Question

if the distance between the sun and the earth is 1.5 into 10 power M and velocity of light in 3 into 10 power 8 metre per second then the time taken by a light ray to reach distance from the sun is

Answer 1

Since speed = distance/time,

then time = distance/speed.

Remember to convert the distance units to the same unit.

1.5x108 km x(1000m/1km) = 1.5x1011 m

Then (1.5x1011 m)/(2.997x108 m/s) = 500 seconds.

Answer 2

Answer:

hey

your answer = 500 seconds hope this will help u
