Question

1. what distance separates earth and the sun? a. 300,000 kilometers per second b. eight light minutes c. 149 million light seconds d. one light - year

Explanation:

• Option A: 300,000 kilometers per second is the speed of light, not a distance between Earth and the Sun.
• Option B: Light travels at about 300,000 km/s, and the distance from Earth to the Sun takes light about 8 minutes to cover, so "eight light - minutes" is a correct way to express this distance.
• Option C: 149 million kilometers is the average distance (astronomical unit), and a light - second is about 300,000 km. 149 million km is about 497 light - seconds, not 149 million light - seconds.
• Option D: A light - year is the distance light travels in a year, which is much larger than the distance from Earth to the Sun (the Sun is about 0.0000158 light - years from Earth).

Answer:

B. Eight light minutes
