How much time is required for reflected sunlight to travel from the Moon to Earth if the distance between Earth and the Moon is 3.85 x 10 to the 5th exponent?
t=distance/speed of light.
speed of light c=3•10⁸ m/s
1.28
To find the time required for reflected sunlight to travel from the Moon to Earth, we can use the speed of light, which is approximately 3 x 10^8 meters per second.
The distance between Earth and the Moon is 3.85 x 10^5 kilometers. To convert this distance to meters, we need to multiply by 1000 (since there are 1000 meters in a kilometer).
3.85 x 10^5 kilometers = 3.85 x 10^5 kilometers x 1000 meters/kilometer
= 3.85 x 10^8 meters
Now, we can use the distance and the speed of light to calculate the time it takes for reflected sunlight to travel from the Moon to Earth.
Time = Distance / Speed
= (3.85 x 10^8 meters) / (3 x 10^8 meters/second)
= (3.85 x 10^8) / (3 x 10^8)
= 1.28 seconds
Therefore, it takes approximately 1.28 seconds for reflected sunlight to travel from the Moon to Earth.
To calculate the time required for reflected sunlight to travel from the Moon to Earth, we can use the speed of light, which is approximately 299,792 kilometers per second (kps).
First, let's convert the distance between Earth and the Moon, which is 3.85 x 10^5 kilometers, into meters. To do that, we multiply the distance by 1000 since there are 1000 meters in a kilometer:
3.85 x 10^5 kilometers * 1000 = 3.85 x 10^8 meters.
Now, we can calculate the time required using the formula:
Time = Distance / Speed
Time = (3.85 x 10^8 meters) / (299,792,000 meters/second)
Time = (3.85 x 10^8) / (299,792,000)
To simplify the calculation, we can divide both numbers by 100,000:
Time = 3.85 / 29.9792
Time ≈ 0.12852 seconds
Therefore, it takes approximately 0.12852 seconds for reflected sunlight to travel from the Moon to Earth.
