Concept Introduction :
The relation between velocity, time and distance is as follows:
Answer to Problem 94A
Light can complete 86 round trips between the Earth and the Sun in 24 hr.
Explanation of Solution
Distance between Earth and Sun:
Calculate distance in m as,
In a round trip, distance will be double. So, distance will be
In one day 24 hrs are there.
Calculate no. of seconds in one day as,
Calculate time taken by light to calculate one round trip
So, in trip 1000 s is required.
So, no. of the round trip can be done by light is,
So, light can complete 86 round trips between the Earth and the Sun in 24 hr.
