Why do electrons do not fall in nucleus?
Why do electrons do not fall in nucleus? Quantum mechanics states that among all the possible energy levels an electron can sit in the presence of a nucleus, there is one, which has THE MINIMAL energy. This energy level is called the ground state. So, even if atoms are in a very very called environment, […]
What is photosynthesis answer in one line?
What is photosynthesis answer in one line? Photosynthesis is the process by which plants and some microorganisms make substances like carbohydrates. It is an endothermic (takes in heat) chemical process that uses sunlight to turn carbon dioxide into sugars. The sugars are used by the cell as energy, and to build other kinds of molecules. […]

What are the factors affecting the height of the waves?
What are the factors affecting the height of the waves? Wave height is affected by wind speed, wind duration (or how long the wind blows), and fetch, which is the distance over water that the wind blows in a single direction. If wind speed is slow, only small waves result, regardless of wind duration or […]
