objects across we can see are transparent objects. Examples: Glass, Water.
  • Translucent object: The object that partially allows light to pass through them are translucent objects. Example:  Filter Paper.
  • Opaque object: The object across which light cannot pass are called opaque objects, for example, cardboard, books, etc.

Question 88

UKPSC Combined Upper Subordinate Service 2021• General Studies

Which among the following animal is called as - "Ploughers of the soil" ?

  1. AOption (a)

    Earthworm

  2. BOption (b)

    Snake

  3. COption (c)

    Frog

  4. DOption (d)

    None of these

View answer & explanation

Correct answer

Answer: (a)A.

Earthworm

Why this answer is correct

The correct answer is Earthworm.

Key Points

Earthworms are useful in several ways for farmers-

  • Earthworms make the soil porous by digging burrows in the soil. Hence they are called Friends of the Farmers.
  • The nitrogenous wastes and other waste products of the earthworms form food for plants. This process of increasing the fertility of the soil by earthworms is called Vermicomposting.
  • Some tribals in India use earthworms as medicine to cure jaundice, piles, diarrhoea, bladder stones, etc.
  • The earthworms reduce both the acidity and alkalinity of the soil and create optimum conditions for plant growth.
  • The density of earthworms in the soil is considered to be a good indicator of healthy soil because they increase the soil's water-holding capacity and moisture content.

Thus, Earthworms are known as "The True Friends of the farmers ' or 'The Natural ploughers.

Additional Information

Different organisms use different types of organs to remove excreta.

  • Unicellular Animals / Amoeba – Diffusion through the surface of the body.
  • Platyhelminthes/ Flatworms – Flame cells
  • Roundworms/Earthworms – Nephridia
  • Arthropods/ Cockroaches – Malpighian tubules
  • Crustaceans / Prawns – Antennal glands / Green Glands
  • Vertebrates – Kidney
