Explanation

Chemical energy is stored in the bonds of chemical compounds, which is the case for fuels like coal, petroleum, natural gas, and biomass, as well as in batteries.

Multiple choice evs sources of water conservation of natural and energy resources energy conservation and sources reduce, recycle, reuse importance of the conservation of natural resources

To meet energy crisis what other sources can be exploited?

  1. Wind

  2. Water

  3. Nuclear

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

The wind, water, and nuclear energy are renewable forms of energy resources. These reserves once consumed can be replenished again. When there is an energy crisis, due to the reduction in the number of energy reserves, there will be an increase in the use of renewable resources. These energy resources can be exploited for the production of energy when there are no other resources available. 

Thus, the correct answer is option D. 

Multiple choice physics sources of energy wave energy tidal energy wave power and tidal power

  3. tidal energy

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

Renewable energy obtained from the ocean is together termed as ocean energy. Thus, ocean energy can be classified into various categories such as ocean thermal energy, tidal energy and wave energy.

Multiple choice physics sources of energy wave energy tidal energy wave power and tidal power

The energy available due to the difference in the temperature of water at the surface of the ocean and at deeper levels is called

  4. none of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The energy derived from the temperature difference between surface water and deep ocean water is known as Ocean Thermal Energy Conversion (OTEC).

Multiple choice physics sources of energy wave energy tidal energy wave power and tidal power

What are the energy from sea in the below options?

  1. Tidal energy

  2. Wave energy

  3. Ocean thermal energy

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

Tidal -Because of  gravitation pull of Moon, tides in sea are seen.Tidal energy is a form of hydropower which utilizes energy from tides to produce electricity.
Wave - Waves are good source of energy. Waves from the sea are used to run the turbines to generate electricity.
Ocean thermal energy - Water at sea surface is hot during daytime and at lower level is cold. This temperature difference is used to produce energy (electric).

Multiple choice physics sources of energy wave energy tidal energy wave power and tidal power

Wave energy harnesses :

  1. winds produced by huge waves.

  2. waves formed by tides.

  3. potential energy of normal waves.

  4. kinetic energy possessed by huge waves.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In wave energy, kinetic energy possessed by huge waves is trapped to generate electricity with the help of a machine called wave energy convertor. 

Multiple choice physics sources of energy wave energy tidal energy wave power and tidal power

Tidal energy is harnessed by:

  1. transporting sea water to a close dam.

  2. constructing a submerged dam.

  3. constructing a dam across a narrow opening to the sea.

  4. constructing an overhead dam.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Difference in sea-levels due to tides during different times of day gives us tidal energy. Tidal energy is harnessed by constructing a dam across a narrow opening to the sea. A turbine fixed at the opening of the dam converts tidal energy to electricity.

Multiple choice physics air, winds and cyclones wind and rain example of some natural phenomena uneven heating of earth

Which source of energy makes use of the air pressure in generation of energy ?

  1. Hydroelectric Power plant

  2. Nuclear reactor

  3. Windmill

  4. Thermal power plant
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Windmill makes use of the air pressure in the generation of energy, as hydroelectric power plants capture the energy of falling water to generate electricity.
A nuclear reactor produces electricity by chain reaction produces the energy, which turns water into steam. The pressure of the steam turns a generator, which produces electricity. 
In a thermal power plant fuel is burned to produce heat, this heat is used to change water into steam. this drives the generator to produce electricity.
Whereas in windmill the energy in the wind turns two or three propeller-like blades around a rotor. The rotor is connected to the main shaft, which spins a generator to create electricity.
Multiple choice biology food production food production and microorganisms microbial products - food, medicines and industrial products uses of microorganisms

Technologies break down various plant materials (for example, cellulose, lignin and xylan from crops) and it results in a

  1. Non-biodegradeable

  2. Less toxic

  3. Biomass

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

The productivity of plants as biofuel or biomaterial crops is established by both the yield of plant biomass per unit area of land and the efficiency of conversion of the biomass to biofuel. Genomics approaches support genetic selection strategies to deliver significant genetic improvement of plants as sources of biomass for biofuel manufacture. Genetic modification of plants provides a further range of options for improving the composition of biomass and for plant modifications to assist the fabrication of biofuels. The relative carbohydrate and lignin content influences the deconstruction of plant cell walls to biofuels. Key options for facilitating the deconstruction leading to higher monomeric sugar release from plants include increasing cellulose content, reducing cellulose crystallinity, and/or altering the amount or composition of noncellulosic polysaccharides or lignin. Modification of chemical linkages within and between these biomass components may improve the ease of deconstruction. Expression of enzymes in the plant may provide a cost-effective option for biochemical conversion to biofuel.

Therefore, the correct answer is option D.

Multiple choice origin of universe universe and organic evolution biology

The ultimate source of our energy is 

  1. Sun

  2. Electricity

  3. Wind

  4. Plants
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The sun is called the ultimate source of energy because it is the source of almost all energies of the earth. Plants convert light energy from the sun into chemical energy (food) by the process of photosynthesis. Animals eat plants and use that same chemical energy for all their activities.

So, the correct answer is 'Sun'.

Multiple choice biology properties of natural resources the concept of bernoulli's principle variations in atmospheric pressure air exerts pressure

Which of the following are the uses of air?

  1. Generating electricity

  2. Disposal of seeds

  3. Flying of birds

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

Air is used in generating electricity for example wind mill is used to generate electricity. 

Dispersal of seeds means transport of seeds away from parent plant. Gravity, wind, ballistic, water and by animals are five modes of seed dispersal. 
Flying of birds as bird use their strong breast muscles to flab their wings and give them the thrust to move through the air and fly.

Multiple choice physics pressure in liquids and gases pressure dependence on force and area concept of pressure pressure on surface

In a hydel station, the motion produced in turbines is due to the

  1. burning of coal

  2. burning of diesel

  3. flow of water

  4. production of steam
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Water flowing in the river is comprised of kinetic energy and potential energy. In hydroelectric power plants the potential energy of water is utilized to produce electricity.

The dam is the most important component of hydroelectric power plant. The dam is built on a large river that has abundant quantity of water throughout the year. It should be built at a location where the height of the river is sufficient to get the maximum possible potential energy from water.
