5: Flux is not related to the distance from the source. - False
4: A G star is hotter than an M star.. - True
3: Parallax is a good method to find the distance to a star say 1300 LY away. - True
Parallax is the effect in which the position of an object is different when viewed from different positions like through the viewfinder and the lens of a camera.
5. Flux is the amount of rays or lines passing through a particular closed area. So, Flux is not related to the distance from the source.
Thus, the statement is false.
4. A G star is a yellow star mainly characterized by a surface temperature of around 5,500 kelvins.
An M star is a red star characterized by a surface temperature of 3,000 kelvins or less.
So, a G star is hotter than an M star.
Thus, the statement is true.
3. Parallax is a good method to find the distance to a star say 1300 LY away. Parallax gives us respective distances of the star or planet whose distance need to find.
Thus, the statement is true.
