Answer:
Explanation
Be active on social media. Now I don't mean to be addicted to it, like alot of people are. Instead, just put yourself out there. Be friendly and social, and remember think before you post. This is because your things you post and do online are permantely stored, even if you delete it. Many job employers and schools look and do a quick look up of you online, just to check your background and see if you are fit. Also to keep a positive digital footprint, try to delete and deactivate accounts online, ex. social platform, blogs, because then it won't be searchable online.
Took the test just now, Answer is D.
Answer:
The photosphere, the chromosphere and the ionosphere.
Explanation:
You did not list any layers in your question, however, the sun is composed of mainly 6 layers;
- The core
- The radiative zone
- The convective zone
- The photosphere
- The chromosphere
- The corona
The photosphere is the visible layer of the sun, however, it is very bright even when viewed with a telescope. A filter has to be used to reduce the intensity of the light. This filter is called a myler filter. It is added to the lens of the telescope. Using this, the photosphere can be seen using a telescope.
The chromosphere is an irregular layer above the photosphere. Due to the extremly high temperature, hydrogen emits light which gives off a reddish color. This is known as the H-alpha emmision. Therefore, to see this layer with a telescope, a special filter have to be fitted to the lens of the telescope. This filter is called the hydrogen alpha filter.
The corona is the outermost part of the sun atmosphere, however, it is hidden by the sun's bright surface. It can be seen during a total eclipse. This is when the moon covers the bright photosphere.
