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.

Explanation :

The electromagnetic spectrum shows the wavelength or frequency range of any wave.

It consists of the following waves :

  • Gamma rays (short wavelength or high frequency)
  • X-rays
  • Ultraviolet rays
  • Visible light
  • Infrared rays
  • Microwaves
  • Radio waves (long wavelength or short frequency)

So, the purple light is not the part of the electromagnetic spectrum.

Hence, the correct option is (c).

Which of the following is an expression of Newton's second law? O A. The acceleration of an object is determined by its mass and
dangina [55]

Answer: is A

The acceleration of an object is determined by its mass and the net force acting on it.

Newton's second law says that "F=ma". what this means is that the force you apply to an object is equal to its mass times how fast it is accelerating.

Hope it helped.

A thin, light wire 75.2 cm long having a circular cross section 0.560 mm in diameter has a 25.2 kg weight attached to it, causin
blsea [12.9K]

Answer:

The stress is calculated as 1.003\times 10^{9}\ Pa

Solution:

As per the question:

Length of the wire, l = 75.2 cm = 0.752 m

Diameter of the circular cross-section, d = 0.560 mm = 0.560\times 10^{- 3}\ m

Mass of the weight attached, m = 25.2 kg

Elongation in the wire, \Delta l = 1.10\ mm = 1.10\times 10^{- 3}\ m

Now,

The stress in the wire is given by:

Stress,\ \sigma = \frac{Force,\ F}{Area,\ A}          (1)

Now,

Force is due to the weight of the attached weight:

F = mg = 25.2\times 9.8 = 246.96\ N

Cross  sectional Area, A = \pi (\frac{d}{2})^{2} = \pi (\frac{0.560\times 10^{- 3}}{2})^{2} = 2.46\times 10^{- 7}\ m^{2}

Using these values in eqn (1):

\sigma = \frac{246.96}{2.46\times 10^{- 7}} = 1.003\times 10^{9}\ Pa

DENIUS [597]

Answer:

See the explanation below

Explanation:

We must perform a sum of forces on the body, that sum of forces is equal to zero. That is, the body is in balance and does not move.

ΣF = 0

3 - 3 = 0

This force is negative and acts by pointing downwards.
