Multiple choice physics energy production

Green house effect is the:

  1. trapping of radiation in the atmosphere

  2. trapping of water molecule in the atmosphere

  3. trapping of gases in the atmosphere

  4. none of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Our atmosphere allows the high frequency radiation (Infrared rays) to pass through it, which comes from sun. This radiation reaches to earth and after some absorption (this radiation is also absorbed and radiated by green house gases), earth reflects back low frequency radiation (Infrared rays) which cannot pass through the atmosphere. This radiation is trapped in our atmosphere and keeps our atmosphere warm, this is called green house effect.

C Correct answer
Explanation

Process of warming of planet's surface and its lower atmosphere by the absorption of infrared radiations of long wavelength given out from the surface of a planet is known as green house effect.  In 1824, Joseph Fourier discovered the green house effect.

Multiple choice physics energy production

Which of the following is not a greenhouse gas?

  1. Carbon dioxide

  2. Sulphur dioxide

  3. Methane

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

Carbon dioxide, methane, and ozone are well-known greenhouse gases. Sulphur dioxide is primarily an air pollutant that causes acid rain, not a primary greenhouse gas.

Ozone layer blocks the radiations of wave length

  1. less than $3 \times 10^{-7}$ m
  2. equal to $3 \times 10^{-7}$ m
  3. more than $3 \times 10^{-7}$ m

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

The ozone layer absorbs harmful ultraviolet radiation, specifically UV-C and some UV-B, which have wavelengths shorter than approximately 300 nm (3 * 10^-7 m).

Multiple choice physics energy production

Carbon monoxide present in the air is the cause of acid rain.

  1. True

  2. False

  3. Ambiguous

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

false,
pollution from burning of fossil fuels is the major cause of acid rain. The main chemicals in air pollution that create acid rain are sulfur dioxide ($s{o} _{2}$) and nitrogen ($N{o} _{x}$).

Multiple choice physics nuclear physics hazards and safety measures of radiations harmful effects and safety precautions for radiations energy production

Carbon dating is

  1. a process to determine the age of archaeological samples

  2. a medicine for treatment of cancer

  3. a process to determine the age of a meteorite

  4. a process of treatment of diseases in animals
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Carbon dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon (${}^{14}C$), a radioactive isotope of carbon.
