Question

1. what is the sun composed of? which state of matter do these materials exist? 4. what is the role of the sun in the solar system? how does it hold the planets in their orbits? 5. how are the planets protected from the suns magnetic field? how does the suns magnetic field become

Explanation:

1. The sun is mainly composed of hydrogen and helium. These materials exist in a plasma state, which is a high - energy state where atoms are ionized.
2. The sun is the central star of the solar system. Its large mass creates a gravitational force that holds the planets in their orbits according to Newton's law of universal gravitation.
3. Some planets like Earth are protected from the sun's magnetic field by their own magnetic fields. The sun's magnetic field is generated by the movement of charged particles (plasma) in its convective zone through the dynamo effect.

Answer:

1. The sun is mainly composed of hydrogen and helium, existing in a plasma state.
2. The sun is the central star, and its gravity holds planets in orbit.
3. Some planets are protected by their own magnetic fields, and the sun's magnetic field is generated by plasma movement via the dynamo effect.
