4 0

Answer:

.

Explanation:

sunspots are areas that appear dark on the sun's surface.They appear dark because they are colder that parts of the sun's surface. However, the temperature of a sunspot is still very high. This can cause a sudden burst of energy space. If a solar flare is very intense, the radiation it releases can interfere with our radio communication here on earth

How are weathering, erosion, and deposition related to the rock cycle
xenn [34]

Answer:

Erosion is the process by which natural forces move weathered rock and soil from one place to another. Gravity, running water, glaciers, waves, and wind all cause erosion. The material moved by erosion is sediment. Deposition occurs when the agents (wind or water) of erosion lay down sediment.

astra-53 [7]

Answer:

Substances that enhance the flow of current are called conductors

Substances that inhibit the flow of current are known as insulators

Substances that neither conduct nor inhibit are called semiconductors

Explanation:

  • Substances that enhance the flow of current are called conductors because they allow electrical charges to pass through them.
  • Substances that inhibit the flow of current are known as insulators because they prevent the flow of electrical charges through them.
  • Substances that neither conduct nor inhibit  flow of current as well are called semiconductors. These substances although they cannot conduct of prevent the flow of current, in certain conditions they can be made to conduct and reversed as well.

valina [46]

If you speed through a construction zone while workers are present, your fines could be as much as one thousand dollars.

<h3>What is a Fine?</h3>

This is referred to as the amount which is instructed by a court or authority to be paid as a result of it being a penalty for various types of offences. each crime has its specific fine which helps to serve as deterrent for unlawful behavior in the community.

it is always best not to speed when within a construction zone which has workers present in the area. This is ideal as it helps to prevent incidences of accidents or death.

it is therefore the reason why a fine of 1000 dollars is to be paid so that people can think of such high amount before performing certain types of activities when driving and makes it the most appropriate choice.

How is the polarization of an electromagnetic wave defined? Group of answer choices The polarization is defined by the plane in
Anarel [89]

Answer:

The polarization is defined by the plane in which the electric field is oscillating.

Explanation:

The polarization of an electromagnetic wave depends on the direction of the electric field. If the electric component is oscillating along the x-axis, the polarization will also be along the x-axis.

The polarization of the electromagnetic wave describes the magnitude and the direction of the electric field of the wave.

<u>The polarization is defined by the plane in which the electric field is oscillating.</u>
