When stars collapse and compress themselves inward to a tiny singularity they become what?
-
Nebulas
-
Black Holes
-
Asteroids
-
Comets
-
Red Giant Stars
Correct Answer
A. Black HolesExplanation
When stars collapse and compress themselves inward to a tiny singularity, they become black holes. Black holes are extremely dense regions in space where gravity is so strong that nothing, not even light, can escape its gravitational pull. The collapse of a star into a black hole occurs when the star's core runs out of nuclear fuel and can no longer support itself against gravity. The mass of the star collapses inward, forming a singularity, and the surrounding space-time is curved, creating a black hole.Rate this question:

What type of star is our Sun?
-
Yellow-Orange
-
Red Giant
-
White Dwarf
-
Blue Giant
-
Really, Really Hot
Correct Answer
A. Yellow-OrangeExplanation
Our Sun is classified as a Yellow-Orange star. This is because it emits a yellowish light, indicating its temperature and spectral type. Yellow-Orange stars have a surface temperature between 5,000 and 6,000 Kelvin, which is cooler than Blue Giants and hotter than Red Giants. The color of a star is determined by its surface temperature, with cooler stars appearing redder and hotter stars appearing bluer. Therefore, the Sun's yellowish color places it in the Yellow-Orange category.Rate this question:
