hey guys good evening all
I have a question define
1. sun
2. solar system
3. stars
4. space
5. black hole
Answers
Answer:
1.The Sun is the star at the center of the Solar System. It is a nearly perfect sphere of hot plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy mainly as visible light and infrared radiation. It is by far the most important source of energy for life on Earth.
2.The Solar System is the gravitationally bound system of the Sun and the objects that orbit it, either directly or indirectly. Of the objects that orbit the Sun directly, the largest are the eight planets, with the remainder being smaller objects, the dwarf planets and small Solar System bodies.
3.A star is an astronomical object consisting of a luminous spheroid of plasma held together by its own gravity
4.Space is the boundless three-dimensional extent in which objects and events have relative position and direction.
5.A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
Explanation:
1. sun - The Sun is a star which is located at the center of our solar system. It is a yellow dwarf star. It gives off energy as light.
2. solar system - The Solar System is the gravitationally bound system of the Sun and the objects that orbit it, either directly or indirectly.
3. stars - A star is a luminous ball of gas, mostly hydrogen and helium, held together by its own gravity
4. space - space is a vacuum, meaning that sound cannot carry because molecules are not close enough together to transmit sound between them.
5. black hole - A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it.
