Answer:
hydrogen nuclei fuse forming helium and releasing energy.
Explanation:
The Sun's light is generated by a nuclear reaction. In this reaction, hydrogen nuclei fuse forming helium and releasing energy. This reaction releases so much energy that light is able to travel all the way from the Sun to the Earth. On the Earth, this light energy is transformed into chemical potential energy during photosynthesis.

In Dalia Kirschbaum work, she uses weather data collected by NASA satellites to study landslides events.
landslides
<u>Explanation:</u>
Dalia Kirschbaum is an examination researcher who the two investigations avalanches and assists with organizing the calamity reaction when one happens. She utilizes climate information gathered by NASA satellites to contemplate avalanches occasions.
She is the GPM Applications Scientist, implying that she conveys the science and the information that she get from the GPM crucial people in general and end-clients. Dalia Kirschbaum experienced childhood in Minnesota, and she chose to seek after a zone where there truly was an absence of research.
Understanding avalanches with regards to remote detecting is quite new. We are as yet making sense of how to move toward displaying avalanche action and applying the remote detecting information NASA and different organizations gather at a bigger spatial scale.
Perfect competition is the simplest market structure, where the market is assumed to be in equilibrium and that all sellers sell the same product at the same price. The four conditions for perfect competition are:
1. There are many buyers and sellers in the market so that no one individual or seller can influence the price of the products, goods, and services.
2. Identical products are offered by the sellers
3. Both the buyers and the sellers are well-informed about the products and want to maximize profit.
4. Entry and exit to and from the market can be done freely by the sellers and buyers.
There is no market which displays 100% perfect competition. However, markets exhibiting nearly perfect competition do exist. These include street food vending and agricultural markets.
