Question

how did galileo increase public support for copernicuss model? by publishing his work in italian by using data collected by tycho brahe by explaining why planets appear to move backward by arguing that earths rotation makes objects appear to move in the sky

Explanation:

Galileo published his works in Italian, the common - language of the people, making his support for Copernicus's heliocentric model accessible to a wider audience, thus increasing public support. Using Tycho Brahe's data was more about scientific research rather than directly increasing public support. Explaining retrograde motion and Earth's rotation were scientific explanations mainly for the scientific community rather than a key factor in increasing public support.

Answer:

by publishing his work in Italian
