<h3><u>Answer;</u></h3>

Diffract

Sound waves generated in a classroom must <em><u>diffract</u></em> through an open doorway in order to propagate into the hallway.

<h3><u>Explanation;</u></h3>
  • <em><u>Sound waves are a type of mechanical waves that requires a material medium for transmission,</u></em> they are longitudinal wave with all the properties of other waves.
  • <em><u>Diffraction is one of the property of waves that involves a change in direction of waves as they pass through an opening or around a barrier in their path. </u></em><u><em>Sound wave diffract around corners or through the door openings, allowing people to hear others speaking to us from rooms that are adjacent. </em></u>

How can you make the potential energy as high as possible in a magnetic field between one electromagnet and one piece of iron?
harkovskaia [24]

In step 1, to increase the potential energy, the iron will move towards the electromagnet.

In step 2, to increase the potential energy, the iron will move towards the electromagnet.

<h3>Potential energy of a system of magnetic dipole</h3>

The potential energy of a system of dipole depends on the orientation of the dipole in the magnetic field.

U = \mu B

where;

  • \mu is the dipole moment
  • B is the magnetic field

B = \frac{\mu_0 I}{2\pi r}

U = \mu\times  (\frac{\mu_0 I}{2\pi r} )

Increase in the distance (r) reduces the potential energy. Thus, we can conclude the following;

  • In step 1, to increase the potential energy, the iron will move towards the electromagnet.
  • In step 2, when the iron is rotated 180, it will still maintain the original position, to increase the potential energy, the iron will move towards the electromagnet.

According to the diagram of the electromagnetic spectrum shown, what would best represent the
iren2701 [21]

The  best represent the size of visible light will be C. Protozoa

The electromagnetic spectrum, gives the overall distribution of electromagnetic radiation by the  frequency or wavelength. All EM waves travel at the speed of light in a vacuum, but over a wide range of frequencies, wavelengths, and photon energies.

Visible light wavelengths cover the range of approximately 0.4 to 0.7 μm. electromagnetic spectrum that the human eye can see is the Visible light. Visible light is a form of electromagnetic (EM) radiation, along with radio waves, infrared, ultraviolet, X-rays, and microwaves. the wavelengths that are visible to most human eyes is generally known as Visible light

the best represent the size of visible light is Protozoa, According to the diagram of the electromagnetic spectrum shown,
