Question 20 Consider the statement: "Earth moves in a stable orbit around the Sun and is therefore in equilibrium". The statement is: O A. false, because the Earth is rotating on its axis and no rotating body can be in equilibrium O B. false, because no moving body can be in equilibrium O C. true, because the Earth does not fall into or fly away from the sun O D. false, because the Earth has a considerable acceleration O E. true, because if it were not in equilibrium then buildings and structures would not be stable
