Questions Related to production of electricity from solar energy

Multiple choice biology towards green energy solar power plant generation of electricity production of electricity from solar energy

Which of the following were released during accidental leakage in Chernobyl, the three-mile island?

  1. Low-level radiations

  2. Intermediate level radiation

  3. High level radiation

  4. No radiations were released
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Accidental leakage in Chernobyl nuclear power plant occur in April 26, 1986. Due to this high level radiation is get leaked out which cause long term health impact eg cancer and body deformation.

So, the correct option is 'High level radiation'.

Which of the following waste is present in coolant water from atomic reactors?

  1. Solid municipal waste

  2. Low-level radioactive waste

  3. High-level radioactive waste

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A nuclear reactor coolant is used to remove heat from the nuclear reactor core and transfer it to electrical generator which produce electricity. All the nuclear power plant use water as a coolant under high pressure. water is non radioactive material so there is low level of radioactive waste in coolant. 

So, the correct option is 'Low-level radioactive wastes'.

Which of the following reasons make nuclear waste an extremely potent pollutant?

  1. It causes mutations at a very high rate

  2. It is responsible for heating of Earths surface and atmosphere

  3. It is a very challenging task to provide safe disposal of radioactive wastes

  4. All of the above
Reveal answer Fill a bubble to check yourself
A,C Correct answer
Explanation

Nuclear waste is a very big problem in nuclear power plant due to the emission of harmful radiation which causes mutation in living organisms. Another problem facing in nuclear waste is the disposal of it because disposal is done in very deep in the oceans and there is the risk of leakage of radiation which is harmful to aquatic life also.

so correct options are 'it causes mutations at a very high rate ad it is a very chanllenging task to provide safe disposal of radioactive wastes'.

___________ was developed after World War II.

  1. Wind energy

  2. Solar energy

  3. Nuclear power

  4. Thermal power
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Nuclear power technology for electricity generation was developed and implemented in the post-World War II era, specifically in the 1950s. Wind, solar, and thermal power technologies have much older roots or were not the primary focus of post-war industrial development.

Problem associated with nuclear power plants is

  1. Emmission of hazardous waste

  2. Disposal of radioactive waste

  3. Thermal pollution

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A nuclear power plant is a thermal power station in which the heat source is a nuclear reactor. The heat is used to generate steam that drives a steam turbine connected to a generator that produces electricity.  The high temperature produced during a nuclear reaction causes thermal pollution thereby affecting the life forms. Radiations are continuously released by radioactive waste produced by these power plants that affect mankind for generations making it hazardous. Thus the correct answer is option D. 

Multiple choice biology towards green energy solar power plant generation of electricity production of electricity from solar energy

Assertion: X and Y rays are emitted by disintegration of atomic nuclei of radioactive elements Reason: Nuclear fall out is shown by radioactive elements

  1. If both the assertion and the reason are true and the reason is a correct explanation of the assertion

  2. If both the assertion and reason are true but the reason is not a correct explanation of the assertion

  3. If the assertion is true but the reason is false

  4. If both the assertion and reason are false

  5. If the assertion is false but reason is true
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The assertion is true because radioactive decay involves the emission of alpha, beta, and gamma rays. The reason is also true as radioactive elements do cause fallout, but the fallout itself is a consequence of the decay, not the mechanism that explains why the rays are emitted.

A non-ecofriendly source of energy is

  1. Tidal energy

  2. Wind energy

  3. Solar energy

  4. Nuclear energy
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Tidal energy, wind energy and solar energy are non-polluting sources of energy. They do not harm the environment. Nuclear energy is obtained by fission reaction carried out in nuclear reactors. Dumping of radioactive wastes generated during energy production using nuclear reaction causes serious environmental hazards making it non-ecofriendly. Thus the correct answer is option D.

The first disaster of nuclear reactor occurred at

  1. Trombay

  2. Narora

  3. Chemobyl

  4. TMI-2
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The first major nuclear reactor disaster occurred at Three Mile Island Unit 2 (TMI-2) in Pennsylvania, USA in 1979. This was a partial meltdown. Chernobyl (1986) happened later, and 'Chemobyl' appears to be a misspelling.
