Question

question 23 (multiple - choice, worth 2 points) oss.01which of these statements is most likely correct about the nebular theory of formation of planetary systems? it predicts facts and evidences for non - observable scientific research. it describes events in nature which are non - observable and non - testable. it is a universal theory which cannot be challenged by new experimentations. it is a valid explanation because it is based on the investigation of current evidences. question 24 (multiple - choice, worth 2 points) oss.01the laws surrounding the motion of planets in our solar system can be replaced by new laws. describe what happens in nature under certain conditions. prove that theories on space are non - testable. can be used to prove that theories on gravity are non - observable. question 25 (multiple - choice, worth 2 points) oss.03scientists have observed a sudden explosion in the sun followed by rapid changes in the suns brightness. which of these events would most likely occur due to this solar condition? change in wind velocity. change in earths climatic pattern. increase in number of solar eclipses. increase in atmospheric pollution on earth.

Explanation:

Question 23

The nebular theory is based on evidence from current research. Scientific theories are valid when supported by evidence. It's not about non - observable or non - testable events, nor is it unchallengeable.

Laws in science describe natural phenomena under certain conditions. They are not about proving non - testability of space theories or non - observability of gravity theories, and they are not easily replaced.

Sudden solar explosions can release a large amount of energy and radiation that can affect Earth's climate. Wind velocity is not directly related, solar eclipses are not affected by solar brightness changes, and it doesn't directly cause atmospheric pollution.

Answer:

It is a valid explanation because it is based on the investigation of current evidences.
