    When the material is cooled down under its critical temperature, which of the superconductor attains accidentally zero?

    Solutions

    The correct answer is Resistance.

    Key Points

    • When a material is cooled below its critical temperature, it undergoes a phase transition and can become a superconductor, exhibiting zero electrical resistance.
    • In a superconducting state, the material allows for the flow of electric current without any energy loss due to resistance.
    • The property of zero electrical resistance is not accidental but rather a defining characteristic of superconductors.
    • Once a material reaches its critical temperature, it transitions into a superconducting state, and its electrical resistance drops abruptly to zero.

    Additional Information

    • Different materials have different critical temperatures. In conventional superconductors, such as elemental metals like mercury or lead, the critical temperatures are generally very low, typically below a few Kelvin (Kelvin is the unit of temperature used in scientific measurements). For example, mercury has a critical temperature of around 4.2 Kelvin.
    • In recent decades, high-temperature superconductors (HTS) have been discovered, which have critical temperatures above the boiling point of liquid nitrogen (77 Kelvin or -196 degrees Celsius).
    • HTS materials, typically copper oxides or iron-based compounds, can exhibit superconductivity at relatively higher temperatures.

  • Question 4/10
    1 / -0.33

    Motion of an object is __________ if its velocity is constant.

    Solutions

    The correct answer is uniform.

    Key Points

    • It is known as uniform motion when an object moves in a straight path as direction remains constant at a constant speed.
    • This indicates that the body's velocity stays constant as it travels the same distance in the same amount of time.

    Additional Information

    Non-Uniform Motion:

    • When an object travels at varying speeds and does not cover the same distance in a constant amount of time.

    Speed:

    • Speed is a change in an object's location in any direction.
    • Speed is also defined as the ratio of distance to the amount of time it took to cover that distance. 

    Direction:

    • Direction is characterized as the course that anything follows. 
    • The route that must be taken to go to a particular location. 
    • The direction in which something is beginning to take shape, or the direction you are facing.

    An Element has Atomic number 17 and Mass number 36, then number of neutrons present in it?

    Solutions

    The correct option is 19.

    Key Points

    • The mass number is defined as the sum of the total number of protons and neutrons present in the nucleus of an atom. Protons and neutrons are also called nucleons.
    • The atomic number is defined as the total number of Protons present in the nucleus of an atom.
    • Mass Number ( Protons + Neutrons) - Atomic number (Protons) = Neutrons.
    • Therefore Neutrons present in the above-given data is 36 - 17 = 19.
    • Protons and neutrons are present in a small nucleus at the centre of the atom.

    Additional Information

    • 17 is the Atomic number of Chlorine (Cl).
    • Chlorine belongs to group 17 and p-block.

    Which of the following statements is correct regarding the Industrial Policy resolution 1956?

    I. This resolution formed the basis of the Second Five Year Plan.

    II. This policy was used for promoting industry in backward regions.

    Solutions

    Te correct answer is Both I and II.

    Key Points

    The Industrial Policy Resolution (IPR) 1956

    • Adopted to achieve the aim of a socialist state with the government controlling the major strategic industries of the economy.
    • According to this resolution, industries were classified into the following three categories:
      • Category 1: Those industries that were established and owned exclusively by the public sector.
      • Category 2: Those industries in which the public sector would perform the primary role while the private sector would play the secondary role i.e., the private sector supplements the public sector In these industries and new units could be set up only by the public sector.
      • Category 3: Those industries that are not included in Category 1 and Category 2 were left to the private sector.
      • The government kept indirect control of the industries in the private sector through the policy of industrial licensing.

    Additional Information

    • Highlights of IPR 1956:
    • In order to initiate a new industry or expand existing capacity, private entrepreneurs were supposed to obtain licenses from the government.
    • Licensing, imposition of the tax, tax exemptions, and subsidies were used by the government:
      • to regulate private industries.
      • bring about a reduction in regional disparities in industrial development. 
      • to keep a check on the production of goods that are socially undesirable.
    • Hence, the government fully controlled the private sector either directly or Indirectly through the IPR 1956.
