multiple-choice question
how long does it take for light to travel from the sun to earth?
8 seconds
19,000 years
4 years
8 minutes

Explanation:

The speed of light is about 299,792 kilometers per second. The average distance from the Sun to Earth (the astronomical unit) is about 149.6 million kilometers. Using the formula \( time = \frac{distance}{speed} \), we calculate the time light takes to travel from the Sun to Earth. \( \frac{149600000\ km}{299792\ km/s} \approx 499\ seconds \), which is approximately 8 minutes. The other options (8 seconds is too short, 10,000 years and 4 years are way too long for light's travel time between Sun and Earth) are incorrect.

Answer:

D. 8 minutes (assuming the last option is labeled D; if the options are labeled differently, adjust the label but the text is "8 minutes")
