Multiple choice evs solar energy renewable and non-renewable resources renewable and non-renewable sources of energy substances, objects and energy solar power plant production of electricity from solar energy solar energy and its applications

Coal and petroleum are called fossil fuels.      

  1. True

  2. False

  3. Ambiguous

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

Answer is A.

It is because they are actually fossils. They are made of dead and decay matter buried under the earth for many years. The dead and decaying matter under great amount of pressure and temperatures turn into fossils and they both are used as fuels so it is called fossil fuels.
The fossil fuels we use today are actually formed from plants and animals that existed hundreds of millions of years ago. The reason there is a lot of concern surrounding the expenditure of these resources is because most of what we use today from fossil fuels, such as oil and coal are being depleted much faster than they can be formed, so there is a limited amount available.
Hence, the statement is true.

B Correct answer
Explanation

Solar panel refers either to a photovoltaic module, a solar hot water panel, or to a set of solar photovoltaic (PV) modules electrically connected and mounted on a supporting structure. A PV module is a packaged, connected assembly of solar cells. Solar panels can be used as a component of a larger photovoltaic system to generate and supply electricity in commercial and residential applications.

Water cannot be heated using a solar water heater on a.

  1. windy day

  2. sunny day

  3. cloudy day

  4. hot day
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Solar water heater works on solar radiation falling on it. It requires solar light for generating enough heat to heat water. During cloudy days, Sun is obstructed by clouds, and the light incident of the solar panels will be inefficient to make the heater work.
