Energy Resources and Storage Questions

Multiple choice

Which of the following cannot be considered as an energy source?

  1. Generator

  2. Transformer

  3. Solar cell

  4. Rheostat

  5. Battery
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Rheostat is the variable resistance, i.e. we can vary the value of resistor using rheostat. Rheostat is not energy source. It is used only to increase or decrease the given voltage value in lab experiments. Option 4 is correct.

Multiple choice

Which source of electric energy is non-renewable?

  1. solar panels

  2. windmills

  3. dams

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

Coal is a fossil fuel that takes millions of years to form and cannot be replenished on a human timescale, making it a non-renewable energy source.

Multiple choice

Which of the following is an example of a renewable resource?

  1. Natural gas

  2. Petroleum

  3. Coal

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

Wind is a renewable resource because it is naturally replenished by atmospheric processes. Natural gas, petroleum, and coal are fossil fuels that take millions of years to form and are non-renewable.

Multiple choice

Which of the following is NOT identified as a renewable resource?

  1. Fish population

  2. Natural vegetation

  3. Coal deposits

  4. Corn crops
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Coal is a fossil fuel formed over millions of years and cannot be replenished on a human timescale, making it a non-renewable resource. Fish, vegetation, and crops can reproduce and replenish themselves.

Multiple choice

Energy derived from the sun is called

  1. hydroelectric energy

  2. geothermal energy

  3. solar energy

  4. biofuel energy
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Energy that comes from the sun is known as solar energy. Hydroelectric energy comes from water, and geothermal energy comes from the Earth's internal heat.

Multiple choice

An option used for powering cars as an alternative to fossil fuels is...

  1. geothermal energy

  2. hydroelectric energy

  3. gasoline

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

Biofuel is a renewable energy source derived from organic matter (like plants) that can be used as a substitute for gasoline in vehicles. Geothermal and hydroelectric energy are not typically used to power individual cars.

Multiple choice

Which is an example of a nonrenewable resource

  1. geothermal energy

  2. natural gas

  3. sunlight

  4. wind energy
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Nonrenewable resources exist in finite amounts and cannot be replaced on a human timescale. Natural gas is a fossil fuel that takes millions of years to form, unlike sunlight, wind, or geothermal energy which are renewable.

Multiple choice

Which of these is a fossil fuel?

  1. Geothermal

  2. Wind

  3. The Sun

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

Fossil fuels are formed from the remains of ancient organisms. Natural gas (often referred to as 'gas') is a fossil fuel, whereas wind, solar, and geothermal are renewable energy sources.

Multiple choice evs how to save fuel lpg, cng treasures from the earth fuel and conservation

The most common sources of energy are:

  1. wood and coal

  2. petroleum and coal

  3. LPG and cow dung

  4. natural gas and wood
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Fossil energy like coal, lignite, petroleum and natural gas are most common sources of energy. These sources of energy are used to produce electricity, cook food, heat thermal engines etc. 

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

From below which is the type of energy from sea?

  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

Energy from the sea can be classified into three types:

1. Tidal energy - This energy is harnessed by building a dam and placing a turbine near the opening of the dam. By using the turbine, tidal energy of the sea is used to produce electricity.
2. Wave energy - Kinetic energy of the wave is used in generation of electricity.
3. Ocean thermal energy - Thermal difference between the cold ocean water and warm tropical surface water is used to generate electricity.
