TEA [102]2 years ago

Light is a form of EM radiation.
EM radiation has no mass (it's just energy packets called photons).
EM radiation can travel through a vacuum. (The speed of light in a vacuum is called c and is around 300,000 m/s).

Hope this helps!

Answer:

  • Light is a kind of electromagnetic radiation.
  • Electromagnetic radiation has no mass.
  • Electromagnetic radiation can travel through a vacuum.

Explanation:

Electromagnetic radiation spreads in space. It has a magnetic field and an electric field that generate each other and propagate perpendicularly to each other and in the direction of propagation of energy, thus transporting energy in the form of electromagnetic radiation. Electromagnetic radiation varies with the frequency of the wave. The light visible to human eyes is electromagnetic radiation, just like x-rays, the only difference between these two forms of radiation is in the frequency range that the human eye can see, that is, x-rays have a frequency range that is out of reach of human vision. The waves in the microwave oven are also electromagnetic waves.

In summary, we can say that:

  • Light is a kind of electromagnetic radiation.
  • Electromagnetic radiation has no mass.
  • Electromagnetic radiation can travel through a vacuum.

What process occurs in Box A?
SIZIF [17.4K]

Answer:

The process occurring in Box A is Glycolysis

Explanation:

Glycolysis is the pathway by which glucose, a six-carbon molecule is oxidized to molecules of pyruvate, a three-carbon molecule with the release of ATP and electrons which are carried by NADH molecules.

The process occurs in the cytoplasm of cells and requires 10 glycolytic enzymes.

The pyruvate molecules from glycolysis is first oxidized to acetyl-CoA and carbon dioxide molecules. The acetyl-CoA molecules enter the citric acid cycle occurring in the mitochondria and are used up in the production of  ATP, CO2, and electrons carried by NADH and FADH2.

The electrons carried by NADH and FADH2 from glycolysis and citric acid cycle are used in the oxidative phosphorylation pathway occurring inside the mitochondrion for transformation of oxygen molecules into water molecules with release of ATP.

The land on the leeward side of a mountain range is in a rain shadow.<br> (True or False question)
Dmitry [639]
<span>The Leeward side of a mountain range is in fact in a rain shadow. A rain shadow is an area of elevation where little to no rain falls, due to precipitation being forced out of passing clouds on the windward side of the mountain. Precipitation condenses as clouds rise over the mountain, and in general it precipitates as it crests over the mountain, leaving no moisture for the leeward side. An example of this is the American west, just west of the Rockies, where little to no rain falls.</span>
