Convert miles to meters = approx 1.5E11 meters
Then 3E8 m/s x # sec = 1.5E11
Convert to minutes by dividing the answer by 60 sec/min
Then 3E8 m/s x # sec = 1.5E11
Convert to minutes by dividing the answer by 60 sec/min
First, let's convert the distance from miles to meters:
9.37 x 10^7 miles = 9.37 x 10^7 miles * 1.61 x 10^3 meters/mile = 1.51057 x 10^11 meters.
Now, we can use the speed of light to find the time it takes:
1.51057 x 10^11 meters / (3.00 x 10^8 meters/second) = 5.035 x 10^2 seconds.
Therefore, it takes approximately 5.035 x 10^2 seconds for light from the sun to reach the Earth.
Given:
Distance = 9.37 x 10^7 miles
Speed of light = 3.00 x 10^8 m/s
To solve this using dimensional analysis, we'll follow these steps:
Step 1: Convert the distance from miles to meters.
1 mile is approximately equal to 1,609.34 meters.
So, the distance in meters is: 9.37 x 10^7 miles * 1,609.34 meters/mile
Step 2: Divide the distance by the speed of light to get the time.
Time = Distance / Speed of light
Let's calculate it step by step:
Step 1:
Distance(meters) = 9.37 x 10^7 miles * 1,609.34 meters/mile
Distance(meters) ≈ 1.50 x 10^11 meters
Step 2:
Time = (1.50 x 10^11 meters) / (3.00 x 10^8 m/s)
Time ≈ 5.00 x 10^2 seconds
So, it takes approximately 500 seconds for light from the sun to reach the Earth.
