Question

how do we know the age of the sun? (select all that apply.) our models of the formation of the solar system tell us that the sun formed at the same time as the planets. studying the cosmic microwave background can give us the age of the universe. radioactive dating of rocks can give us the age of the earth and moon. measuring emissions from the x - ray source at the milky ways center can give us the age of the galaxy. our models of the formation of the solar system tell us that the sun formed several billion years before the planets.

Explanation:

Our models of solar - system formation suggest the Sun and planets formed at the same time. Radioactive dating of rocks gives the age of Earth and Moon. Since the Sun and planets formed around the same time, this can help in estimating the Sun's age. Studying the cosmic microwave background gives the age of the Universe, which provides a time - frame context for the Sun's age.

Answer:

Our models of the formation of the solar system tell us that the Sun formed at the same time as the planets.
Studying the cosmic microwave background can give us the age of the Universe.
Radioactive dating of rocks can give us the age of the Earth and Moon.
