Question

According to observation and measurements, Neptune is at a distance of
4x10^12 m from the earth. When space travel becomes highly advanced do you think that man will be able to visit those Neptune?

(light travels 8x10³ m in one second and there are approximately 10^8 s in a year).​

Answer 1

Answer:

D=S/T is the formula of distance

3×10^8 is the value of 1joule

Answer 2

Answer:

It takes 5 years. So if anyone is way too interested to travel, then that man can surely do so

Explanation:

Distance = 4×10¹² m

Speed = 8×10³ m/s

Time required = Distance/Time = 4×10¹²/8×10³

Time = 5×10⁸ s

As given, 1 year has 10⁸ seconds

Thus it'll take about 5 years to travel to Neptune.
