Question:

Select the correct answer. Which of the following notes would be most relevant if you were researching the effects of solar flares? -
ОА.
B.
Radio waves and gamma rays are types of radiation.
Communication systems can be disrupted.
The solar Hares occur often at the height of the cycle.
Ос. .
When built-up energy is released from the Sun, causes a bright spot to suddenly
appear on the Sun's surface. These bright spots are what scientists cal a solar fare
When energy is released in this manner, high-energy particles are also heated and
discharged into the Sun's outermost atmosphere
The first time a solar flare was observed was on September 1, 1859. Scientists
Richard Carrington and Richard Hodgson had been both looking at sunspots on their
own. They noticed some of the sunspots brightened. After this discovery, scientists
observed that the solar flares occurred in roughly an 11-year period. When the Sun's
cycle reached its height, the number of detected solar fares increased.
Even though solar flares stay near the Sun, they impact the space around the Sun. A
solar flare can release radiation that can come in such forms as radio waves and
gamma rays. A solar flare poses a threat to astronauts out in space because it can
expose them to high levels of radiation. It can also damage space equipment. On Earth,
radiation can disrupt the radio communication from satelites. The extra currents of
energy that reach Earth can overheat power lines. This, in turn, will affect power grids
around the world
OD.
Solar flares occur almost every 11 years.

Answers are in document attached.

For the first question

Answers:

b.) All these technologies use radio waves, including high-frequency microwaves

d.) Microwave ovens emit in the same frequency band as some wireless Internet devices.

e.) The radiation emitted by wireless Internet devices has the shortest wavelength of all the technologies listed above.

f.) All these technologies emit waves with a wavelength in the range of 0.10 to 10.0 m.

For second question

B. The earth absorbs visible light and emits radiation with a longer wavelength

C. The earth absorbs visible light and emits radiation with a lower frequency.

Both options are correct

Explanation:

In the EM spectrum, wavelenght reduces with increasing energy and frequency increases with increasing energy. The order of increasing energy is radio wave, microwave, infrared rays, visible rays, ultraviolet rays, xrays, gamma rays.

If the earth absorbs visible rays of higher energy, and radiates infrared rays of lower energy, then this means that the radiated radiation will have a longer wavenght, and a lower frequency.

the answer is d The solar flares occur often at the height of the cycle

Explanation:

i took the test

P waves are faster S wave are slower P waves can pass through both solids and liquids S waves bounce of solids

  plan: i will begin with a quotation about the importance of unity in a community. then, i will state my claim that an activity will unite our school by creating a shared vision, purpose, and direction. in the body, i will use three main points that describe the different avenues the students can take: through a variety of clubs, through a special event, or through an awareness week. i will provide evidence about other towns that have unity activities and the kinds of events that they include. pictures will illustrate my three main points in action. for the ending, i will restate the main idea in a new way and pose a question to keep the audience thinking.
