(a) Neil A. Armstrong was the first person to walk on the moon. The distance between the earth and the moon is 3.85 x 108 m. Find the time it took for his voice to reach the earth via radio waves. (b) Someday a person will walk on Mars, which is 5.60 x 1010 m from the earth at the point of closest approach. Determine the minimum time that will be required for a message from Mars to reach the earth via radio waves.

Question
![**Problem Description:**
(a) Neil A. Armstrong was the first person to walk on the moon. The distance between the earth and the moon is \(3.85 \times 10^8\) m. Find the time it took for his voice to reach the earth via radio waves.
(b) Someday a person will walk on Mars, which is \(5.60 \times 10^{10}\) m from the earth at the point of closest approach. Determine the minimum time that will be required for a message from Mars to reach the earth via radio waves.
**Input Fields:**
- (a) Number: [______] Units: [______]
- (b) Number: [______] Units: [______]
**Explanation:**
To solve these problems, use the formula:
\[ \text{Time} = \frac{\text{Distance}}{\text{Speed of Light}} \]
The speed of light (radio waves) is approximately \(3.00 \times 10^8\) meters per second (m/s).
Calculate the time for each scenario by dividing the distance by the speed of light and input the results in the fields provided, selecting the appropriate units.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F56ce7dbd-1bb3-46f5-bd75-66c1a6a5b2a1%2F2c9b9f86-a3ca-4a04-bd8d-4a602126d36a%2Fizvqy1_processed.jpeg&w=3840&q=75)
