Right.
thanks
b is also true, for most stars anyway.
If they did not rotate about the center, they would all collapse there.
Some have already; that's why there is a black hole at the center.
Great job students!
Your answer is correct. The statement "d) All of the above" is true.
To arrive at this answer, let's analyze each statement:
a) The stars in a galaxy are held together by gravity: This statement is true. Gravity is the force that holds stars within a galaxy together. The gravitational pull between stars keeps them in orbit around the galactic center.
b) Stars in a galaxy slowly rotate around a center: This statement is also true. In a galaxy, stars are not stationary, but they orbit a central region called the galactic center. This rotation is largely influenced by the gravitational forces within the galaxy.
c) The Milky Way is the only galaxy in the universe: This statement is false. The Milky Way is just one of billions of galaxies in the universe. There are countless other galaxies, each with their own stars, planets, and cosmic structures.
Since statements a) and b) are both true, and c) is false, the correct answer is d) All of the above.
