This is the quiz that deals with the Black holes, Nebulas, and beyond.
- 1.
What are the names of the smaller types of Black Holes we saw in our video?
- A.
Stellar Mass Black Holes
- B.
Big Black Hole
- C.
Super Massive Black Hole
- D.
Super Duper Black Hole
Correct Answer
A. Stellar Mass Black HolesExplanation
The correct answer is "Stellar Mass Black Holes." In the video, the names of the smaller types of Black Holes mentioned were not "Big Black Hole," "Super Massive Black Hole," or "Super Duper Black Hole." Instead, the video specifically referred to "Stellar Mass Black Holes" as the smaller types of Black Holes.Rate this question:

What is the name of the larger type of Black Hole we was in our video?
- A.
Stellar Mass Black Holes
- B.
Super Massive Black Holes
- C.
Giant Black Holes
- D.
Super, Super, Super Duper Black Holes
Correct Answer
B. Super Massive Black HolesExplanation
The correct answer is "Super Massive Black Holes." In the video, they mentioned a larger type of black hole, and this term accurately describes these enormous black holes that can be millions or billions of times more massive than our sun. They are typically found at the centers of galaxies and have a gravitational pull that affects the motion of stars and gas around them.Rate this question:

Nebulas are composed mostly of what?
- A.
Comets
- B.
Black Holes
- C.
Clouds of gas and dust
- D.
Asteroids
Correct Answer
C. Clouds of gas and dustExplanation
Nebulas are composed mostly of clouds of gas and dust. Nebulas are vast regions of space where stars are born. These clouds consist of various elements such as hydrogen, helium, and other heavier elements. The gas and dust within nebulae can come together under the force of gravity to form new stars and planetary systems. Therefore, the correct answer is clouds of gas and dust.Rate this question:

When stars collapse and compress themselves inward to a tiny singularity they become what?
- A.
Nebulas
- B.
Black Holes
- C.
Asteroids
- D.
Comets
- E.
Red Giant Stars
Correct Answer
B. 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?
- A.
Yellow-Orange
- B.
Red Giant
- C.
White Dwarf
- D.
Blue Giant
- E.
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:
