Activities like walking, climbing, pulling, pushing etc need  ____________.

  1. solar energy

  2. muscular energy

  3. wind energy

  4. mechanical energy


Correct Option: B
Explanation:

Activities like walking, climbing, pulling, pushing etc need Muscular energy.
Muscular energy is the conscious movement of energy along the lines of the body, drawing muscle to bone and connecting limbs to joints as the energy moves ever inward to the body's core.

Energy of an object by virtue of its position is called _____________.

  1. solar energy

  2. mechanical energy

  3. muscular energy

  4. potential energy


Correct Option: D
Explanation:

Energy of an object by virtue of its position is called Potential energy.
The potential energy is the type of energy, which a body possesses by virtue of its position is known as the potential energy. Transferable.

 Sum of potential energy and kinetic energy is called ______________.

  1. mechanical energy

  2. muscular energy

  3. solar energy

  4. wind energy


Correct Option: A
Explanation:

Sum of potential energy and kinetic energy is called Mechanical energy.
The mechanical energy of an object can be the result of its motion (i.e., kinetic energy) and/or the result of its stored energy of position (i.e., potential energy). The total amount of mechanical energy is merely the sum of the potential energy and the kinetic energy.

In India the most important source of energy is _______.

  1. Petroleum

  2. Coal

  3. Nuclear

  4. Hydro-electricity


Correct Option: B
Explanation:
In India the most important source of energy is Coal.
Coal is the largest source of electricity in India.
Thermal power is the "largest" source of power in India. There are different types of thermal power plants based on the fuel used to generate the steam such as coal, gas, and Diesel, natural gas. About 71% of electricity consumed in India is generated by thermal power plants.

________________  is obtained from the organic waste.

  1. Nuclear energy

  2. Solar energy

  3. Bio-gas

  4. Wind energy


Correct Option: C
Explanation:

Bio-gas is obtained from the organic waste.
Organic wastes are often disposed of with other wastes in landfills or incinerators, but since they are biodegradable , some organic wastes are suitable for composting and land application. Organic materials found in municipal solid waste include food, paper, wood, sewage sludge , and yard waste .

Which of the following is not the non-conventional sources of energy in India?

  1. Solar Energy

  2. Geo-Thermal Energy

  3. Thermal Energy

  4. Tidal Power


Correct Option: C
Explanation:

Thermal energy is not the non-conventional source of energy in India.
Thermal energy comes from a substance whose molecules and atoms are vibrating faster due to a rise in temperature. Heat energy is another name for thermal energy. Kinetic energy is the energy of a moving object. As thermal energy comes from moving particles, it is a form of kinetic energy.

The gas produced by decaying agricultural waste, plant residues, animal dung etc. in the absence of air, is called _____________.

  1. carbon di oxide

  2. bio gas

  3. nitrogen

  4. ozone gas


Correct Option: B
Explanation:

The gas produced by decaying agricultural waste, plant residues, animal dung etc. in the absence of air, is called Biogas.

Biogas is the mixture of gases produced by the breakdown of organic matter in the absence of oxygen. Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste. Biogas is a renewable energy source.

 The energy which a body possesses by virtue of being in motion is called _______________.

  1. potential energy

  2. muscular energy

  3. mechanical energy

  4. kinetic energy


Correct Option: D
Explanation:

The energy which a body possesses by virtue of being in motion is called Kinetic energy.
Kinetic energy is the type of energy, which a body possesses by the property of being in the motion. The potential energy is the type of energy, which a body possesses by virtue of its position is known as the potential energy.

 The energy available from bio gas can be converted into  ______.

  1. heat

  2. light

  3. electricity

  4. sound


Correct Option: C
Explanation:

Theoretically, biogas can be converted directly into electricity by using a fuel cell. However, this process requires very clean gas and expensive fuel cells. In most cases, biogas is used as fuel for combustion engines, which convert it to mechanical energy, powering an electric generator to produce electricity.

Which is the largest source of electricity in India?

  1. coal

  2. oil

  3. natural gas

  4. lignite


Correct Option: A
Explanation:

Coal is the largest source of electricity in India.
Thermal power is the "largest" source of power in India. There are different types of thermal power plants based on the fuel used to generate the steam such as coal, gas, and Diesel, natural gas. About 71% of electricity consumed in India is generated by thermal power plants.

Consider the following statements-
(a) Individual resources are owned privately by individuals.
(b) At present, petroleum is the only multipurpose fuel which is the most important source of thermal energy.
(c) We have abundance of hydro-electricity resources.
(d) Thermal power is not a permanent source of electricity as the coal, petroleum and natural gas deposits are exhausting

  1. Apsara

  2. Pokharan

  3. Koyana

  4. Kalpakkam


Correct Option: B
Explanation:

India conducted its first nuclear explosion at Pokharan.
Smiling Buddha (MEA designation: Pokhran-I) was the assigned code name of India's first successful nuclear bomb test on 18 May 1974. The bomb was detonated on the army base, Pokhran Test Range (PTR), in Rajasthan by the Indian Army under the supervision of several key Indian generals.

_________ is located in the Parvati valley near Manikarn in Himachal Pradesh.

  1. Tidal energy plant

  2. Solar energy plant

  3. Geothermal energy plant

  4. Atomic energy plant


Correct Option: C
Explanation:

Geothermal energy plant is located in the Parvati valley near Manikarn in Himachal Pradesh.
Geothermal power plant (flash steam, combined cycle) in Iceland. Geothermal power plants are used in order to generate electricity by the use of geothermal energy (the Earth's internal thermal energy). They essentially work the same as a coal or nuclear power plant, the main difference being the heat source.

What is meant by 'energy crisis'?

  1. Shortage of hydro-electricity

  2. Malnutrition leading to short supply of energy in the human body

  3. Shortage of the thermal power

  4. Impending danger of total exhaustion of fossil fuels like coal and petroleum


Correct Option: D
Explanation:

An energy crisis is any significant bottleneck in the supply of energy resources to an economy. In literature, it often refers to one of the energy sources used at a certain time and place, in particular those that supply national electricity grids or those used as fuel in vehicles.
