Q. Given that earth-sun distance is $1.5 \times 10^8\,km$ velocity of light $3 \times 10^5 km \,s^{-1}$. The sun light reaches on earth in time

Motion in a Straight Line

Solution:

Speed = $\frac{Distance }{Times}$
i.e. Time = $\frac{Distance}{speed} = \frac{1.5 \times 10^8}{3 \times 10^5}$ = 500 s
