Answer 1

3.84*108^2?

Answer 2

All ryt lets do this !

Answer 3

ok

Answer 4

Time = \(\huge\frac{Distance}{Speed}\)

Answer 5

Speed of laser light which is a light =3*10\(^8\)m/s

Answer 6

ok

Answer 7

Here distance wil be 2*3.84*10\(^8\) since it is a round trip

Answer 8

Plug in the values and we will get the time

Answer 9

got it ?

Answer 10

yep makes sense
