Question

the sunlight reaches the earth in 8.5 minutes calculate the distance between the sun and the Earth if velocity of l
ight is 3 x 10 MS​

Answer 1

Answer:

d=1.49×10 to the power 11m

Explanation:

Velocity is defined as the rate of travel, and can be found using the distance formula.

Velocity=distance/time

Rearranging this formula we can solve for distance given velocity and time of travel.

d=vt

We are given velocity and time, and so can solve for distance, but if we plug in the values given;

d=(3.00×10 to the power 8m/s)(8.3minutes)

We can see that the units do not match up. Since seconds are the SI unit for time, we will need to convert 8.3 minutes to seconds.

t=(8.3minutes)(60seconds/minute)=(498s)

Now our units work out and we can solve for distance.

d=(3.00×10 to the power 8 m/s)(498s)

d=1.49×10 to the power 11m
