Which example is NOT a part of the electromagnetic spectrum?
Alekssandra [29.7K]

Electricity is NOT a part of electromagnetic spectrum.

An electromagnetic spectrum contains electromagnetic radiations arranged according to frequencies and wavelength.

<h2>Further Explanation </h2><h3>Electromagnetic waves  </h3>
  • Electromagnetic waves are types of waves that do not require a material medium for transmission.
  • These waves are mostly transverse in nature, which means the direction of transmission is perpendicular to the direction of vibration of particles.
  • They include, light waves, radio waves, x-rays, infra-red, etc.
<h3>Electromagnetic spectrum </h3>
  • An electromagnetic wave shows electromagnetic waves arranged according to frequencies and wavelength.  
  • Electromagnetic spectrum contains electromagnetic waves: Gamma rays, x-rays, Ultraviolet, Visible light, infra-red, microwaves, and radio waves.
  • The electromagnetic spectrum is divided into various sections based on wavelength, with gamma rays having the shortest wavelength and radio waves having the longest wavelength.
  • The part of the electromagnetic spectrum that we can see using our naked eyes is called the visible light spectrum.
  • In order of frequency, the radio waves have the lowest frequency while gamma rays have the largest frequency.
<h3>General characteristics of electromagnetic waves  </h3>
  • They travel with the speed of light (3.0 x 10^8 m/s)
  • They possess energy that is given by; E =hf, where h is the plank’s constant and f is the frequency.
  • They are transverse in nature, and therefore, the wavelength is measured between successful crests or troughs.
  • They can travel through vacuum

Keywords: Electromagnetic spectrum, electromagnetic waves.

Eating 2500 Cal every day a friend of mine maintains a stable weight of 70 kg. One day, after eating 3500 Cal, he decided to do
Kaylis [27]

Answer:

Explanation:

Calories to be burnt = 3500 - 2500 = 1000 Cals .

Efficiency of conversion to mechanical work  is 25 % .

Work needed to burn this much of Cals = 1000 x 100 / 25 = 4000 Cals.

4000 Cals = 4.2 x 4000 = 16800 J  .

Work done in one jump = kinetic energy while jumping

= 1/2 m v²

= .5 x 70 x 3.3²

= 381.15 J .

Number of jumps required = 16800 / 381.15

= 44 .

An atom has a mass of 24 and a nuclear charge of 12. Which statement about the atom is accurate?
Oksana_A [137]

The correct answer is It has equal numbers of neutrons and protons.

A characteristic that can be physically determined, the atomic mass of an atom is equal to the total mass of the protons, neutrons, and electrons that make up the atom. The number of protons in the atom's nucleus is indicated by the atomic number. It is equal to the atomic number in value. Moving over the periodic table causes the nuclear charge to grow. The charge is filled when the electrons approach the protons.

The protons and neutrons of an atom are added to determine the mass number. Therefore, the mass number for each atom will be twice the atomic number (number of protons) if the number of protons (atomic number) and neutrons are identical.
