Ascientist observes two stars in the night sky through a telescope. star a is white in color and relatively dim. the star’s estimated temperature is very high.
star b is red in color and extremely bright. the star’s temperature is low compared with other stars.
the scientist classify the two stars.
star a is ( a. black dwarf b. white dwarf c. neutron star d. red supergiant)
and star b is ( a. black hole b. red dwarf c. red giant d. supernova)

Star A is a neutron star and star B is a red giant.

Explanation:

Out of the given for star A, a Neutron star is a very hot star, very small in size and hence dim and is white in color. A neutron star results after a massive star goes supernova. It is primarily composed of neutrons packed in a small boundary.

Out of the given options star B would be a red giant. This is because, a red giant star is red in color, is very big in size and has a low temperature. A red giant star is a towards the end stage of a small to an average mass star.

probably not if net force is zero

i think it's 35 meters
