Solar system coalesced out of a swirling cloud of interstellar dust/gas is known as nebula gas theory
According to nebula gas theory, the Sun and all the planets of our Solar System began as a giant cloud of molecular gas and dust called solar nebula. Then, about 4.57 billion years ago, something happened that caused the cloud to collapse.
A shock wave from a nearby supernova explosion probably initiated the collapse of the solar nebula. The Sun formed in the center, and the planets formed in a thin disk orbiting around it.
Nebular Hypothesis: a widely accepted model. Originally formulated in 1755 by a German Philosopher Immanuel Kan. Its subsequent development has interwoven a variety of scientific disciplines including astronomy, physics, geology, and planetary science. The solar system coalesced out of a swirling cloud of interstellar dust/gas called nebula. Sun born from a nuclear reaction called nebula.

A plasma is an ionized gas , a gas into which sufficient energy is provided to free electrons from atoms or molecules and to allow both species , ions and electrons to coexist , Gases can become plasma in several ways , but all include pumping the gas with energy,
<h2>
Answer: Marie Curie's notebooks</h2>
Explanation:
Marie Curie's notebooks, as well as all of her belongings, including her clothes, were contaminated with ionizing radiation. In fact, also those of her husband, because <u>this couple of scientists discovered the radioactivity of several elements</u>, helping the advance of science, but did not know about the consequences of dealing with these materials without adequate protection.
It should be noted that Curie's notes are stored in the basements of the National Library of France, stored in thick lead boxes and those who wish to access these documents must follow the appropriate protocol to treat radioactive material, wear appropriate clothing and sign a responsibility agreement before allowing them to review the documents.
Answer:
6666.67 Newtons
Explanation:
The formula F=ma (force is equal to mass multiplied by acceleration) can be used to calculate the answer to this question.
In this case:
- mass= 0.1mg= 1*10^-7 kg
- velocity= 4.00*10^3 m/s
- time= 6.00*10^-8 s
Using velocity and time, acceleration can be calculated as:
Substituting these values into the formula F=ma, the answer is:
- F= (1*10^-7)kg * (6.667*10^10) m/s²
- F= 6666.67 Newtons of force
