Light from the sun reaches earth in 8.3 min. The velocity of light is 3.00 x 10^8 m/s. How far is earth from the sun.
distance=speed*time watch units.
To find the distance between the Earth and the Sun, we can use the formula:
Distance = Velocity x Time
Given that the velocity of light is 3.00 x 10^8 m/s and it takes light 8.3 minutes to reach Earth, we can substitute these values into the formula:
Distance = (3.00 x 10^8 m/s) x (8.3 min)
However, we need to first convert the time from minutes to seconds, since the velocity is given in meters per second. There are 60 seconds in a minute, so:
Time = 8.3 min x 60 s/min
Substituting this value into the equation, we have:
Distance = (3.00 x 10^8 m/s) x (8.3 min x 60 s/min)
Now we can calculate the final answer:
Distance = (3.00 x 10^8 m/s) x (498 s)
Distance = 1.494 x 10^11 meters
The distance between the Earth and the Sun is approximately 1.494 x 10^11 meters.
