The Nebula Cloud theory is more widely accepted and supported by evidence compared to the Passing Star theory. The Nebula Cloud theory suggests that stars form within nebulas, while the Passing Star theory proposes that stars are formed by interactions with other stars.
solar system
The passing star mechanism of the origin of the solar system was proposed by British astronomer Sir James Jeans in the early 20th century. The theory suggests that our solar system was formed as a result of a close encounter between the Sun and another star billions of years ago.
what are the strengths and weakness of modernization theory
the source of the nebular cloud theory is not explained the the theory contradicts the fact related to angular momentum there wasnt enough mass in the rings to provide the gravitational pull for condensation into individual planets.
Conservation of momentum. Regularity of orbits, "Sameness" of all orbiting material. (Note - that was the preferred theory when I was young.)
weaknesses: can not controll language, actions around certain people
The passing mark in theory exams is typically around 70% or higher. However, this can vary depending on the specific exam or institution.
It is valid only for hydrogen like atoms.
No.
The twin star theory is that there may be another star similar to the star we call "the sun" that could possibly make life on another planet possible.
