Question

given the distance between earth and sun is 1.6*10 power 8 km and when the velocity of light is 4*10 power km/sec the time taken for sunlight to reach the earth is in sec

Answer 1

Answer:

Explanation:

Given distance ( d ) = 1.6 × 10^8 km ;. velocity ( d) = 4 × 10^5 km/sec ; time =? ;. t = d / v; t = (1.6 × 10 ^8)/4 × 10^5 hence t = 0.4 × 10^3 s ; t = 400 s
